1st Logo (April 15, 1994-)
jD5PAaJfib4 fePDexeu0JU

Nickname: "The Checkerboard"

Logo: We see the 1992-2004 logo of Cartoon Network (which is basically the words, "CARTOON NETWORK" written on a black and white checkerboard with the white letters on black squares and the black letters on the white squares), superimposed on the screen. Usually, the copyright stamp and/or the Turner/(AOL) Time Warner byline is seen below.

Variants:
 * This logo would come after the 1997 Hanna-Barbera logo from some season 1 & season 2 episodes of Johnny Bravo, season 3 episodes of Cow & Chicken, several season 2 episodes of Dexter's Laboratory, Dexter's Laboratory: Ego Trip (after the 1998 H-B logo), and sometimes season 1 episodes of The Powerpuff Girls and the season 2 episode "Slave the Day"/"Los Dos Mojos" with this logo zooming-in on a white background. As it stops, the Service Mark symbol (SM) appears on the center right side of the logo.
 * On some very early What-a-Cartoon Show shorts, the logo is up against a purple-white gradient background with text in black reading "HOME OF THE TOP TOON STARS" below. On some airings (particularly on Boomerang), it would appear after the Hanna-Barbera "Comedy All-Stars" or Cartoon Network Studios logos before it was plastered by them.
 * On later What-a-Cartoon Show shorts, the logo is up against a black background with a white box around it with no byline. This was later removed from all airings.
 * On Big Bag, the logo is in 3D against a blue background with no byline.
 * There is another bylineless variant seen on very early Cartoon Network airings of Cartoon Planet where the logo is on a black background.
 * On The Popeye Show anthology series, the logo is on a red background.
 * On Harvey Birdman, Attorney at Law, the logo appears against Harvey's power symbol (the stylized winged Sun). 5 black bars shoot out of the right of the screen and expand, covering the logo.
 * On season 1 of The Amazing World of Gumball, the logo is in-credit below the Dandelion Studios logo.
 * In exceptional cases, an in-credit text was used.
 * On some episodes of Space Ghost Coast to Coast, the logo is very tiny. It may either be inverted, on a white background, or on a black background, depending on the episode.
 * On Toonheads, the logo is on a black background with "A Time Warner Company" below the logo. The copyright stamp is seen below.
 * On some episodes of Sealab 2021, there is a typo in the copyright notice, where it says "All Right Reserved" instead of "All Rights Reserved".
 * On early episodes of Sealab 2021, it's the same as the Toonheads variant, but the logo is much smaller. There is another variant in which the colors of the logo are inverted.
 * On the Sealab 2021 episode "Murphy Murph and the Feng Shui Bunch", Master Shake from Aqua Teen Hunger Force tries to break the Cartoon Network Productions logo, after he broke the 70/30 Productions and Williams Street logos, but fails.
 * There is a version with "Co-produced by" in white above the logo.
 * On the Sealab 2021 episode "Bizarro", the Bizarro version of Quinn jumps on the logo several times, causing the logo to lower down, while he shouts "I'm helping! I'm helping!".
 * On The Moxy & Flea Show: Abducted and Johnny Bravo Goes to Bollywood, the logo is seen without byline or copyright.
 * On Brak Presents the Brak Show Starring Brak, the logo is on a paper taped to the background with the copyright shown.
 * On the world premiere of The Moxy Show, the logo is in 3D with copyright, and also in that logo, Moxy is seen dancing under a spotlight.
 * On the Space Ghost Coast to Coast episode "Girl Hair", the logo is moving, while it also contains fire.
 * On the Brak Show episode "The Eye", the eye is floating in front of the Cartoon Network logo.
 * On the Sealab 2021 episode "Neptunati", the logo is placed near the bottom of the screen, then Zombie Cat (with a rainbow trail behind him) falls on the logo and says "Zombie Cat loves you".
 * On the Sealab 2021 episode "Let 'Em Eat Corn", the logo appears as normal, then we cut to a living room setting with the logo on a TV screen. Two men on a couch say a few lines, then a dresser "wakes up", looks around, then closes back up.

FX/SFX: None. For the variant, the logo zooms in rapidly.

Music/Sounds: Usually the closing theme of the show. In other cases, it's silent.
 * Other times, it carries the 2nd half of the long 1997 Hanna-Barbera Cartoons theme. The zooming variant uses a "whoosh" sound with other assorted SFX.
 * On The Moxy & Flea Show: Abducted, Flea mutters quietly, "There's no such thing as monkey underwear".
 * On The Popeye Show, a fragment from "Popeye the Sailor", the very first cartoon, is heard.
 * For the Toonheads variant, a woman says "Watch these and other great cartoons on the Acme Hour, right here on Cartoon Network".
 * For the Sealab 2021 "Let 'Em Eat Corn" variant, the second guy on the couch says "Man, this damn show!". The first guy on the couch then says "Dude, it keeps on getting lame." The second guy then says "Random a** confusing bulls-" before getting interrupted by the dresser waking up, to which the second guy in response says "No. Bad dresser."
 * The Brak Show 's "The Eye" variant has a cranky voice saying "Hey, hey, hey. I float like a floating eye, sting like a floating eye. Oh yeah!"
 * On SGC2C, a soundbite from the preceding episode.
 * On "Bobcat", we hear Marky Ramone scatting.
 * On "Punch", Space Ghost says "Magenta. Now that's a silly word."
 * The Space Ghost Coast To Coast "Girl Hair" variant has random gibberish in the start. Then, Zorak says "No, no, no. It's got to be heated! Heated up!" Fire crackling is heard throughout.
 * On earlier airings of Cartoon Planet, it's a musical box jingle.

Availability: Common.
 * Seen on some Cartoon Cartoons of the era and Adult Swim shows, such as Space Ghost Coast to Coast, Harvey Birdman, Attorney At Law, Sealab 2021 and The Brak Show, as well on various animated shorts aired occasionally on Adult Swim, the 2007 revival of George of the Jungle, and season 1 of The Amazing World of Gumball.
 * The 3-D variant should be preserved on VHS tapes of Big Bag.
 * The black bylineless version is extinct; it was seen on programs like later What-a-Cartoon Show! shorts and Cartoon Network airings of Cartoon Planet during said show's run on TBS.
 * The zoom-in variant is seen on seasons 1 & 2 of Johnny Bravo, season 3 of Cow & Chicken, several season 2 episodes of Dexter's Laboratory, Dexter's Laboratory: Ego Trip, and sometimes, season 1 episodes of The Powerpuff Girls on Boomerang. Also seen on on the short The Moxy & Flea Show: Abducted.
 * The purple-white version has oddly recently shown up on airings of the early What-a-Cartoon shorts on Boomerang (these are later prints, as the What-a-Cartoon logo and music at the beginning and end are removed (a version of the Cartoon Cartoon music plays instead). On pre-1996 airings of Cartoon Planet, the logo appears directly after a still version of the Ghost Planet Industries logo. Oddly enough, on some later airings of Cartoon Planet, this logo makes an appearance immediately after the next logo below. The same situation occurred on Space Ghost: Coast to Coast, where it appears directly after the credits and then the normal logos appear. Retained on iTunes prints of Space Ghost: Coast to Coast.

Editor's Note: None.

2nd Logo (Space Ghost Coast to Coast Custom Logo) (1995-1998)
Nicknames: "Jack-in-the-Box CN Logo", "CN-in-the-Box", "Surprise!", "The Checkerboard II"

Logo: On a pink background with the 1992-2004 Cartoon Network logo and a yellow zig-zag line on the bottom moving, an object pops out of the logo. It has a pinkish/purplish and blue zig-zagged stick holding a red oval with the word "PRODUCTIONS" on it. Then, sticks and eyeballs pop out of the CN logo, with the eyeballs each leaving behind a dotted trail. The zig-zagged stick wobbles through the remainder.

Trivia:
 * This logo briefly appeared on the SGC2C episode "Untitled".
 * The Cartoon Planet and "Zorak" audio variants can be heard at the beginning and end of Space Ghost's Musical Barb-B-Que (1997) and Space Ghost's Surf & Turf (1998).

FX/SFX: The jack-in-the-box's animation. This was animated by Stephen W. Brandt in-house using Mac and Flame platforms.

Variant: An alternate version of this logo (looking less hand-drawn) appears on Stephen W. Brandt's broadcast design reel. The zig-zagged stick is also yellow and blue.

Music/Sounds: The logo has its own music (which varies on SGC2C, though only one variant was used on Cartoon Planet), with different sound effects to accent the pop-up of "PRODUCTIONS" and the sticks and eyeballs flying out. Most of the time on SGC2C, a soundbite from the previous episode or a clip of the show's music (composed by the late Sony Sharrock and Eddie Horst) would be used:
 * An accordion and weird, distorted sounds.
 * A 5-note tune and a frog croaking twice.
 * A wobble/sizzle sound with metallic chimes.
 * An 8-note xylophone/piano tune.
 * Andy Merrill saying "stupid" six times.
 * Space Ghost saying "I don't know."
 * A deck of cards being shuffled.
 * A slide whistle rising and a boing, used on "Gilligan", "Sharrock", and "Banjo".

Availability: Rare, as most SGC2C episodes only have the previous logo. Appears on DVDs and digital prints of Space Ghost: Coast to Coast; said prints of certain Season 1 episodes have this logo. It also appeared on Cartoon Planet (long gone from TV, but segments from it appear on DVDs of SGC2C and The Brak Show) after it moved from TBS to Cartoon Network in 1996; earlier CN airings have the previous logo. One of the logo's earliest appearances was in February 1996, after the SGC2C episode "$20.01" aired. It was long rumored to have appeared on What a Cartoon!. The alternate variant appears on Stephen W. Brandt's broadcast design reel.

Editor's Note: The logo looks cool, but it may unnerve some. This logo was also only used on Space Ghost: Coast to Coast and Cartoon Planet.

3rd Logo (October 22, 1999-November 10, 2016; January 21, 2019)
Nicknames: "The Ripple", "The Cartoon Cartoons Logo", "Classic CN", "The Checkerboard III"

Logo: On a black background, we see the 1992-2004 Cartoon Network logo in the middle of the screen. Appearing from behind the logo are the turquoise circles used in the 1998 Cartoon Cartoons logo, which stop after the theme is played. The byline "A Time Warner Company/An AOL Time Warner Company" can be seen below the logo, and to the center-right of it is the Service Mark/Trade Mark ("SM/TM") symbol.

Trivia: This logo is based on an intro for Cartoon Cartoons, a block that ran on Cartoon Network from 1997 to 2003. It is also in the same style as the Hanna-Barbera variation of the 1st logo (for the Service Mark symbol variant (October 22, 1999 to late 2014)) with the differences are the 1992-2004 CN logo is in 2D and not shining, and the SM symbol and parent company byline are in white text.

Variants:
 * From 2001-2003, due to the AOL merger with Time Warner (Turner Broadcasting System's parent company, where Turner serves as the parent company of Cartoon Network), the byline reads "An AOL Time Warner Company".
 * In late 2005, the circles appearing behind the 1992-2004 CN logo are faster, and when aired in 4:3, the logo is larger.
 * Starting on late 2006, however, the speed of circles and size of a logo mentioned before will play regardless of what aspect ratio is used.
 * From October 28, 2014 to November 10, 2016 (the last two years of usage of the 1999-2016 Ripple logo), the Trade Mark symbol ("TM") is now used instead of the originally-used Service Mark ("SM") symbol. This version of the Ripple endtag also appears on the credits error of Cartoon Network airing of the Steven Universe episode "Change Your Mind" on January 21, 2019.
 * Sometimes, after the animation finishes, the logo stays still for a couple seconds before cutting to black.
 * On DreamWorks Dragons, the logo is black, still and superimposed on the background used in the closing credits.
 * On The Powerpuff Girls (1998 series) episode "Seed No Evil/City of Clipsville", it had a very poorly edited blacked out byline (presumably because of the byline on the CN Studios logo). However, judging with the black bar underneath the 1992-2004 CN logo that can be seen when the circles appear behind the logo stretches below the "N" of the "Network" at the left and "K" at the right, this on-screen logo uses the AOL Time Warner byline variant.
 * On the Codename: Kids Next Door TV movie Operation: I.N.T.E.R.V.I.E.W.S., the logo is still (likely because it was the very last episode of the series).
 * On The Powerpuff Girls Rule!, the logo is squished.
 * On the Castilian Spanish dub of Re-Animated, the logo has a copyright stamp on the bottom.
 * A short version exists. This was spotted after the AKA Cartoon Inc. logo on some season 2 episodes of Ed, Edd, n' Eddy on DVD, and season 3 episodes on iTunes.

FX/SFX: The blue circle outlines rippling.

Music/Sounds: The last 7 notes of the "Cartoon Cartoons" ID theme. The themes are high-toned if aired or normal tone for DVD releases in PAL-formatted countries or, with the exceptions of Southeast Asia through both Cartoon Network (including its Philippines feed) and HBO GO (for most cases); unlike on Nickelodeon (some of the shows are in PAL; and its closing logo was edited out recently) and Disney Channel (all of its programming are in PAL), this logo mostly plays in NTSC in Southeast Asia, despite all of the Southeast Asian countries (except the Philippines) are PAL-formatted.

Music/Sounds Variants:
 * On Australian broadcasts of season 3 of Chowder, the entire logo plays in a low tone.
 * On DreamWorks Dragons, Transformers: Animated, George of the Jungle and Re-Animated, the ending theme plays over the logo.
 * Sometimes, it’s silent.
 * On the short version, only the last 4 notes of the music are used.

Availability: Common, outside of US television and DVDs; otherwise, uncommon. First seen on the Johnny Bravo episode "Galaxy Boy/Damien’s Day Out/Noir Johnny".
 * This logo was used on episodes of respective Cartoon Network shows (as well as its movies) that were produced between October 22, 1999 and November 10, 2016. However, on recent U.S. airings of Cartoon Network shows, this logo is edited out, but is preserved on HBO Max and other streaming platforms (such as HBO GO in selected countries like Singapore, Indonesia, Malaysia, Thailand, Vietnam, the Philippines, and Netflix globally).
 * Survives on some episodes of the 2001 revival of Dexter's Laboratory when reran on Boomerang.
 * It also appeared directly under the split-screen credits of Courage the Cowardly Dog on Cartoon Network, plastering the Stretch Films logo. Plus, it was seen on several 1999 episodes of Johnny Bravo and episodes of Samurai Jack on Boomerang.
 * This logo is a lot more common outside the U.S., as it is seen at pretty much the end of all Cartoon Network-produced shows.
 * Strangely, it is seen on Regular Show episodes on iTunes, plastering the Cartoon Network Studios logo, as well as episodes of the show seen on demand and on the CN app.
 * This logo can be seen on every post-1999 Cartoon Network show on DVD (such as season box sets of The Powerpuff Girls [original], Samurai Jack, Adventure Time and Regular Show, as well as various Cartoon Network compilation DVDs).
 * Also seen on the sneak peek, on demand, and CN app versions of Uncle Grandpa.
 * The variant with the Service Mark (SM) symbol is seen on episodes of CN shows, films, and shorts that were produced between October 22, 1999 and late 2014 (like The Powerpuff Girls (1998-2005), Ben 10 Classic, Ben 10: Alien Force, Ben 10: Ultimate Alien, most episodes of Ben 10: Omniverse (episodes 1–77; 80, from The More Things Change: Part 1 to Malgax Attacks and A New Dawn), some episodes of Adventure Time, Steven Universe, Uncle Grandpa, Regular Show, etc.) while the one with the Trade Mark (TM) symbol is seen on episodes, films, and shorts that were produced between October 28, 2014 and November 10, 2016 (such as the 2016 Powerpuff Girls reboot, We Bare Bears, episodes 78 and 79 (The Most Dangerous Show and The End of an Era) of Ben 10: Omniverse, episodes 1–22; 24–29 (from Waterfilter to Bright Lights, Black Hearts and All Wet to The Beast Inside) of the 2016 Ben 10 reboot, etc.).
 * The last Cartoon Network short to use this logo is Lasso & Comet, a Cartoon Network Asia short, while the last Cartoon Network original series to use this logo is Ben 10 2016 reboot.
 * Strangely appeared in 2019 on the premiere of the Steven Universe episode "Change Your Mind", despite the fact that the show switched to the 9th logo since late season 4. This is because it used the credits for "We Need to Talk" episode (which was produced in 2015 according to the credits) instead of the credits for "Change Your Mind".

Editor's Note: This logo was definitely a product of its time, as the overall theme of the logo provided people with a rush of memories who grew up with the "Powerhouse" era. This logo was used for almost 20 years.

4th Logo (May 30, 2000-October 23, 2001)
BeO5O_qu6ws 8lTU75wsnwM

Nicknames: "Dee Dee!", "A Cartoon Network Presentation", "The Checkerboard IV"

Logo: TBA

Variant: TBA

FX/SFX: Cel animation.

Music/Sounds: TBA

Music/Sounds Variant: TBA

Availability: Extremely rare. It can be found on most Powerpuff Girls VHS tapes.

Editor's Note: None.

5th Logo (Adult Swim Custom Logo) (May 7, 2001-2012)
Nicknames: "The CN Skull", "The Checkerboard Skull", "The Skull Logo", "Skull!"

Logo: We see a skull and crossbones on a white background with the 1992-2004 Cartoon Network logo as its teeth. The copyright stamp and the Time Warner byline is below. The skull was created by Linda Simensky.

Trivia: This logo first appeared on the Space Ghost: Coast to Coast season 7 episodes "Kentucky Nightmare", which originally aired a few months before Adult Swim started broadcasting on May 7. It appeared again on the episode "Justice Hole", which aired seven days after Adult Swim launched. This logo was also featured in an AS bump from 2010, specifically, the 2008 variant (and it is where you can see the change on the skull's teeth or the checkerboard logo there) was the one that was used.

Variants:
 * Starting in 2008, it appeared in 2D, and the logo is much bigger overall. If you look closely, the checkerboard teeth are also changed. Instead of using the actual corporate 1992-2004 logo, a custom variant is used with the letters in a hand-written and messy style.
 * Sometimes appears without the copyright stamp.
 * On seasons 2-6 episodes of Squidbillies, the logo flashes to a cartoon squid skull for a split-second before changing back into normal.
 * On the Space Ghost: Coast to Coast episode "Flipmode", the logo is in static.
 * On Eagleheart, it superimposed on the copyright credits with the IATSE and Teamsters logos.
 * On the Xavier: Renegade Angel episode "Bloodcorn", the logo is red.
 * A sepia variant exists.

FX/SFX: None.

Music/Sounds: Just Matt Maiellaro (writer of Space Ghost Coast to Coast and co-creator of Aqua Teen Hunger Force) saying "Skull!". On some Space Ghost episodes and other shows, the closing theme accompanies it.

Music/Sounds Variants:
 * Occasionally, Maiellaro saying "Skull!" will be time-stretched as if it was running through a granular synthesizer. This variant first appeared in 2006 and was used in tandem with the original variant until this variant replaced it around 2008 (with the exception of Squidbillies).
 * On seasons 2-6 episodes of Squidbillies, the audio is replaced with a different character (varies depending on each episode) saying "Skull." or other words or phrases.
 * On the Aqua Teen Hunger Force episode "Sirens", Sirens sing "SKULL" instead of Maiellaro yelling "SKUUUUUUUUUUULLL!!!!!".
 * On the Aqua Teen Hunger Force episode "Dusty Gozongas", the audio is replaced with a character from earlier in the episode saying "Yes!"
 * On the Aqua Teen Hunger Force episode "A PE Christmas", the audio is replaced with a door bell sound.
 * On early live action Adult Swim shows (mainly Delocated and a few others), the logo is silent.
 * On the Xavier: Renegade Angel episode "Bloodcorn", the audio is muffled with a sound of a liquid of blood pouring.
 * On season 1 episodes of Superjail!, the last hammer strike from the Williams Street logo is heard.
 * On the ninth and final season of Space Ghost: Coast to Coast, Maiellaro saying "Skull." in a low tone. However, a different variant exists on "Idlewild South" and "Dreams" where he alternately shouts "Skull!" in a high tone.
 * On the Lucy, the Daughter of the Devil episode "Temptasia", a different voice shouts "SKULL-L-L-L-L-L-L-L-L-L!!!!!".

Availability: Common.
 * Can be seen directly after the Williams Street logo on many Adult Swim shows, such as Space Ghost: Coast to Coast from "Kentucky Nightmare" to "Unfinished POS", Aqua Teen Hunger Force, Robot Chicken, 12 oz. Mouse, Metalocalypse, and Sealab 2021 episodes after "Shrabster" among others. It is also seen on IGPX: Immortal Grand Prix.
 * On UK broadcasts of Adult Swim shows (mainly Robot Chicken and a couple of others), the logo's contrast has been turned up to the point where the logo is barely viewable, and only stays on screen for, in most cases, not even a second. This could be accounted to the fact that the Adult Swim lineup in the UK was broadcast on FX, and then Fox, and not Cartoon Network. From Robot Chicken: Star Wars onward, the logo is unobscured and appears fully.
 * It is plastered out of current adultswim.com prints of shows like 12 oz. Mouse along with the Williams Street logo being shortened to one hammer strike instead of two.

Editor's Note: Well-known by many viewers who watched Adult Swim in its early days, despite it usually appearing for half a second.

6th Logo (Hi Hi Puffy AmiYumi Custom Logo) (November 19, 2004-June 27, 2006)
Nicknames: "The Japanese Cartoon Network Logo", "J-CN"

Logo: On a white background, we see the 2004-2010 Cartoon Network logo in Japanese lettering, which later changes to the English letter initials "CN". Underneath the letters is "CARTOON NETWORK" in its usual font and the byline "A Time Warner Company" (in the same font as the 3rd logo).

FX/SFX: The letters changing from Japanese to English.

Music/Sounds: A wooden flute theme, followed by people shouting "CN!" in Japanese.

Availability: Rare. It was only seen on Hi Hi Puffy AmiYumi, and is preserved on DVD releases.

Editor's Note: A funny send up, and rather cute too.

7th Logo (November 5, 2005-August 26, 2006)
Nicknames: "In-credit Cartoon Network Logo", "Produced with Bandai Entertainment and Production I.G", "The IGPX Logo"

Logo: On a black background, the 2004-2010 Cartoon Network logo is in the end credits with the logo for Production I.G and Bandai Entertainment, for Immortal Grand Prix, along with copyright stamps.

FX/SFX: None.

Music/Sounds: TBA

Availability: Rare. It was only seen on Immortal Grand Prix.

Editor's Note: None.

8th Logo (September 6, 2010-)
Nicknames: "Cartoon Network Shorts", "CN Print"

Logo: Basically an end tag featuring the 2010 Cartoon Network logo, except the copyright information is shown.

Variants:
 * On Bill and Tony, a white background is used, plus the copyright notice is shown as "© 2015 TURNER BROADCASTING SYSTEM ASIA PACIFIC, INC.". The current variant only includes the logo, making it similar to the end of a Cartoon Network bumper or promo.
 * On Series 2 of Animal Control, the logo's text is absent.
 * Starting in 2018, a still, in-credit CN logo started being used for Cartoon Network's co-produced shows.

FX/SFX: The blocks sticking and spinning. None for the in-credit variant.

Music/Sounds:
 * From 2013 to 2014, the same Cartoon Cartoons jingle from the 1999-2016 logo was used. On The Fog of Courage, the tone of the jingle is slightly lower.
 * On some episodes of Bill and Tony and Series 2 of Animal Control, the swoosh sound effect is used.
 * On newer episodes of Bill and Tony, the current 4-note jingle is used with the conjunction of the current logo's sound effect.
 * On the in-credit variant, the ending theme of the show is heard.

Availability:
 * Animated variant: This is only used on animated shorts that are airing in Asia. The Cartoon Cartoons variant can be found in The Fog of Courage (which hasn't been aired in the United States yet) and Series 1 of Animal Control. The textless variant can be found on Series 2 of Animal Control. The white background variant can be found on Bill and Tony, as well as the current one.
 * In-credit variant: Currently used on Cartoon Network co-productions such as Total DramaRama, Bakugan: Battle Planet and Power Players. This logo is sometimes removed on non-US prints of these shows.

Editor's Note: None.

9th Logo (November 10, 2016-April 2019; March 6-April 9, 2021)
Nicknames: "The Exploding Blocks", "The CN Explosion", "Generic CN", "The Checkerboard V"

Logo: On a blue background, a black square (the C square) rolls like a dice and a white square (the N square) dashes in and they merge. When they merge, they explode and form the 2010 version of the Cartoon Network Checkerboard logo. The background will then change from blue to white once this happens.

FX/SFX: The explosion and the boxes merging to the logo.

Music/Sounds: A retro 4 note theme of the 2010 CN jingle.

Music/Sounds Variants: On the 2016 Ben 10 reboot episode "Recipe for Disaster", the Cartoon Cartoons jingle from the 1999-2016 Ripple logo plays over the logo. This is likely an error. It can also happen on some international Cartoon Network channels that air this logo.

Availability: Uncommon.
 * Debuted on Regular Show since "The Key to the Universe" onwards. For some reason, it also appears on digital prints (and some international prints, such as British versions) of season 5 from Samurai Jack, even though the show aired on Adult Swim and was co-produced by Williams Street (probably since Samurai Jack originally debuted on CN itself (specifically, the first 4 seasons all premiered and aired on CN) and thus this logo was used).
 * It also appeared on Welcome to My Life, a Cartoon Network short, despite the fact that the short was produced in 2015, one year before the introduction of this logo.
 * Starting on June 15, 2018 upon changing the name of Turner Broadcasting System's (Cartoon Network's parent company) parent Time Warner to WarnerMedia due to AT&T acquisition of the company, the copyright information at the end of credits of any CN original mentions Cartoon Network Studios instead of Cartoon Network. Despite this, this logo was used until April 2019, because Cartoon Network Productions serves as the network's distribution arm while Cartoon Network Studios produces shows for the network.
 * Since April 2019, this endtag is no longer used on episodes of Cartoon Network original series, pilots, and films that were produced, released, and distributed in the United States due to the dissolution of Turner Broadcasting System, Cartoon Network's parent company, which removed all references to Turner Broadcasting including this division (with the last CN original series to use the Exploding Blocks endtag or in general, Cartoon Network Productions logo, is Victor and Valentino and the first CN original series to not use the said endtag is Mao Mao: Heroes of Pure Heart, while the first CN movie not to use the CNP logo is Steven Universe: The Movie). As a result, they simply end with the Cartoon Network Studios logo.
 * Surprisingly, this logo started to make a comeback on Elliott from Earth, which first aired in Africa and in the UK on March 6, 2021. Most likely because the show started production in 2018, when this logo was still used.

Editor's Note: The explosion leading up to the revamped version of the checkerboard logo makes it a more suitable and worthy successor to the 1999-2016 Ripple logo.
