Hanna-Barbera

Background
Hanna-Barbera was originally formed in 1957 by Tom and Jerry creators and directors William "Bill" Hanna & Joseph "Joe" Barbera and live-action director George Sidney as "H-B Enterprises" after Metro-Goldwyn-Mayer shut down its animation studio. H-B struck a deal with Columbia Pictures Corporation to syndicate the cartoons on television in conjunction with Columbia's television division Screen Gems until 1966 and co-produced several cartoons in the early 1970s until 1974 and by Columbia Pictures Television from 1974-1975.

The company was renamed Hanna-Barbera Productions in 1959, and was later acquired by Taft Broadcasting in 1966; Taft was later renamed to Great American Broadcasting in 1987 after a buyout. It would then be renamed Citicasters in 1993 before finally being absorbed into Jacor Communications in 1997, who in turn was acquired by ClearChannel Communications (now iHeart Media) in 1999. In 1991, the studio was purchased by Turner Broadcasting, initially with help from the Apollo Investment Group. Bill Hanna and Joe Barbera both went into semi-retirement, yet continued to serve as ceremonial figureheads for the studio. The same year, the company was renamed H-B Production Co.; two years later, it was renamed Hanna-Barbera Cartoons, Inc.

In 1992, Turner launched the Cartoon Network, which had been built around reruns from the Hanna-Barbera and the Turner Entertainment Co. cartoon libraries (pre-1986 MGM, pre-1948 WB, and Associated Artists Productions cartoons). The same year in 1994, Turner turned Hanna-Barbera towards primarily producing new material for its Cartoon Network when Cartoon Network Studios was organized as a division of Hanna-Barbera Cartoons, Inc.

On October 10, 1996, Turner was bought out by Time Warner (now Warner Bros. Discovery). Ten days before William Hanna's death in 2001, Hanna-Barbera was folded into Warner Bros. Animation, and Cartoon Network Studios became a separate company and assumed production of Cartoon Network's output. Joe Barbera remained with Warner Bros. Animation until his death in 2006.

Up until 2017, Hanna-Barbera still survived as an in-name-only unit of Warner Bros. Animation for distribution and marketing of properties and productions associated with Hanna-Barbera's "classic" works. However, not all cartoons co-produced by Hanna-Barbera are owned by Warner Bros. Discovery, such as the following: Jeannie and The Partridge Family 2200 A.D. (Sony Pictures Television), The Fonz and the Happy Days Gang, Laverne & Shirley in the Army, Amigo and Friends, The Little Rascals: The Animated Series, and the 1970 Harlem Globetrotters cartoon (CBS Studios/CBS Media Ventures), Gravedale High, the international rights to Midnight Patrol: Adventures in the Dream Zone, and the 1978 Godzilla cartoon (NBCUniversal Television), Capitol Critters (20th Century Fox Television/20th Television and later Disney Platform Distribution), Pink Panther and Sons, The Adventures of Sinbad Jr., and Bill & Ted's Excellent Adventures (first season co-produced by H-B and the second season was co-produced by DIC and MGM Television), Benji, Zax & the Alien Prince (Mulberry Square Productions), and most of the theatrical library. Warner Bros. has no rights whatsoever to any of the productions listed. As stated below, the name would be revived in said year.

1st Logo (December 3, 1957-March 26, 1960)
Visuals: Over a yellow background sits two boxes, one and one, joined together unevenly. There is an "H" in the box and a "B" in the  box. The text appears as "an HB PRODUCTION".

Variants:
 * On later shows, the background is dark green, the "H" box is lavender, and the "B" box is . The text appears as "AN HB ENTERPRISES CARTOON". Sometimes the letters appear smaller.
 * A variant of the original variant has the H-B Boxes, but the text is extended out to read "Hanna-Barbera".

Technique: A still image.

Audio: The opening theme of the cartoon.

Availability:
 * The original variant only appeared on The Ruff & Reddy Show. It is intact on home media releases of the series.
 * The later variant is more common, however. It can be seen on early episodes of Yogi Bear, Pixie & Dixie and Mr. Jinks, Huckleberry Hound, and the Quick Draw McGraw short "Scary Prairie" among other shorts.

Legacy: Despite its short lifespan, this logo seems to have inspired Cartoon Network's 2004 redesign.

2nd Logo (1959-1966)
Visuals: On either a yellow (or pink) background, there is a pale turquoise (or electric blue) "splotch". Inside are the words "HANNA-BARBERA" in a "scrawly" font used for crediting the two producers on latter-day MGM shorts and many of the original H-B Productions series. The word "A" and "PRODUCTION" appear above and below the logo.

Variants:
 * In 1961, the "Hanna-Barbera" script logo was a curvy font with looped edges on the top and bottom of the "B".
 * Starting in late 1961, the word "Hanna-Barbera" appears in a cursive font commonly known as Tabitha.
 * An in-credit version of the logo without the splotch exists.

Technique: A still image.

Audio: The opening or closing theme of the cartoon.

Availability: Seen on some HB shorts of the era, and at the end of several 1960s series such as The Jetsons and Top Cat, as well as the special Yogi Bear's Birthday Party.

3rd Logo (February 26, 1967-March 27, 1974, March 4, 2003-April 7, 2009)
Images=

Videos=

Visuals: On a black background, a large, blocky "HB" symbol begins to zoom in rapidly from the center. When it comes to a point where it nearly engulfs the screen, the background suddenly becomes yellow-orange and the "HB" turns a darker orange. On top of the "HB", the words "a", "hanna-barbera", and "production" all appear in black, with the "a" inside a square the same color as the background.

Bylines:
 * February 27, 1967, September 25, 1971-March 27, 1974: Bylineless
 * September 7, 1968-1969, September 12, 1970-November 17, 1972: The Taft corporate logo next to the words "a division of taft broadcasting company".
 * September 6, 1969-January 17, 1970: The byline "A Taft BROADCASTING COMPANY", with "Taft" in form of its logo.

Variants:
 * There is a very early version of the logo where the three small rectangles appear, the outer two stretching down, the one in the center extending up, then they stretch, break up and multiply to become an orange box containing a large, black stylized "HB" cutout. Then, the box grows to become an  background, the black "HB" zooms out, disappears, and the normal text appears as a boxed "a" appears formed from the black "HB" since it zoomed out from the spot and the same "HB" (using the same style as the black one) slowly fades in.
 * On some early episodes of The New Adventures of Huckleberry Finn, it has the same starting animation, with the rectangles moving the directions they're supposed to extend in instead of stretching before they actually do. When the black zooming "HB" disappears (it doesn't move off its path), it cuts to a "HB" with the text already on it in, with the small "a" box colored dark blue and the letter in yellow. It features a byline reading "a division of Taft Broadcasting Company" next to a small Taft logo on the bottom.
 * An alternative version exists on some shows from the 1969-1970 season. It starts off with the formation of the HB box from the earlier versions, but instead of the box zooming out, it turns capri while the background turns . Then, "a hanna-barbera production" and the Taft byline/logo fade in. The "a" in the HB box is on top of a denim blue box with an outline.
 * On Cartoon Network and Boomerang U.S. reruns of the Scooby-Doo, Where Are You! episode "Go Away Ghost Ship", the 1969 version of the logo is sped up due to time compression.
 * A similar version exists on Where's Huddles? where the box zooms out instead of fading to the already formed logo, a la the initial 1967 version. There is also no Taft byline/logo as well, and the background is.
 * For a short period, Taft's corporate logo, alongside a byline reading "a division of Taft Broadcasting Company”, appear. This appears to coincide with the logo being used "standalone", with its own music. Box logos that are appended to the ends of shows and have the show's music playing usually do not have the byline. However, there are some exceptions, such as The Thanksgiving That Almost Wasn't, which featured the logo attached to the end of the credits with the end of the show's theme playing under it, but features a Taft logo and byline; and The Funky Phantom and Yogi's Ark Lark, which feature the "standalone" variant of the logo (with its own music), but no Taft logo or byline.
 * Starting in 2003, with the release of Scooby-Doo and the Legend of the Vampire, the "Scooby All-Stars" logo was phased out and replaced with a recreation of this logo. The H-B now zooms-in much more smoothly before cutting to the finished logo. This was seen on all 2002-2009 made-for-video Scooby-Doo movies; however, beginning with Scooby-Doo! Abracadabra Doo, it now simply ends with the Warner Bros. Animation logo, as all made-for-video Scooby-Doo movies were produced at that studio.

Technique: Cel animation.

Audio:
 * February 26, 1967-December 29, 1968: A series of four glockenspiel notes and then three brass-band/accordion notes mixed with three glockenspiel chimes. It was written by then Hanna-Barbera musical director Ted Nichols.
 * September 7, 1968-September 16, 1972: A whimsical flute/xylophone jingle, ending with a held-out muted trumpet stinger. It was also written by then-Hanna-Barbera musical director Ted Nichols, used only when the logo wasn't attached to the end of the show and had the show's end credits music playing over it. You can hear this at the end of the Dastardly & Muttley, Penelope Pitstop, and Josie and the Pussycats closing title tracks on the European H-B music CD Tunes from the Toons: The Best of Hanna-Barbera.
 * September 11, 1971-March 27, 1974: The end title theme of the show, or none.

Audio Variants:
 * On the Boomerang streaming service's print of Yogi's Ark Lark, the 1970-1974 version of the Screen Gems "S from Hell" logo music plays under this logo, possibly due to poor editing/plastering.
 * On the HBO Max and Blu-ray prints of the Josie and the Pussycats in Outer Space episode "The Hollow Planet", the bylineless version of the regular 1968 logo uses the first half of the 1994 HB "Comedy All-Stars" logo's audio due to a reverse plastering error.
 * On both the Australian version of Cartoon Network and Teletoon Canada airings of The Scooby-Doo Show episode "Hang in There Scooby-Doo", the 1969 version of the logo used the 1979 "Swirling Star" music due to an editing error.
 * On Romanian dubbing prints of Dastardly & Muttley in Their Flying Machines and also on the 1997 UK VHS release of The Perils of Penelope Pitstop: Bumper Edition, the 1969 version of the logo is silent.

Availability:
 * The regular 1968 version of the logo with the Taft byline was last seen on the The Adventures of Gulliver episode "Little Man of the Year", and on most episodes of Wacky Races on Boomerang (it is plastered with the 1994 "Comedy All-Stars" logo on the DVD release and the Boomerang streaming service) and the bylineless variant of the regular 1968 version the logo also appears on The Amazing Chan and the Chan Clan, Super Friends, the TV movie Yogi's Ark Lark, The Flintstone Comedy Show, and most episodes of The New Scooby-Doo Movies on DVD and Blu-ray (some episodes on the Boomerang streaming service have it, others plaster it with the 2003 Warner Bros. Television logo, and some cut off before the logo appears).
 * The regular 1968 version of the logo with the Taft byline was also originally seen on The Harlem Globetrotters 1970 animated series and season 2 of Scooby-Doo, Where Are You! (the former was retained on TV Land airings in the early 2000s, with the 1995 silent Paramount Domestic Television logo following; the latter is available on DVD, Blu-ray and HBO Max, respectively).
 * Some episodes of Josie and the Pussycats have the regular 1968 version of the logo with the Taft byline plastered over with both the blacked out 1979-era variant of the original "Swirling Star" and 1994 "Comedy All-Stars" logos on DVD and the Boomerang streaming service, but is restored on all episodes of that show on both Blu-ray and HBO Max, respectively.
 * The 1968 logo with the ending of the show's theme also appears on the Warner Archive released DVD releases of shows, such as the two 1973 animated series Speed Buggy and Butch Cassidy and the Sundance Kids.
 * The original 1967 version is still kept on its only use, the 1967 NBC live action/animated special Jack and the Beanstalk, whenever someone decides to show it, but it's still retained on VHS prints and the DVD from Warner Archive; however, it is not intact on the Boomerang streaming service's print.
 * The alternate 1968 version is only seen on the live action/animated TV series The New Adventures of Huckleberry Finn, and is also preserved on the DVD set from Warner Archive.
 * Prior to 2004, the 1969 version of the logo was nearly impossible to find, mainly due to chronic plastering. The first season of Scooby-Doo, Where Are You! also suffered this as well, first with a blacked out 1979-era or sometimes a blacked out 1983-era "Swirling Star" logo, then with the 1994 "Comedy" variant of the "All-Stars" logo when reran on TBS in 1995, and finally the 1994 "Action" variant of the "All-Stars" logo in 1998.
 * The 1969 version of the logo can be found on a few Hanna-Barbera DVD box sets, such as Scooby-Doo, Where Are You!: The Complete First and Second Seasons, which means the logo is now more common than it was prior to the DVD release (it is also preserved on both the Blu-ray release and HBO Max followed by the 2003 WB Television logo; however, it is cut out on the Boomerang streaming service's HD prints of the series).
 * The 1969 version of the logo also appears at the end of a 16mm print of the Scooby-Doo, Where Are You! episode "What the Hex Going On?" from South Africa, which is then followed by the 1971 Viacom "Pinball" logo.
 * For a long time, the most visible source of the 1969 version of the logo was the end of both American Cartoon Network and Boomerang prints of the Scooby-Doo, Where Are You! episode "Go Away Ghost Ship", which showed the logo in a PAL-to-NTSC transfer.
 * The 1969 version of the logo also appears at the end of the Scooby-Doo, Where Are You! episode "Bedlam in the Big Top" included on the 2002 UK VHS release of Scooby-Doo and the Ghoul School (1988) from Warner Home Video, due to that episode and "A Clue for Scooby-Doo" being bonus episodes included on that release.
 * The 1969 version of the logo also appears on DVD releases of The Perils of Penelope Pitstop, with the 2003 WB Television logo playing the 1994 theme in low tone following it; however, it is also cut out on the Boomerang streaming service as well.
 * The 1969 version of the logo was also originally seen on The Cattanooga Cats, but was plastered over with the 1988 version of the 1986 "CGI Swirling Star" logo when it was rerun on Cartoon Network and Boomerang.
 * The 1969 version of the logo was also seen on Dastardly & Muttley in Their Flying Machines when last rerun on Boomerang; however, it is also strangely been cut out on both the DVD release and the Boomerang streaming service, respectively.
 * The 1970 variant appears on the Warner Archive DVD release of Where's Huddles, but Boomerang U.S. airings plastered this logo with the 1988 version of the 1986 "CGI Swirling Star" logo too.
 * The 1969 version of the logo also strangely appeared on The Scooby-Doo Show episode "The Headless Horseman of Halloween", as seen on a 1990 USA Network broadcast, which is then followed by the 1988 Worldvision Enterprises logo.
 * The 1969 version of the logo with the 1979 "Swirling Star" music also strangely appeared on both the Australian version of Cartoon Network and Teletoon Canada airings of The Scooby-Doo Show episode "Hang in There, Scooby-Doo", which is then followed by the short version of the 1987 Turner Entertainment "CGI Globe" logo.
 * The silent variant of the 1969 version of the logo also appears on Romanian dubbing prints of Dastardly & Muttley in Their Flying Machines and on the 1997 UK VHS release of The Perils of Penelope Pitstop: Bumper Edition, which is then followed by the short version of the 1987 Turner Entertainment "CGI Globe" logo on the latter.
 * The regular 1968 version of the logo with the Taft byline was also seen at the end of the first season of The Banana Splits Adventure Hour when it was originally aired on NBC.
 * The bylineless variant of the regular 1968 version of the logo is also cut out on The New Scooby-Doo Movies episode "The Caped Crusader Caper", when it appears as a bonus feature on the 2018 DVD release of Scooby-Doo and Batman: The Brave and the Bold.

Legacy: It is the first logo from the company to be animated. The early 1967 and 1969 versions are not as well-known as the common 1968 version.

4th Logo (September 7, 1974-April 7, 1979)
Images=

Videos=

NOTE: On the 3rd video, the logo plays at 0:27.

Visuals: The sequence starts on a pattern of five columns, each filled with the words "HANNA-BARBERA". The words are colored so that they form a rainbow pattern (similar to The Mary Tyler Moore Show). Suddenly, the words start disappearing, from the top starting on the first column, and from the bottom starting with the last column. The words disappear until one last "HANNA-BARBERA" is left, which enlarges and "morphs" into a skewed, stylised "H-B", filled with a rolling rainbow pattern with numerous "HANNA-BARBERA"s in it. Below, the words "HANNA-BARBERA PRODUCTIONS, INC." appear.

Trivia: This logo is used on backgrounds of the end titles of The Scooby-Doo Show and Dynomutt, Dog Wonder.

Bylines:
 * September 7, 1974-May 11, 1978: Bylineless
 * December 4, 1977, September 9, 1978-April 7, 1979: "A TAFT BROADCASTING COMPANY"

Variants:
 * A variant has been seen on only a couple of TV movies of the era, such as the live-action telefilm The Gathering. Mainly nicknamed "Solid Rainbow H-B", it was a still shot with more solid colors (yellow,, , pink, , ) and segmented lines running inside the design. It's also horizontal and the byline is still intact.
 * On the final episode of Hong Kong Phooey, "Comedy Cowboys", the words in the end result do not move with the rainbow pattern.
 * A variant features the "H-B" in a more straightforward stencil font, more towards the top of the screen and a large lime green/olive-brown "77" in the same style underneath, made out of several vertical lines. There are no "HANNA-BARBERA"s in either figure. The variant begins with this design cascading and forming on-screen, followed by four "starbursts" appearing,. The whole scene then gives way to four small circles that join together and zoom in to become a giant rotating circle, surrounded by a string of flashing live-action lights. Within the circle appear several (fairly obscure) Hanna-Barbera cartoon characters: Precious Pupp, Mumbly, Atom Ant, Winsome Witch, Squiddly Diddly and Chief Winchley, Pa Rugg from The Hillbilly Bears, and Secret Squirrel. The circle and lights then disappear, and (to the beat of the sound effects in the music) a starburst "explodes" three times before the "HB77" logo forms again onscreen. At the bottom for part of the animation is the text "Dolphin Productions/New York", referring to Dolphin Productions, a New York-based company that incorporated the first computer-generated effects in TV logos and advertisements, being the production company behind this variant. This logo was only used in 1977 and was created as an interstitial for the Hanna-Barbera programming block "HB '77" that aired on Rede Globo in Brazil that year. Another variant is rumoured to exist with an "HB 78" logo.
 * Starting in 1977, the logo does not enlarge, and is also smaller as a result.

Technique:
 * For the main logo: Camera-controlled cel animation, produced by Hanna-Barbera themselves.
 * For the "H-B '77" variant: A mix of Scanimation and traditional animation.

Audio: Usually just the end theme of the show. None for the TV movie variant. The "HB '77" variation has instrumental bits of the theme to the 1975 Tom & Jerry Show, complete with the sound effects heard in that show's intro sequence.

Audio Variants:
 * Some repeats would have the 1968-1974 theme, which seems to be synchronized perfectly with the logo.
 * On all TV airings, VHS prints and the Warner Home Video DVD print of Scooby Goes Hollywood, the 1979 "Swirling Star" logo theme played. This was probably because since the special was from December 1979, it most likely was used to plaster the "Swirling Star" logo.
 * The "Swirling Star" music has also been heard on both an early 2010s Australian rerun and a Teletoon Canada airing of The Scooby-Doo Show episode "Creepy Cruise" and also on a USA Cartoon Express airing of the Jana of the Jungle episode "Katuchi Danger" as well.

Availability: It's usually preserved on Hong Kong Phooey, The Super Friends Hour, Clue Club, Jabberjaw, Challenge of the Super Friends, Dynomutt: Dog Wonder, Captain Caveman and the Teen Angels, seasons 1-3 of The Scooby-Doo Show, and some episodes of Yogi's Space Race whenever someone decides to show them.
 * However, on some prints of the latter, the credits are either cut off early or plastered with the 1988 version of the 1986 "CGI Swirling Star"; the same case was also on Boomerang airings of Galaxy Goof Ups (but intact on both on Boomerang streaming service's prints.)
 * This was also plastered by the 1979, 1982 or 1983 Swirling Star logo on USA Network's USA Cartoon Express on such shows as Jabberjaw, Jana of the Jungle, Hong Kong Phooey, Clue Club, and The New Fred & Barney Show (the latter also uses the 1983 "Swirling Star" logo on the Boomerang streaming service's prints, while 2002 Boomerang U.S. airings used the the 1988 version of the 1986 "CGI Swirling Star" logo).
 * This logo is also available on DVD releases of Hong Kong Phooey, seasons 1 and 3 of The Scooby-Doo Show (also available on Blu-ray and HBO Max with the 2003 WB TV Distribution logo appearing after it), Dynomutt: Dog Wonder, and the Warner Archive release of Captain Caveman and the Teen Angels (also intact on the Boomerang streaming service).
 * The 1977 version of this logo was also seen on the 1st season of The All-New Popeye Hour.
 * The original version of this logo also seen on The Tom & Jerry Show (1975) before the 1973 MGM Television logo (however, it is blacked out on both the Boomerang streaming service and Tubi prints of the series).
 * The original version of this logo also appears on The Scooby-Doo Show seasons 1-3 on HBO Max, followed by the 2003 WB TV Distribution logo at the end.
 * The version with the 1979 "Swirling Star" music appears on all TV airings, VHS prints and the Warner Home Video DVD print of Scooby Goes Hollywood, and also on both an early 2010s Australian rerun and a Teletoon Canada airing of The Scooby-Doo Show episode "Creepy Cruise" and a USA Cartoon Express airing of the Jana of the Jungle episode "Katuchi Danger".
 * The original version of this logo was also seen on the 2023 Boomerang U.S. airings of Jabberjaw, which is then followed by the 1988 Worldvision Enterprises logo.

Legacy: Many years later, Warner Bros. Animation would do a modernized version of this logo.

5th Logo (September 11, 1976-March 1, 1987)
Visuals: Just an in-credit logo that has "HANNA-BARBERA" in a bold, "tubular" font similar to the latter-day Filmways logo. The words "A" and "PRODUCTION" appear below the logo.

Opening Variant: The openings of The Scooby-Doo Show and Dynomutt, Dog Wonder had "PRESENTS" below the logo.

Variant: On Scooby Goes Hollywood, the "HANNA-BARBERA" text sparkles.

Technique: A still image.

Audio: The opening or closing theme of the show.

Availability: Usually seen on series produced from 1977 to 1986.
 * The last new shows to use this variation of "HANNA-BARBERA" were season 1 of Pound Puppies, the 1986 version of Jonny Quest, and season 1 of The Flintstone Kids, among shows.
 * Air Music and Media Group plc's releases of The All New Popeye Hour (branded as just Popeye) remove this logo and replace it with copyright information for King Features Entertainment instead.

6th Logo (September 8, 1979-July 6, 1990)
Images=

Videos=

Visuals: On a black background, a white star swirls down from the top of the screen, leaving behind a rainbow trail. It then settles into the center of the screen as it twirls, occasionally shrinking and twisting, forming a circular trail. It then twists into the middle of the circle and comes to a stop. The words "Times New Roman" in Belwe Medium font appear below.

Trivia: Basically, this is the Taft swirling star as seen on the Taft International Pictures logo, only rainbow colored. The logo was designed by Saul Bass.

Bylines:
 * September 8, 1979-January 31, 1981: "A TAFT BROADCASTING COMPANY" (in a white font)
 * September 12, 1981-May 20, 1986: "A DIVISION OF THE TAFT ENTERTAINMENT COMPANY"
 * In 1982, the 1981 byline was altered/amended with "A DIVISION OF" over "THE TAFT ENTERTAINMENT COMPANY".
 * In 1983, the 1981 byline appears in a large yellow font, and the logo also appears smaller in this version.
 * July 6, 1990: "A GREAT AMERICAN BROADCASTING COMPANY"
 * Post-1988 prints of H-B shows from this era often have the Taft byline blacked out (possibly for legal reasons).

Variants:
 * In 1990, a special version of this was used at the end of Jetsons: The Movie. This features the same animation, but "Hanna-Barbera" is written in the familiar cursive "script" font first introduced in 1987, and the animation freeze-frames very shortly before the original animation ends. This variant also features a Great American byline, and is the only H-B logo to do so.
 * Beginning in 1984, Hanna-Barbera created an opening logo to use at the beginning of some of their shows. It's the same as the closing logo, but fades in during the middle of the animation. The text is changed, "Hanna-Barbera" is larger, and a small "PRESENTS" is shown below. This opening variant (with the regular music) can still be found at the beginning of every episode of The Smurfs on Boomerang.
 * There is also a variant seen on the 1986 film GoBots: Battle of the Rock Lords and at the end of the 1982 film Heidi's Song, in which there is a large "A Hanna-Barbera Production" byline and the logo is tiny in size.
 * On an older print of one episode of The Scooby-Doo Show, the logo is moved up a bit so the Taft byline cannot be seen.
 * On the TV special A Yabba-Dabba-Doo Celebration: 50 Years of Hanna-Barbera, an IATSE disclaimer appears below the logo. This also appears on a pre-launch reel for Cartoon Network.
 * On an earthquake preparation video made for the Los Angeles Earthquake Preparation Program, the text on the bottom says "Hanna-Barbera PRESENTS" with the text below in a Helvetica font. The white star then suddenly zooms in and engulfs the screen, and flashes to the video's introduction. At the end, the "Swirling Star" is smaller and the text says "A HANNA-BARBERA PRODUCTION FOR CITY OF LOS ANGELES EARTHQUAKE PREPARATION PROGRAM" (in the same font as the Taft byline).
 * Another dark/deteriorated variant was seen on a recent Boomerang airing of the Smurfs episode "The Smurfs' Time Capsule", where the trail was almost entirely invisible. Only the star and the text could be seen.

Technique: Motion-controlled cel animation.

Audio: Best described as "futuristic synthesized music", the sequence starts out with ascending and descending chimes mixed with a "whoosh" sound with each revolution of the star. When the star stops, the entire thing culminates in a somewhat gentle, but abrupt acoustic guitar and bass chord as the chimes finish in the background. This was written by Hoyt Curtin, and samples "Moog Bullet (24)" by Alan Hawkshaw.

Audio Variants:
 * The opening variant used a sweeping chime sound; however, 1980s Jetsons episodes feature a rendition of the Jetsons' doorbell (the "Meet George Jetson" piece of the theme rendered in chimes).
 * The 1990 variant used a majestic version of the "Meet George Jetson" theme in the style of The Simpsons theme song (or more precisely, Danny Elfman).
 * On VHS releases of 1985 episodes of The Greatest Stories: Tales from the Bible, the logo is silent.
 * Some shows have been known to use the first variant with a blacked-out Taft byline, but with the 1968 "Zooming H-B" fanfare. This was chiefly used to update the logo on Scooby-Doo, Where Are You!, but also spread to other shows as well, including post-1988 reruns of Casper's First Christmas (1979) and Top Cat and the Beverly Hills Cats (1988), and was also spotted on an unknown episode of Josie and the Pussycats. This instance also happened on the 1982 The Smurfs episode "The Adventures of Robin Smurf", and another instance on a 1986 syndicated rerun of The Smurfs. This variant was somewhat common, but became rare when Warner Bros. updated the prints of Scooby-Doo, Where Are You! in 1997, and tacked on the 1994 "Action All-Stars" logo.
 * On a 1984 Canadian VHS release of The Three Musketeers, the logo is silent; however, when the logo freezes, a note from some other cartoon theme plays, then the usual synthesizer music begins.
 * On Family Channel airings of The All-New Popeye Hour, some reruns of the 1979-81 episodes would have this logo and the music on it sped-up due to time compression.
 * On Rock Odyssey (1987), the 1986 releases of The Greatest Adventure: Stories From the Bible, early 1990s prints of the 1978 Godzilla cartoon, and Boomerang U.S. airings of CB Bears, the ending of the show's theme is heard over the logo.
 * On the 1986 theatrical re-release of Hey There, It's Yogi Bear (1964), the film's opening music cue plays over the "presents" variation of the logo. At the end, the standard version of the logo plays silent.
 * The 1991 Cartoon Network pre-launch promo has an announcer say "And since we bought Hanna-Barbera..."

 * Currently seen on The Smurfs on Boomerang, and was also shown on Super Friends: The Legendary Super Powers Show, the first two seasons of The Snorks, The Yogi Bear Show, some episodes of Josie and the Pussycats, Josie and the Pussycats in Outer Space (intact on episodes 6 and 8 on the Warner Archive DVD release), season 1 of Scooby-Doo and Scrappy-Doo (with the 2001 low tone WBTVD logo following; it was kept intact on HBO Max's prints, but with the 2003 WBTV logo following instead), four episodes of Galaxy Goof Ups, most 1982 episodes of The Richie Rich Show, a few existing 1980s syndicated remastered prints of Top Cat, the 1985-86 season of The Jetsons, and The 13 Ghosts of Scooby-Doo when last rerun on Boomerang (which also retained this logo on its DVD release and on the Boomerang streaming service).
 * However, many prints still have the logo's Taft bylines blacked out or bylineless. You're more likely to find the Taft byline intact on lesser-seen shows and/or shows produced by H-B, but distributed by other companies.
 * The 1985 episodes of The Jetsons don't retain this on remastered prints due to plastering by the 1994 Comedy All Stars logo, but it's intact on HBO Max.
 * The 1983 variant of this logo (w/ Taft byline) also appears right after the 1968 "Zooming H-B" on the DVD releases of The Pebbles and Bamm-Bamm Show and The Flintstones Comedy Show.
 * It also recently appeared after the 1968 "Zooming H-B" logo on the former's episode "Focus Foolery" when last rerun on Boomerang as well.
 * The H-B Presents logo with the "Meet George Jetson" chimes is rare, and so far has been spotted on several Jetsons episodes on the Boomerang streaming service and on HBO Max.
 * It's also appeared on airings on Teletoon Canada.
 * The blacked out 1983-era variant of this logo also appears at the end of Boomerang and DVD prints of Yogi and the Invasion of the Space Bears and Scooby-Doo and the Reluctant Werewolf (both 1988), plastering the next logo.
 * However, it is cut from the Boomerang streaming service's print of the latter, while the Warner Archive DVD release of the former plasters it with the 11th logo instead.
 * The blacked out 1983-era variant of this logo also appears at the end of a Tubi streaming print of S4E16 of The Smurfs, which is then followed by the 1988 Worldvision Enterprises logo.
 * The blacked out 1983-era variant of this logo also appeared on the late 1980s prints of Alice in Wonderland or What's a Nice Kid Like You Doing in a Place Like This? (1966) and 20,000 Leagues Under the Sea (1973), respectively, which is then followed by the 1988 Worldvision Enterprises logo.
 * The blacked out 1983-era variant of this logo was also seen on a 1995 Cartoon Network U.S. airing of the Scooby-Doo, Where Are You! episode "Never Ape an Ape Man".
 * There are also some prints with this logo (with b/o byline) plastering the next logo.
 * The "A Hanna-Barbera Production" variant is rare, only seen on the two theatrical films mentioned.
 * On The Scooby-Doo Show episode "Jeepers! It's the Jaguaro!", the 1981 variant of this logo plasters the 1974 H-B logo.
 * Oddly enough, this logo (w/blacked-out Taft byline) also plasters the Fred Flintstone logos on VHS releases of Tom & Jerry Kids.
 * This was also seen on the 1985 TV special/pilot episode of Pound Puppies.
 * The "presents" variant was also seen on Challenge of the GoBots and The Flintstone Kids, as well as DVD releases of the 1988 TV movie Scooby-Doo and the Reluctant Werewolf and at least one episode of Wake, Rattle & Roll (odd for the latter three, considering the logo was no longer used by this point); it was also used as part of the intro for the syndicated cartoon block The Funtastic World of Hanna-Barbera.
 * The logo was also seen on some pre-Turner prints of The Scooby-Doo Show on Cartoon Network Australia.
 * It was also previously seen on season 1 reruns of Shirt Tales and plastered over with the 1986 "CGI Swirling Star" on season 2 reruns on Boomerang.
 * This version, the 1986 "CGI Swirling Star", and the 1994 "All Stars Comedy" logos below have plastered the 1974 H-B Rainbow logo on Boomerang reruns of Laff-a-Lympics.
 * This was also retained on early 2000s TV Land airings of The Fonz & The Happy Days Gang, which is then followed by the 1995 Paramount Domestic Television logo (said logo was silent except for two episodes).
 * It has also been seen on some episodes of Amigo and Friends.
 * The 1983 variant of this logo with the Taft byline also appears on The New Scooby and Scrappy-Doo Show episodes "Scooby the Barbarian", "No Sharking Zone", "Scoobygeist" and "The Quagmire Quake Caper" included on the 2019 UK DVD release of Best of Warner Bros. 50 Cartoon Collection: Scooby-Doo! from Warner Bros. Home Entertainment, and at the end of the 1986 UK VHS release of GoBots from The Video Collection (which is then followed by the 1984 LBS Communications logo on the latter) and was also seen on Rock Odyssey (1987) (even on an old TVE 2/La 2 airing, which is then followed by the 1988 Worldvision Enterprises logo), as well as at the end of Light TV airings of Pink Panther and Sons (which is then followed by the 1996 MGM Domestic Television Distribution logo), and appears at the end of the 1989 U.S. VHS release of The Man Called Flintstone (1966).
 * The 1983 variant of this logo was also seen on an October 3, 1996, UK airing of The New Scooby and Scrappy-Doo Show episode "The Fall Dog" on CITV, which is then followed by the still variant of the 1988 Worldvision Enterprises logo.
 * The original version of this logo with both the Taft byline and 1968 "Zooming H-B" fanfare also appears at the end of the Scooby-Doo, Where Are You! episode "Nowhere to Hyde", included on the 2001 UK VHS release of Scooby-Doo and the Cyber Chase from Warner Home Video, which is then followed by the 1988 Worldvision Enterprises logo, due to that episode and "Which Witch is Witch?" being bonus episodes included on that release.

Legacy: Perhaps Hanna-Barbera's most famous closing logo. It's a favorite among people who grew up watching TV during this time or watching Hanna-Barbera's shows on Cartoon Network in the 1990s. It was referenced many years later by its successor, Hanna-Barbera Studios Europe.

7th Logo (October 26, 1985)


Visuals: Over a space background, the logo starts with stars zooming by. Then, moments later, the metallic text "Hanna-Barbera " and the word "PRESENTS " flies in from the center. The text shines, and then the text zooms away.

Technique: Computer animation.

Audio: A rock guitar theme.

Availability: It was seen on the specials Pound Puppies and Star Fairies, which was originally aired in syndication.

8th Logo (September 13, 1986-1992; November 18, 1998-August 9, 2002)
Images=

Videos=

Visuals: An updated version of the 6th logo, but now done in CGI. The trail is now metallic, and the star now realistically twists and turns and has a nice shine effect when the logo fully forms. The text and the respective company byline are in a different font and are slightly smaller.

Bylines:
 * September 13, 1986-July 16, 1988: "Times New Roman"
 * September 10, 1988-1992; December 15, 1997: Bylineless (Great American Broadcasting era)
 * November 18, 1998-February 9, 2001, April 20, 2001, May 4, 2001, July 19, 2002: "A Time Warner Company"
 * June 28-August 9, 2002: "An AOL Time Warner Company"

Variants:
 * The 1988-1992 version often has the logo slightly enlarged.
 * On some shows, the bylineless version has the logo shifted up.
 * A still variant was seen on The Pirates of Dark Water and on 1992 episodes of The Greatest Adventure: Stories From the Bible, with all names and bylines completely blacked out and replaced with "HANNA-BARBERA, INC." in a generic font. This also sometimes plastered the custom H-B logo at the end of Fish Police.
 * An updated version of this logo was used beginning in 1998. All names and bylines are completely blacked out, and instead, the text "Impact" (in the Compacta font), with the Time Warner (later AOL Time Warner from June 28-August 9, 2002) byline below it, fades in below the logo. Plus, the star does not shine after the logo forms. When the Cartoon Network Productions logo is to follow this, that logo zooms in from the star's center point and fills the screen.
 * Sometimes, the regular 1986 version of this logo also carries a blacked out byline where the Taft byline usually is.
 * Copyright dates may be substituted for the "Hanna-Barbera Productions" text.
 * An out-of-sync version exists on a rerun of the season 3 The Jetsons episode "Crime Games"; the music comes in slightly too early on this variant, so the logo freezes and the text appears about halfway through the final note of the theme.

Trivia: According to creator Craig McCracken, he was the one that chose this logo to appear at the end of The Powerpuff Girls, as opposed to a more current one, due to it being the one he grew up with.

Technique: CGI by Hanna-Barbera software designers James Mahoney and Bennett Leeds.

Audio: The Hoyt Curtin-composed theme from the 6th logo.

Audio Variants:
 * The closing theme of the show was used on shows such as recent reruns of Jana of the Jungle (due to plastering the 6th logo), the 1988 series The Completely Mental Misadventures of Ed Grimley, the final season of The Smurfs, The Flintstone Kids' Just Say No Special, and Cartoon Network and Boomerang airings of The Smurfs 1987 Christmas special "'Tis the Season to Be Smurfy".
 * On Boomerang airings of The Flintstone Comedy Show, the logo uses the end theme of the show (carried on from the 1968 logo which preceded this variant), and halfway through, it cuts to the regular music already in progress.
 * On The Powerpuff Girls episode "Dream Scheme/You Snooze, You Lose" and the 1999 Dexter's Laboratory special "Ego Trip", two recordings of the same theme play simultaneously, making the music a little louder.
 * On Boomerang airings and HBO Max prints of the 1986 revival of Jonny Quest, the logo is silent.

Availability:
 * The original version is currently seen on season 6 episodes of The Smurfs and A Pup Named Scooby-Doo when rerun on Boomerang (the latter show also preserves the logo on DVD releases and the Boomerang and Tubi streaming services), and was last seen on most episodes of Galaxy Goof Ups, seasons 3 and 4 of The Snorks, Fantastic Max, season 1 of Pound Puppies, The New Fred & Barney Show, and The Pirates of Dark Water when previously rerun on Boomerang, and used to be seen on some 1982 episodes of Scooby Doo and Scrappy Doo (which plasters the 1982 "Star" and the Ruby-Spears logo) when aired on Cartoon Network in the late 1990s to mid-2000s.
 * Cartoon Network airings of the Johnny Bravo episode "Under the Big Flop" also used the 1988 version of this logo instead of the standard "Character Portrait II" logo, possibly due to an editing mistake.
 * The 1998 version of this logo can be seen on most reruns and DVD releases of the first four seasons of The Powerpuff Girls, as well as the 1999 Dexter's Laboratory special "Ego Trip". Beginning with the Powerpuff Girls episode "Keen on Keane / Not So Awesome Blossom", the Cartoon Network Studios logo is used in place of this logo instead.
 * The version with the Taft byline can also be spotted at the end of the Scooby-Doo TV movies Scooby-Doo Meets the Boo Brothers (1987) (except for both the 1989 UK VHS release from Lollipop Video and the Boomerang streaming service's print, respectively, but intact on the iTunes HD remastered print, where it is followed by the 1981 Worldvision Enterprises logo), Scooby-Doo and the Ghoul School (1988) (also intact on the iTunes HD remastered print, which is then followed by the 1981 Worldvision Enterprises logo, once again) and Top Cat and the Beverly Hills Cats (1988; however, pre-2015 Boomerang U.S. airings plaster it with the blacked out 1979-era variant of the previous logo with the 1968 "Zooming HB" fanfare).
 * Overseas prints of Scooby-Doo and the Reluctant Werewolf also retain this logo as well (however, it is plastered with the blacked out 1983-era variant of the previous logo on domestic prints).
 * Also added to the end of some 1960s shows with no logo. It's sometimes seen at the end of shows that originally had an older H-B logo or one of the early 1990s in-credit logo variations, but that's rather rare as well. It has, however, recently happened on Boomerang reruns of the Cattanooga Cats, as well as an airing of the pilot episode of Yogi's Space Race on May 8, 2010.
 * The version with the Taft byline still exists on The Flintstone Kids (which is plastered on the WBHV Saturday Morning DVD by the 1994 "Comedy All-Stars" logo, but intact on the Boomerang streaming service on season 1), Popeye and Son, and the 1989 UK VHS release of Scooby-Doo and the Reluctant Werewolf (1988) from The Video Collection.
 * This was also seen on S3 episodes of The Jetsons from 1987, as well as the 1986 revival of Jonny Quest (which is also intact on HBO Max).
 * The 1988 version of this logo was also spotted on Yo, Yogi!, both when originally aired on NBC and on the Boomerang streaming service, followed by the 1989 variant of the 1988 Worldvision Enterprises logo (with the Spelling Entertainment byline).

Legacy: This logo has never reached the popularity of its predecessor, due to the rainbow trail being changed to look "looser". However, it's still a fairly well-remembered logo for people who grew up during this period or those watching Cartoon Network/Boomerang reruns of this era of TV programming.

9th Logo (November 8, 1986-1989)
Visuals: On a black background, a square appears and it spirals and forms a pattern that changes colors as the camera quickly zooms in to reveal a picture of Huckleberry Hound, Yogi Bear, Fred Flintstone, and Scooby-Doo, all standing together with big, goofy grins. Then, they disappear to reveal the 1979 H-B "Swirling Star" starting to animate like usual and then the star quickly zooms in with the letters "HB" in black. It then cuts to another scene with the words "HANNA BARBERA" stacked and zoomed up on the screen and it then zooms out while changing multiple colors before flashing and becoming a dark red.

Variant: On the HBTV tapes, the word "presents" fades in below the logo.

Technique: Early computer animation.

Audio: A "whoosh" sound followed by a synth-orchestra rendition of the first few notes of The Flintstones theme.

Audio Variant: The promo variant uses music from the promo and a male announcer saying, "Join the laughter, join the fun. Join the good times with the Hanna-Barbera Family. See these and all of your favorite Hanna-Barbera characters on Hanna-Barbera Home Video!"

Availability: Appears on HBTV VHS releases from Worldvision Home Video from 1986 to 1989, and at the end of a promo on the U.S. VHS release of Top Cat: T.C.'s Back in Town.

Legacy: The regular version of this logo has remained in obscurity until was uploaded online in recent years.

10th Logo (September 10, 1988-March 1, 1994)
Visuals: On a black background, "Hanna-Barbera" in its corporate font is written out in white. A large flash then appears, causing it to become a -gradient color.

Variants:
 * For the normal version, "PRESENTS" (in a white font, spaced out) may appear beneath the H-B text.
 * On the final two seasons of The Smurfs, the text reads "A Hanna-Barbera Production".
 * For the opening to Jetsons: The Movie, there is a series of CGI musical notes (the first four notes of the Jetsons theme), which turns around to reveal the cursive "Hanna-Barbera" logo and the words "A" and "PRODUCTION" fade in. Then, the camera zooms past the logo.
 * On season 2 of Tom & Jerry Kids, the corporate "Hanna-Barbera" logo is shown next to a B&W print version of the Swirling Star, and there is a dual credit with Turner Entertainment Co., the copyright owner of Tom and Jerry. It is positioned on a green background with a spotlight illuminating it, mimicking the red end card of the classic Tom and Jerry shorts. It was modified for the final two seasons, and read as "H-B Production Co." in the Brush Script font.
 * On the first season of the 1992 animated revival of The Addams Family, "H-B Production Co." is below a dark-colored "Hanna-Barbera" script logo, and the entire logo is surrounded by cobwebs on a black background.
 * On Fish Police, "Hanna-Barbera, Inc." is below the normal script logo (in a /yellow gradient color) on an underwater background.
 * On Monster in My Pocket: The Big Scream, there is a clip, then the Hanna-Barbera script appears after the monster raises its hat with its antenna, the script moving closer with "H-B PRODUCTION CO." with electric trails on the Hanna-Barbera script.

Technique: 2D animation. For some variants, just a still image. For the Jetsons: The Movie variant, a combination of CGI and 2D animation.

Audio: The closing theme of the show or none.

Audio Variants:
 * On Jetsons: The Movie, it's the opening theme of the film.
 * On the regular variant, the 1989 Hanna-Barbera Home Video theme is heard.

Availability:
 * The standard logo appears on the 1994 UK VHS releases of Top Cat: The Golden Fleecing, Hong Kong Phooey: Car Thieves, Yakky Doodle: Out of Luck, Duck and A Flintstone Family Christmas (1993), the 1995 UK VHS releases of The Flintstones: Dino's Two Tales and Yogi the Easter Bear (1994), the 1996 UK VHS releases of The Flintstones: Bumper Edition and Wacky Races: Bumper Edition, and the 1997 UK VHS release of The Perils of Penelope Pitstop: Bumper Edition, among others.
 * The "PRESENTS" version is seen on a few home video releases from Turner Home Entertainment after H-B's home video division was shut down, such as its release of Dastardly & Muttley.
 * It was also seen on the 1992 U.S. VHS re-release of Scooby-Doo and the Reluctant Werewolf (1988), and a late-2000s Boomerang rerun of Jonny's Golden Quest (the USA Network broadcast began with no logo).
 * It was also seen on a promo for The Galaxy of Hanna-Barbera Superstars on the end of the VHS, Hanna-Barbera: Festival of Fun.
 * The in-credit versions were seen on the final two seasons of The Smurfs, as well as on the opening credits of Jetsons: The Movie and seasons 2-4 of Tom and Jerry Kids (as a dual credit with Turner Entertainment Co. through its parent Turner Broadcasting, who would ironically end up purchasing Hanna-Barbera in 1991).
 * The latter has it plastered by the 8th logo on VHS releases, but is preserved on some DVD releases, including the complete series DVD, sometimes during the Tom and Jerry Marathon on Boomerang, and on Boomerang's streaming service.
 * The Addams Family variant was last seen when Boomerang reran the series every October, and also appears on VHS releases of the show.
 * When Cartoon Network UK last aired Fish Police, this variant was plastered with the "Hanna Barbera Inc." still CGI Swirling Star variant.
 * It can also still be seen on season 3 and 4 episodes on Tom and Jerry Kids on some DVD releases, including the German release of the complete series DVD and sometimes during the "Tom and Jerry Marathon" on Boomerang.
 * The Monster in My Pocket: The Big Scream variant was seen on said special.

11th Logo (The Flintstones 30th anniversary logo) (September 8, 1990-1991)
Images=

Videos=

Visuals: On a sky-blue background, Fred Flintstone, in a purple "caveman tuxedo", waves a 'magic cane' to make a box with the words "THE FIRST 30 YEARS" inside it appear next to him. He puts away the cane and proceeds to tap-dance in front of a purple baseball diamond-like shape. Above that in an arc is a sign reading "THE FLINTSTONES", with "THE" in a small black triangle above the arc. Below is the Hanna-Barbera script logo in.

Variant: One version (possibly only a print logo) used a background of animated TV static. It has Fred in a black caveman tuxedo over a red baseball diamond-like shape and the Hanna-Barbera script logo in yellow.

Trivia: This logo was created to celebrate the 30th anniversary of The Flintstones. Plus, the logo's design is made by Iwao Takamoto.

Technique: Traditional animation designed by Scott Shaw and animated by Mike Kazaleh.

Audio: The ending of the show's theme, or a synthesized instrumental of the Flintstones theme with a "zap" and a drumbeat.

Availability:
 * It was last seen on the first season of Tom and Jerry Kids on Boomerang, and can still be seen on the Boomerang streaming service's prints (which separate each of the segments into individual ones); however, VHS releases plaster it with the 10th logo.
 * It also appears (for some reason) on the segments "Catch That Mouse" and "Good Night Droopy" on the Boomerang service.
 * More shows that carried this logo are Wake, Rattle & Roll (with the synth theme), and the first season of Bill & Ted's Excellent Adventures, which can currently be seen on Hulu.
 * Gravedale High also used this, preceding the 1986-96 NBC Productions logo.

12th Logo (April 4, 1993-June 14, 2002)
Images=

Videos=

Visuals: On a colored background, there is a partial picture of a Hanna-Barbera character inside a geometric shape. Somewhere inside the picture is the "Hanna-Barbera" script logo.

Bylines:
 * 1993-1995: Bylineless
 * 1997-2001: "A Time Warner Company"
 * 2001-2002: "An AOL Time Warner Company"

Trivia: The second Dino variant debuted in the back side of the studio's 1993 calendar. Also, the Dexter variant debuted on the 1995 book The World of Hanna-Barbera and an advertisement.

Variants:
 * During the early days, the text "H-B PRODUCTION CO." is shown below the logo. This only applies to the Muttley version, as well as on Jonny's Golden Quest.
 * For the Atom Ant version, on a promo on the VHS of Dink the Little Dinosaur: Lights Out!, the text "Look out for these hilarious Hanna-Barbera cartoon characters on home video." fade in.
 * As noted above, each Hanna-Barbera produced original series for Cartoon Network from 1997 onward following the logo's resurrection starting with Cave Kids (used in February 1997) had this logo, always with the cartoons' star(s); the only exception was The Powerpuff Girls, which used an altered version of the 8th logo (though a "Portrait" variant was printed in a 1996 press coverage document). This not only included the regular half-hour series but one-off shorts, previously called What a Cartoon!, that now fell under the Cartoon Cartoons banner (which are now no longer rerun on TV). Thus, there are a large number of variations.
 * On some Series 1 episodes of Cow and Chicken, a differently styled byline is used. Appearing in an arc-like fashion below the logo are the words "Hanna-Barbera Cartoons, Inc. A Time Warner Company". Some episodes used it with the other byline as well, and the Cow and Chicken spin-off I Am Weasel used both bylines for all episodes. It's also rumoured to have been used on a few Dexter's Laboratory episodes as well, but this remains unconfirmed.
 * Some H-B cartoons from this period after Time Warner took over had some animation to include Cartoon Network's logo. The H-B logo would iris-out (1997-1999) or zoom out (1999-2001), and then a "shiny" version of Cartoon Network's 1992 logo would zoom in. Additional sound effects were used for this. Again, quickly dropped, as CN was putting a specially created network logo after Cartoon Cartoons. In some cases, there would be a quick fade out before the CN logo would appear. This was only used between mid 1998 and early 1999, but it was retained on Boomerang airings of Cow and Chicken, usually with the byline variant (it also appears on a few Dexter's Laboratory episodes, including the TV movie Ego Trip, where it appeared by zooming out of the top point in the "CGI Swirling Star", and at least one Johnny Bravo episode).
 * On the HD remaster of Scooby-Doo on Zombie Island (1998), the Scooby variant mentioned below has the Time Warner byline missing and the oval centered.
 * On all episodes of The What a Cartoon! Show, a headshot of Fred Flintstone looking upwards in a pale purple oval with a rose-pink script logo is plastered onto the lower right corner of the opening sequence after it briefly flies away at the start.

Custom Variants: This logo was customized for each show/TV movie produced by H-B during this era, and is available on only that specified show or TV movie:
 * 2 Stupid Dogs: There are two variants for this show: the opening had Little Dog in front of Big Dog laughing in a vertical rectangle, with the "Hanna-Barbera" text yellow and angled vertically on the right side (at 90-degrees clockwise), and "PRESENTS" is below the logo (all of this zooms in). This logo later zooms in to the show's opening. The closing has the rectangle raspberry-colored while "PRESENTS" is removed. Both variants use a white background. The end logo has multiple variations where the rectangle is positioned or rotated differently.
 * SWAT Kats: A grinning picture of one of the Kats inside a light blue oval (T-Bone, opening variant; for season 1, it cross-fades into the intro; for season 2, it flashes with energy, then fades into a shot of T-Bone, in his civilian identity, working on a car using a blow torch) or vertical rectangle (Razor, closing variant). A yellow-green “Hanna-Barbera” is seen, slanted and near the top. The background is either a dark blue-black gradient on the opening variant, or a dark blue-light blue gradient on the closing variant.
 * Muttley: A headshot of Muttley pops up and does his trademark snicker. The "Hanna-Barbera" script logo "writes" itself onscreen in copper letters. The background is black.
 * Jonny Quest:
 * The first variant has a headshot of Jonny Quest in a vertical rectangle. A greenish-blue "Hanna-Barbera" on an angle is near the top. The background is dark turquoise.
 * The second variant has a headshot of Jonny Quest (utilizing some sort of arm device) in a  oval. A  "Hanna-Barbera" script logo shining in copper letters is near the oval and slanted. The background is black.
 * The Addams Family: A headshot of Uncle Fester in a vertical pistachio-colored rectangle. A blue-purple "Hanna-Barbera" turned 90-degrees clockwise is on the right. This is on a purple background.
 * The Halloween Tree: A headshot of Mr. Moundshroud in a tomato-colored oval. A yellow "Hanna-Barbera" is near the bottom of the oval. The background is a gradient midnight blue (which seems vaguely similar to the one in the SWAT Kats opening variant).
 * Fred: There are four variants:
 * The first variant has a headshot of Fred Flintstone inside a purple rectangle. A "Hanna-Barbera" on angle is facing the top. The background is black.
 * The second variant, which is animated, has a headshot of Fred looking upward that appears inside a dark blue oval. A "Hanna-Barbera" wipes in over him, and as it wipes in, his pupils follow the words before moving down. The word "Presents", in a  color appears below the logo. A still version exists where the oval is  and the script is dark blue.
 * The third version after a rapidly shown montage of other characters, as it zooms out into an oval on a white background, shows Fred in a oval. The "Hanna-Barbera" script blurs in below the logo.
 * The fourth variant has a head shot of a happy Fred Flintstone inside of a purple oval on a black background, with the H-B script in light turquoise. The oval has a white border around it.
 * Santa Fred: A headshot of Fred, in Santa hat and outfit, inside a rectangle. The background inside the shape is, with snow against it. A yellow "Hanna-Barbera" slanted down is near the top. The background is either ,  or . For the  background variant, it features a  outline around the rectangle.
 * Droopy, Master Detective: A headshot of Droopy inside a solid rectangle. A yellow "Hanna-Barbera" is on the side. This is on a black-purple gradient background.
 * Dino: There are two variants:
 * The first variant has a headshot of Dino in a light blue rectangle. A yellow "Hanna-Barbera" is on the side. The background is.
 * The second variant has a headshot of Dino from The Flintstones inside an orange-yellow oval with the H-B script in light blue on a sky blue background. Under the logo is a copyright.
 * Yogi Bear: There are two variants:
 * The first variant has a headshot of a grinning Yogi Bear inside a rose bonbon rectangle. A tangerine-yellow "Hanna-Barbera" is on the side. This is on a solid background.
 * The second variant has a headshot of Yogi looking up inside a purple oval. A yellow "Hanna-Barbera" is shown titled. The background is black.
 * The Jetsons: A headshot of George Jetson with a huge smile inside a pistachio-colored rectangle. A rose bonbon "Hanna-Barbera" is on the side. The background is hot pink.
 * Atom Ant: As it was animated, a head shot of Atom Ant is shown flying. It later zooms out in an oval, and "Hanna-Barbera" blurs in over the oval. The background is white.
 * Dink the Little Dinosaur: A headshot of Dink the Little Dinosaur is shown on a pink oval. A purple "Hanna-Barbera" is on the side. The background is black.
 * Dexter's Laboratory (Season 2): A side profile of Dexter in a navy blue oval with the H-B script in medium red-violet. The background is white.
 * Cow and Chicken: Two variants: seasons 1 and 3 have Chicken at the left and Cow at the right in an oval with  H-B script (common on Boomerang); season 2 has Cow holding Chicken by his neck with apricot-colored script. The oval is also . The background is white.
 * Johnny Bravo (Seasons 1-3): Again, two variants: season 1 has Johnny in a purple oval with yellow H-B script; another features a close-up of Johnny in a sky blue oval with mint green H-B script. The first one debuted at the end of the third episode of the first season on July 21, 1997. The later one only appeared on two episodes of the second season. The background is white.
 * I Am Weasel: I.M. Weasel on the left giving a shy look and I.R. Baboon giving an annoyed/suspicious look on the right inside a jungle green oval with the H-B script in shocking pink. The background is white.
 * Kenny & the Chimp: Kenny (with an unhappy look on his face) and Chimp inside a pale turquoise oval with the H-B script in pumpkin orange. The background is white.
 * Foe Paws: Mama Mia smiling in-between Rolo with a surprised look and Vivian glaring inside a grasshopper-green rectangle with the H-B script in leyden blue. The background is white.
 * King Crab: Lieutenant Rock Shrimp with his frustrated face on the top inside a white rectangle with the H-B script in federal blue. The background is white.
 * Whatever Happened to Robot Jones? (Pilot): Robot Jones is tilted a bit inside a lime green rectangle with the H-B script in . The background is white. This was only seen on the pilot episode in 2000.
 * Thrillseekers: (from left to right) Joe, Otto and Ashley with excited looks on their faces inside a pale blue oval with the H-B script in dark turquoise. The background is white.
 * Uncle Gus: Uncle Gus standing in a ready-to-run pose inside a yellow vertical rectangle with the H-B script in white. The background is black, and the rectangle has a white border around it.
 * The Grim Adventures of Billy & Mandy (Pilot): A head shot of Grim in a black vertical rectangle with the H-B script in dark green. The background is white. Like the Robot Jones variant, it was only seen on the pilot episode.
 * Cave Kids: A head shot of Baby Pebbles Flintstone inside a sky blue oval with the H-B script in yellow. The background is white. Although the syndicated series aired on PBS in 1996, the show originally used the 1994 "Comedy All-Stars" logo before it was replaced with this logo in 1997.
 * Tom and Jerry ("The Mansion Cat" short): Head shots of Tom and Jerry inside a malachite box on a periwinkle background with the H-B script in flamingo pink. This one has a more 3-D look to it.
 * Scooby-Doo: A head shot of Scooby-Doo in a pinkish-red oval with the H-B script in . Like Uncle Gus and most promo versions, the background is black. This was used on the first four made-for-video Scooby-Doo movies produced by Warner Bros. Animation. There were no sound effects used. This was used from September 22, 1998 to October 9, 2001. Also, notably, this was one of the two versions to feature the AOL Time Warner byline from 2001, as seen at the end of Scooby-Doo and the Cyber Chase, the other one seen on the Dexter's Laboratory "Greatest Adventures" VHS.

Technique: Usually a still image, except for the opening 2 Stupid Dogs versions, as well as the Muttley and Atom Ant versions, the second variant of the Jonny Quest version, the green version of the Santa Fred variant, the SWAT Kats opening variant (season 2 only) and the Fred promo version from The Halloween Tree, which has 2D animation by Corey McPherson Nash under Big Blue Dot.

Audio: A montage of sounds from the company's extensive library of sound effects (which it had ironically begun to phase out of their cartoons around this time). It's different for each logo:
 * Muttley: There is Muttley's famous laugh, and as the Hanna-Barbera script logo is appearing, there is a small clarinet piece (an archival music cue from H-B's music library, written by Hoyt Curtin).
 * Dino and Fred: A rapid bongo drum take mixed with whirling slide whistles, followed by a "head take" sound that is interrupted halfway through.
 * Jonny Quest: The same rapid bongo drum take and a zing-out whistle.
 * Atom Ant: There is a wind noise and Atom Ant says "So long! Keep healthy everybody!", then giggles.
 * 1997-1999: A standard sound effect montage that was created for this logo, ending with H-B's weird "laughing" sound effect (performed by veteran H-B voice actor Daws Butler); the sound was first heard on the newer version of the 1996 Cartoon Network Studios logo, specifically the What-a-Cartoon! late 1996-produced shorts, such as Tales of Worm Paranoia, Zoonatiks, Snoots New Squat, Strange Things and newer prints of the two Malcolm and Melvin shorts produced in 1995 (the latter two had the 1994 All-Stars Comedy logo).
 * 1999-2002: The sound effect montage was switched to a different one that also incorporated classic Looney Tunes sound effects, possibly because of the Time Warner merger.
 * Robot Jones: There is various sounds of a chicken.

Audio Variants:
 * Sometimes the opening and closing themes of the show play over the logo instead.
 * On SWAT Kats, for the intro variants, it has a heavy metal tune (the beginning of the intro), along with electrical noises during the 2nd season; the first season has a deep bass note.
 * On the opening variant for 2 Stupid Dogs, a brief drumroll is heard, followed by alarm-like kazoos that begin the opening theme.
 * The extended version of the 1997 theme has a synthesized whoosh sound as the H-B oval irises out, and the sound effect of the paper carrier in The Flintstones throwing the stone newspaper onto Fred's head.
 * The "Comedy" sound effect montage from the next logo is heard over this logo at the end of the TV movie Scooby-Doo in Arabian Nights and a filmed print of the Cow & Chicken pilot from What a Cartoon!.
 * On Romanian dubs of Droopy Master Detective and on Scooby-Doo movies, the logo is silent.
 * On the Castilian Spanish dub of Dexter's Laboratory, the logo is also silent (likely audio from the 1st Cartoon Network Studios logo).

Availability: It was first seen on Jonny's Golden Quest, and was last seen in its original use on the final episode of SWAT Kats: The Radical Squadron, entitled "Unlikely Alloys", but it was revived when Time Warner bought out Turner in 1996. This was later seen as an in-credit logo on ''The What-a-Cartoon! Show, but was resurrected on the premiere of Cow & Chicken''. Overall, the logo was last seen on season 3 of Johnny Bravo.
 * Muttley: It was seen at the start of the 1994 TV special Scooby-Doo in Arabian Nights, which occasionally airs on Boomerang, but is cut out on most home video releases and on the Boomerang streaming service, respectively. Modern TV prints (i.e. an April 2023 Boomerang UK airing) also start without it. It also appears on the 1995 UK VHS releases of A Flintstones Christmas Carol (1994) and Richie Rich: Maltese Monkey, the 1996 UK VHS release of Scooby-Doo: Bumper Edition, the The Jetsons - The First Episodes Bulgarian VHS release, a Croatian VHS release of Midnight Patrol: Adventures in the Dream Zone, and at the start of the 1993 Flintstones special Hollyrock-a-Bye Baby, respectively.
 * 2 Stupid Dogs: Preserved on the 2 Stupid Dogs DVD set from Warner Archive.
 * Jonny Quest: Was last seen on seasons 4 and 5 of The New Adventures of Captain Planet when previously rerun on Boomerang. It was also seen on some prints of Jonny Quest from the early 1990s. The second version is seen on its first use, Jonny's Golden Quest, which was preserved on a Boomerang airing, as well as a 1993 promo for The Greatest Adventures of the Bible on the VHS release of Dink the Little Dinosaur.
 * SWAT Kats: Was last seen on reruns of said show on Boomerang, along with the VHS tapes and the DVDs from Warner Archive.
 * The Addams Family: Seen on original airings of the show on ABC and some VHS releases of the 1992 animated adaptation of said show, and also remains intact on some airings on Boomerang.
 * The Halloween Tree: Only seen on said special, which is available on VHS and DVD through Warner Archive, and also remains intact whenever Boomerang re-airs it.
 * Fred: Known to have appeared on the 1994 VHS release of The Flintstones: Wacky Inventions and may have also appeared on 1990s prints of said show. The fourth variant appears on a film master of The Chicken from Outer Space, but was later upgraded to the 1994 "Comedy All-Stars" version of the next logo.
 * Santa Fred: The green variant is seen on The Town Santa Forgot, the red variant on A Flintstone Family Christmas, while the blue variant is seen on A Flintstones Christmas Carol, all of which have been released on VHS and on the Boomerang streaming service, respectively. The blue variant also appears on the Tubi streaming print of the latter.
 * Droopy, Master Detective: Only seen on said show, but it can also be found on Boomerang's streaming service with the logo intact.
 * Dino: The first version was only seen at the end of the Flintstones special Hollyrock-a-Bye-Baby, which is available on VHS. The second version was only seen at the end of a film print of the Cow & Chicken pilot episode "No Smoking!" from The What-a-Cartoon Show.
 * Yogi Bear: Seen on Yogi the Easter Bear and Scooby-Doo's Arabian Nights, with the former airing on Boomerang every Easter and the latter airing on Boomerang occasionally; both have been released on VHS, DVD and on the Boomerang streaming service. It was also seen on some prints of Yogi Bear in the 1990s. The second variant is rare, having been seen on a 1994 UK Hanna-Barbera home video promo.
 * The Jetsons: Only seen on prints of said show from the early 1990s.
 * Atom Ant and Dink the Little Dinosaur: Seen on various home video promos from the 1990s, but both versions are seen on VHS releases of Dink the Little Dinosaur from Turner Home Entertainment.
 * Dexter's Laboratory: Appears on season 2 of said show on DVD and when rerun on Boomerang. It also plasters the Cartoon Network Studios logo on some airings of season 1 of said show.
 * Cow and Chicken: Both variants appear on said show which is available on DVD.
 * Johnny Bravo: The first variant appears on season 1 alongside its DVD release, and the second one appears on seasons 2-3, both of which air on Boomerang on some occasions, but not currently.
 * I Am Weasel: The show doesn't air often as a standalone show, and so this variant isn't easy to find. The Region 4 DVD release might contain it though.
 * Tom & Jerry: Only appears on the 2001 short "The Mansion Cat", which airs on Cartoon Network and Boomerang on rare occasions.
 * Scooby-Doo: Appears at the end of the first four of the made-for-video Scooby-Doo movies: Scooby-Doo on Zombie Island, Scooby-Doo and the Witches Ghost, Scooby-Doo and the Alien Invaders, and Scooby-Doo and the Cyber Chase, respectively.
 * Billy and Mandy: Only appears on the original pilot for The Grim Adventures of Billy and Mandy, which appears as a bonus on the season 1 DVD and was seen on recent CN airings (most notably on Cartoon Planet, where the logo was retained along with the original credits).
 * Promo variant with Atom Ant: Seen on the VHS of Dink the Little Dinosaur: Lights Out!.
 * Robot Jones: Only appeared on the original airing of the Whatever Happened to Robot Jones? pilot. Reruns of the pilot don't preserve this and it's unlikely that the show will ever air again on TV.
 * Uncle Gus: Only appeared on the first Uncle Gus short titled "For the Love of Monkeys" in 2000, while the second Uncle Gus short (titled "Not So Fast!") was produced by Red Sky Brand in 2001 when H-B closed the same year.
 * Cave Kids: If Cave Kids ever re-airs on Boomerang (probably as a standalone airing in June 2006) or appears on the Boomerang streaming service, a print with the "Comedy All-Stars" logo is very likely to appear instead of this one.
 * Rest of the variants: The rest of them were all one-shots that aired on What a Cartoon!, later known as The Cartoon Cartoon Show. They're most likely to never air again after The Cartoon Cartoon Show ended on Cartoon Network in 2003.

13th Logo (September 10, 1994-November 28, 1997)
Images=

Videos=

Visuals: On a blurry white background with several colorful, abstract shapes flying about, there is a clear square/oval that provides a "clear" view of the flying shapes; the square/oval has the Hanna-Barbera Script logo embossed in it at the top. Suddenly is some of Hanna-Barbera’s most famous stars running through the logo, as the square/oval begins to rotate. At the end, one of the stars ends up coming towards the logo, ending in a very extreme close-up of the star. A very small Turner byline (with Turner's own logo) appears in the lower right. Depending on the genre of the show, one of two similar but distinct variations of this logo are used: one for comedy shows, and the other for action shows. The stars, "music", and logo shape differ depending on the logo. Here are the stars for each version of the logo, in the order that they appear:


 * Comedy: The "Hanna-Barbera" script logo is and is put in a  rectangle:
 * 1) Fred Flintstone (sliding)
 * 2) Yogi Bear (grinning; this expression is actually from the 1959 short Show Biz Bear)
 * 3) Huckleberry Hound (falling from the top-left of the screen)
 * 4) Dino
 * 5) George Jetson (with a classic "what?" expression)
 * 6) Elroy Jetson (flying in a pod; the same animation seen in the Jetsons opening sequence)
 * 7) Barney Rubble (very hidden, you have to look close to find him)
 * 8) El Kabong (Quick Draw McGraw's Zorro-esque alter-ego)
 * 9) Scooby-Doo (who turns his head)
 * 10) Fred (zooms towards the logo; extreme close-up of his face after the explosion background appears quickly)


 * Action: The "Hanna-Barbera" script logo is sky blue and is put in a oval:
 * 1) Bandit (Jonny Quest's dog)
 * 2) Atom Ant
 * 3) Jonny Quest (in his trademark black shirt)
 * 4) Dr. Benton Quest (Jonny's dad)
 * 5) The Thing (yes, of the Fantastic Four; H-B did a series based on the Fantastic Four in 1967 in conjunction with Marvel Comics and WB continues to own the show even to this day, despite the TV/film franchise being generally under Disney)
 * 6) Zandor (firing an arrow)
 * 7) Space Ghost
 * 8) Birdman
 * Zok, the Laser Dragon creature from The Herculoids
 * 1) Jonny Quest with kung-fu like outfit (another zoom; like he's kicking into the camera)

Variants:
 * A still variant of the "Comedy" logo was also shown on the 1995 cartoon incarnation of Dumb and Dumber, with the small text "In association with" below. The New Line Television logo would follow.
 * Later episodes of The Real Adventures of Jonny Quest had this logo bylineless.
 * A version of the "Comedy All-Stars" logo has a variant with the Turner byline strangely blacked out.

Technique: A mix of CGI and digital ink-and-paint animation by Charlex.

Audio: Same as the last logo, but there's more than one used during the logo, and they are arranged to create a neat "tune". The music differs depending on the logo:
 * Comedy starts off with the weird horn sound effect from The Flintstones and The Jetsons, as we hear the sound usually heard as an H-B character starts to run away playing underneath. Then we hear a "boing" sound, several comical "fighting" sound effects, and finally the "kabong" sound of Quick Draw McGraw/El Kabong's guitar broken and dent over someone's head.
 * Action features a '60s-esque bass riff playing throughout. First, there is a screeching sound like a cartoon pterodactyl might make, a jet flying, an elephant trumpeting, and finally a loud, low-pitched gong.

Audio Variants:
 * On at least one airing of the Scooby-Doo, Where Are You! episode "A Night of Fright is No Delight" on Cartoon Network CEE (around 2013), the music from the 1968 "Zooming H-B" logo is heard over the "Action" logo.
 * On some episodes of The Addams Family (1992 series) aired on Boomerang Pan-Europe in Polish (such as "Little Big Thing/Little Bad Riding Hood/Metamorphosister"), the music from the short version of the 1987 Turner Entertainment Co. "CGI Globe" logo is heard over the "Comedy" logo. The most likely explanation is that for the respective episodes, the end credits soundtrack was sourced from a different master of the series that only had the Turner logo afterwards (and they forgot to adjust the audio of the logo).
 * On Cartoon Network CEE airings of The Scooby-Doo Show in Romanian, around 2010-2011, that had the credits air with a pushback ECP next bumper, the music from the end credits plays for a few seconds before cutting to the PAL-pitched 1979 "Swirling Star" music. This is because during the split-screen formatting and editing, the video footage of the 1995 European "Turner print" credits was used with the audio from the NTSC unrestored masters of the show, thus making the audio and video out-of-sync. A similar problem also occurred in airings with the Hungarian audiotrack, where the audio from the 1987 Turner "Globe" logo was plastered instead over the logo.
 * Most TV prints of the Scooby-Doo, Where Are You! episode "Never Ape an Ape Man" have the "Action" variant appearing with the audio from the "Comedy" version, most likely due to an editing error.
 * On the Top Cat episode "The $1,000,000 Derby" and The Flintstones episodes "Little Bamm-Bamm" and "The Hatrocks and the Gruesomes", the "Comedy" audio is in a lower pitch.
 * On a few shows the closing theme is used, such as on The Scooby-Doo Show, the 1975 Tom and Jerry Show, one episode of the 1992 Addams Family series and The Richie Rich Show. In all these cases, the logo plasters out other earlier ones entirely. The still/IAW variant used for Dumb and Dumber also had the end theme playing over it.
 * On The Flintstones episode "The Big Move", the 1979 "Swirling Star" sound was used over the "Comedy" version due to editing errors (as likely, the audio track of an 1980s unrestored master was used for that episode). However, MeTV airings of "The Big Move" (before the network was issued an updated print in 2020) had only the first half of the "Swirling Star" music before the "Comedy" version's soundtrack is joined in progress.
 * A similar audio error occurred on another MeTV airing of The Flintstones where the first half of the "Action" music before the "Comedy" version's soundtrack is joined in progress.
 * The same thing also happened on Boomerang Germany airings of The Jetsons, as the channel used the same intro and credits from the same episode on all showings (a common practice for CN and Boomerang overseas airings, for the matter). They used the audio footage from a pre-1995 unrestored print of a season 2 Jetsons episode which originally kept the 1983 version of the 1979 Swirling Star logo from that time, plastered over the video of another season 2 episode that was from the European Turner remaster and had the 1994 "Comedy" logo.
 * On some Romanian-dubbed episodes of The Perils of Penelope Pitstop on Boomerang CEE, the music from both the the 1968 "Zooming H-B" logo and the 1994 Warner Bros. Television theme plays over the whole "Comedy" logo. This is because the Romanian dub of the series (in 2012) was done using the stereo m/e track sourced from the DVD masters, which originally had this logo combo.

Availability: It was typically on "new" post-1994 prints of Hanna-Barbera's most popular shows, mostly 1960s shows that had an in-credit logo and Screen Gems logo/text.
 * It was first seen on SWAT Kats: The Radical Squadron, and was last seen on the Malcom and Melvin short "Babe He Calls Me".
 * In most cases of plastering, they match the right logo with the right show; the exceptions are the 1997 prints of Scooby-Doo, Where Are You! and The Scooby-Doo Show, which replace the "H-B Box" and "Swirling Star", or the "Rainbow" logo, with the "Action All-Stars" one.
 * However, when TBS aired Where Are You! in 1995, the "Comedy" logo was used.
 * Warner Bros. still used this logo to plaster older H-B logos on certain newer prints until around 2018, while newer HD restorations instead use the 2003-2021 WBTV logo when plastering anything over or alongside.
 * Turner Entertainment used the logo on many post-1995 TV remasters of H-B shows, aired by CN or Boomerang channels worldwide (on occasion these prints would appear on non-Turner networks), mainly for replacing already existing logos.
 * It can also sometimes either or not be followed by the 1987 Turner warp-speed "CGI Globe" logo, although CN/Boomerang airings often tend to cut it (though it is mainly kept on American broadcasts).
 * The "Comedy" variant was originally seen on 2 Stupid Dogs (season 2), Dumb and Dumber (1995 animated series; followed by the New Line Television logo), the 1995 Dr. Seuss special Daisy-Head Mayzie and at the end of cartoons produced in 1995 (with the exception of the short Awfully Lucky), airing from 1995 to 1997 on The What-a-Cartoon Show (later known as The Cartoon Cartoon Show).
 * The "Action" variant was first seen on SWAT Kats and the fifth season of The New Adventures of Captain Planet, and can be seen on the Warner Archive DVD release.
 * It also appeared at the end of The Real Adventures of Jonny Quest on Cartoon Network and on digital releases of the show.
 * The logos could generally be seen on Cartoon Network or Boomerang reruns of the "big hits", such as The Flintstones, The Jetsons (season 1 and at least three season 2 episodes), Top Cat, The Scooby-Doo Show and Scooby-Doo, Where Are Youǃ, be it in America or overseas. Could still pop up whenever these shows are rerun again on Boomerang in the USA or Tooncast in Latin America.
 * The appropriate variants can also be spotted on some DVD releases (as well as iTunes releases) of H-B cartoons, such as The Flintstones, The Jetsons, Top Cat, Wacky Races, Jonny Quest (both 1960s and 1980s series), Valley of the Dinosaurs, Moby Dick and Mighty Mightor, The Funky Phantom, Josie & the Pussycats, Josie & the Pussycats In Outer Space (on all but three episodes), Sky Commanders, and the 1973 version of The Addams Family.
 * It also was plastered over on ten episodes of The Flintstones Kids on the "The Flintstone Kids: Rockin' in Bedrock" 2-disc DVD release.
 * The logos also appeared on the Warner Archive releases of Thundarr the Barbarian and Dink The Little Dinosaur, which notably were produced by Ruby-Spears Enterprises and had no involvement from Hanna-Barbera; Warner Bros. generally label the pre-1991 R-S catalog as part of Hanna-Barbera for marketing purposes.
 * The "Comedy" variant also appeared on Boomerang reruns of the 1980-81 version of Scooby-Doo and Scrappy-Doo as well as the aforementioned show's episode "Alaskan King Coward" which appears on the Scooby-Doo! Holiday Collection and Scooby-Doo! Winter Wonderdog DVD releases which is then followed by the short version of the 1987 Turner "CGI Globe" logo, the Christmas special The Town Santa Forgot (preceded by the 11th logo; it is still rerun occasionally around the holiday season) and on the VHS release of the 1995 Dr. Seuss special Daisy-Head Mayzie (it is also present on the bonus feature DVD release of the classic Horton Hears a Who).
 * It also popped up on MeTV reruns of The Flintstones before the station was issued updated prints of that show in 2020.
 * The "Action" variant also plastered the 1986 "CGI Swirling Star" logo on Boomerang reruns of the 1986 version of Jonny Quest.
 * The "Comedy All-Stars" variant also plastered the 1983 version of the 1979 "Swirling Star" logo on a few remastered episodes of the 1980s version of The Jetsons (the ones that were not digitally-animated), and the 1969 logo on The Perils of Penelope Pitstop. All these instances also occurred when these series were rerun on Tooncast (in Latin America), until recently.
 * As for international airings, the "Comedy" variant was seen on Cartoon Network and Boomerang Pan-European prints of the 1992 animated revival of The Addams Family (season 1 and one episode from season 2), preceded by the 11th logo, as well as on Nova TV in Bulgaria.
 * The logo was also seen when Boomerang Europe aired series like Inch High Private Eye, The Perils of Penelope Pitstop, Josie and The Pussycats, the first two seasons of the 1980 Scooby-Doo and Scrappy-Doo series as well as at least one remastered episode (Turner European/PAL print) of Wacky Races.
 * Italian airings on Boomerang of the last of them also kept the logo on all the episodes.
 * The "Comedy" logo was also seen on CTC airings of The Tom and Jerry Show (1975) in Russia, as well as some Mexican broadcasts on Canal 5 (a few episodes instead had the extended 1987 Turner "CGI Globe" logo plastering it along with the short Turner variant), plus The Richie Rich Show on Planet Çocuk in Turkey.
 * It was also spotted on CN and Boomerang Europe airings of the feature film The Man Called Flintstone (1966) and a pan-regional DVD release of Yogi the Easter Bear (1994).
 * The two logos were also kept on the H-B episodes released on the "Cartoon Crack-Ups" VHS and DVD releases from Cartoon Network.
 * Both variants can still be seen on the Boomerang streaming service prints of The Flintstones, Top Cat, Jonny Quest (both 1960s and 1980s series), Wacky Races, Josie and The Pussycats, Josie and The Pussycats in Outer Space, The Richie Rich Show, Magilla Gorilla (the same prints used by HBO Max Latin America), Laff-A-Lympics and Flintstones Frolics (The Flintstones Comedy Show).
 * It was also sighted on Hulu prints of the 1978 Godzilla series, preceded by the 1974 "Rainbow H-B" small variant (and followed by the short 1987 "Turner Globe" logo).
 * The "Comedy" variant was plastered by the CITV ident on the October 3, 2003 airing of The Flintstones on ITV1's CITV block, in which the logo's theme plays over the ident after the show's end credits, due to an error.

Legacy: This logo is remembered by many, fondly (for its combination of 2D and CGI, as well as the concept of seeing many of Hanna-Barbera's beloved characters) or otherwise (because of the sound effects and loud gong on the Action variant, as well as the logo plastering over previous logos).

Final Note
After Scooby-Doo and the Cyber Chase was completed when William Hanna died, the animation studio was wholly folded into Warner Bros. Animation, while Cartoon Network Studios resurrected their name for their in-house productions that were made when it was a subsidiary of Hanna-Barbera. However, the Hanna-Barbera name was revived in 2017 with the next logo.

14th Logo (February 28, 2017-February 17, 2022)
Images=

Videos=

Visuals: Same concept as the 4th logo, except the colors are more vivid, the animation is smoother, and the last "HANNA-BARBERA" zooms at us a bit before morphing into an "HB" (in a similar style as the Taft-HB print logo). "HANNA-BARBERA CARTOONS" wipes in below.

Variant: On TV shows, the logo is shortened to the last few seconds, showing the finished "HB" logo and text, with the "HANNA-BARBERA" text still scrolling inside.

Technique: 2D computer animation.

Audio: The opening or closing theme of the film or show.

Availability:
 * So far, the long version has only been seen on the direct-to-video movie The Jetsons & WWE Robo WrestleMania!.
 * The short version also appears at the end of the Wacky Races reboot on the Boomerang streaming service, and at the end of Yabba Dabba Dinosaurs! on Boomerang internationally (and also later on HBO Max until 2022).
 * It does not appear on Jellystone! on HBO Max, or anything Scooby-Doo related from the studio (such as Scooby-Doo and Guess Who?, Happy Halloween, Scooby-Doo!, and Velma), as Warner generally classifies Scooby-Doo as a completely separate franchise from the rest of the H-B family.
