Corporation for Public Broadcasting

Background
The Corporation for Public Broadcasting (CPB) is a non-profit corporation created by the Public Broadcasting Act of 1967, signed into law by U.S. President Lyndon B. Johnson on November 7 of that year. It was created to provide partial federal funding for public broadcasting, initially collaborating with National Educational Television (NET) stations before starting their own private non-profit networks, Public Broadcasting Service (PBS) for television and National Public Radio (NPR) for radio.

1st Logo (1967-August 31, 2001)
Logo: We see the in-credit text "The Corporation for Public Broadcasting" or "Corporation for Public Broadcasting" during the sponsors or end credits of PBS shows. There are many font and color variations, some of which are written in all-caps.

Variant: On Mister Rogers' Neighborhood episodes from 1993-2001, the byline "A private corporation funded by the American people" (more commonly seen with the 7th logo and beyond) is added.

FX/SFX: None.

Music/Sounds/Voice-over: The text has no music of its own, but on several shows of the era it plays over the opening and closing themes. There are at least three voice-over variations:
 * "[PROGRAM NAME] is made possible by funding from the Corporation for Public Broadcasting."
 * "Additional funding provided by the Corporation for Public Broadcasting."
 * "Funding for this series was also provided by the Corporation for Public Broadcasting."

Availability:
 * Its variations have been preserved on DVDs, iTunes and Amazon Instant Video releases of PBS shows such as Sesame Street and The Electric Company. NOVA, Great Performances and 3-2-1 Classroom Contact will also likely have variations of this logo intact if reissued.
 * The last known show to use this logo was the series finale of Mister Rogers' Neighborhood in 2001. However, while Amazon Instant Video releases of 1970-75 episodes retain this logo, later episodes have all funding credits removed. This also appears on season 2 episodes of The American Experience.

Editor's Note: None.

2nd Logo (1969-1976)
2IpGa56k8_o VexRnwLdr5k

Logo: On a blue background we see a dark blue emblem consisting of the lowercase letters "c", "p" and "b" stacked together like a mixed-up jigsaw puzzle, and the text "serif" written below in a serif font.

Variants:
 * On black and white programs, the logo has a gray background with the emblem and the text in black.
 * An inverted variant of the black and white variant has been found.
 * There is a variant with a royal blue background and a white logo.

FX/SFX: None.

Music/Sounds/Voice-over: This logo has no music, but one of the following voice-overs is heard:
 * "[Nationwide] distribution of the preceding program is/was a service of the Corporation for Public Broadcasting."
 * "This program was made possible by a grant from the Corporation for Public Broadcasting."

Availability: Very rare.
 * Can be found at the end of episodes of Firing Line produced between 1970-1973, available for viewing on YouTube, as well as the Paley Center in New York and Los Angeles, and on YouTube. It was also known to be seen on a 1969 episode of Black Journal, The Violent Universe, and the NET special Crisis on Campus.
 * The royal blue background variant can be seen at the end of a 1972 episode of Firing Line titled "The Southern Imagination"; this episode is available on YouTube.
 * Several programs produced by NET starting in 1969 started getting grants from the CPB; a few of these programs can be found on the American Archive in Public Broadcasting website.

Editor's Note: The logo's abstract design is a throwback to mid-century abstract graphics.

3rd Logo (1975-1983)
Nickname: "CPB Curves"

Logo: Just a stylized "cpb" with the company name below. Sometimes, "The Program Fund" will appear above the company name.

FX/SFX: None.

Music/Sounds: Same as the 2nd logo.

Availability: Extremely rare. Seen on some episodes of Great Performances, including a trilogy of adaptations of works by Edith Wharton, and American Playhouse.

Editor's Note: None.

4th Logo (1983-March 5, 1990)
Nickname: "CPB in a Circle"

Logo: Just a circle with a stylized "CPB" cut into it on a blue (or black) background, with the phrase:

Garamond

underneath, in Garamond.

Variants:
 * A rare superimposed variant appears on Alive from Off Center, The MacNeil/Lehrer Newshour, and Jukebox Saturday Night.
 * A centered version of the circle appears without the text in the 1983 series Don't Look Now.

FX/SFX: None.

Music/Sounds/Voice-over: Same as the 2nd logo.

Availability: Ultra rare. Preserved on 1983-1985 Reading Rainbow tapes. This also appeared on pre-1987 episodes of The MacNeil/Lehrer NewsHour, Jukebox Saturday Night, season 1 episodes of The American Experience, and Eyes on the Prize.

Editor's Note: The logo bears a striking resemblance to the Chuck Barris logo and would continue to go up all the way until 2002.

5th Logo (October 1, 1984-November 29, 1987, September 1, 1991-July 1, 1992)
Nickname: "CPB in a Circle II"

Logo: Same as the fourth logo, but this time the background is a black/purple gradient. The whole thing also has a drop shadow.

Variants:
 * The first few programs that had this logo, including 1985 episodes of Reading Rainbow, omitted the drop shadow.
 * On some later programs, including season 1 episodes of Square One TV, the text was smaller, as the CPB circle took up half the screen.
 * 3-2-1 Classroom Contact used the aforementioned variation, but on a dark red background.
 * On Nuclear Legacy from 1986, the aforementioned variation took place on the 3rd logo's background.
 * On season 1-2 episodes of Degrassi Junior High, the CPB logo on a black background, is blue-violet with a magenta diagonal line sweeping by. Plus, all the text is set in the Haettenschwelier font for some reason.

FX/SFX: None.

Music/Sounds/Voice-over: Same as the 2nd logo, although a few episodes of Degrassi Junior High lacked the voice-over.

Availability: Ultra rare. Preserved on 1985-1987 Reading Rainbow tapes. This was also used on season 1 episodes of Square One TV, The Ring of Truth, 3-2-1 Classroom Contact, Degrassi Junior High, and Frontline, among others. Also seen on the 1992 rebroadcast of Huey Long, with the 1991 CPB logo following as part of the general funding credits for the rebroadcasts of this and three other Ken Burns classics at the time.

Editor's Note: None.

6th Logo (December 14, 1987-December 22, 1995)
Nicknames: "CPB in a Circle III", "CPB in Space"

Logo: The whole thing takes place on a space background with stars zooming past. The CPB logo is now in 3-D, and the circle is colored blue and white. First, we see it slowly rotating 90 degrees to the left. After it finishes rotating the words, the name pops up like this:

Serif

Variants:
 * Sometimes, a still version of the logo, with only the stars being animated, was used.
 * On Where in the World Is Carmen Sandiego?, the Earth is behind the whole thing, and on 1993-1996 episodes, the byline used in the 7th logo is seen below the text. On the series premiere, "The Taking of the Shrew", this only appeared at the start, with the standard version appearing at the end.
 * A variant with more stars can be seen on episodes of The MacNeil/Lehrer News Hour from August 14, 1989 to June 28, 1991.
 * An earlier variant, as seen on season 2-3 episodes of Square One TV, put this logo on a black/purple gradient background.
 * Some shows, like Great Performances, had the logo superimposed over a specialty backdrop.
 * The logo may also fade away to make room for the text "Viewers Like You", which contains the words "Viewers Like" (in a small font) with "you" sketched below in yellow script. This happened on many post-1988 shows. After being sketched, the yellow script glows in Where in the World Is Carmen Sandiego?.
 * On some shows, the "Viewers Like" words are in capitals.
 * On 1989 episodes of Frontline, the text is set in the Haettenschwelier font, just like the Degrassi Junior High episodes.

FX/SFX: The stars, and the occasional 90 degree rotation of the CPB circle from the left side of the screen; decent quality CGI.

Music/Sounds/Voice-over: Same as the 2nd logo, often with "...and by the (annual) financial support of viewers like you." or just simply "...and viewers like you.".

Availability: Rare.
 * Preserved on 1989-1991 Reading Rainbow tapes.
 * The animated variant also appeared on 1987-1991 episodes of The MacNeil/Lehrer NewsHour, Degrassi Junior High, WonderWorks, Great Performances, and Amigos.
 * The still variant also appeared on Where in the World Is Carmen Sandiego?, The Civil War, Long Ago and Far Away, American Playhouse, and American Masters.
 * The standard space background variant was last seen on The Dancing Man: Peg Leg Bates, which premiered on PBS stations on February 11, 1992.
 * On DVD, the logo can be seen at the beginning and end of the 1988 WonderWorks TV film, "Sweet Fifteen".

Editor's Note: This logo is a favorite to longtime PBS viewers as with new CGI effects.

7th Logo (July 1, 1991-2002, October 27, 2020)
Nicknames: "CPB in a Circle IV ","CGI CPB Circle", "Merging CPB Circles", "Sweeping Pink Lines"

Logo: Here are the main variants of this logo:
 * Version #1: On a textured cobalt blue/purple background with occasional thulian pink comets flying past, two circles slide in and form the CPB logo above the white text: Garamond At this point, a redesigned version of the CPB circle is now used, with a blue and lavender outline around it and in the letters. The font is also modified slightly, to ITC Garamond Light. After a few seconds, the text fades out as the logo splits into two CPB logos flying off to opposite sides of the screen so that the words "Viewers Like You" (in plain white plain serif text this time) appear in its place near the top, as more comets fly diagonally upward. For this version, the "Viewers Like You" text sometimes fades out earlier, so the background is shown for about one second before completely fading out.
 * Version #2: Starting on March 22, 1993, a new byline "A private corporation funded by the American people" in a condensed white Garamond font was added under the text. At that time, the text above was arranged centered and appears earlier, before the sweeping pink lines. Also, the CPB logo, smaller to make room for the byline, has a steel blue/opera mauve color scheme instead of the casual blue/lavender one, which is only used on still and superimposed variants.

Variants:
 * Like the 3rd logo, some shows superimpose the logo over a specialty backdrop, with NOVA being one example.
 * A still version is seen on some programs.
 * Some shows do not use the text "Viewers Like You".
 * Some shows just use the text, and not the circle.
 * Some shows, like 1990 episodes of Frontline, just use the circle, and not the text.
 * Some shows, like season 2 episodes of Wishbone, just use "Viewers Like You".
 * On shows which feature the still version of the CPB logo, the text "Viewers Like You" is dead center and often larger.
 * On some shows from 1991-1993, including episodes of American Experience and NOVA, the first variant of CPB logo has a brighter blue color scheme. This was often used for still or superimposed variants.
 * On 1991-1995 episodes of Sesame Street, the logo fades out (instead of the CPB logo splitting into two CPB logos) to make room for "PUBLIC TELEVISION STATIONS AND THEIR CONTRIBUTORS".
 * On some shows, particularly those produced by WGBH Boston, would feature a still version of the logo superimposed over a background unique to that show.
 * On 1997-1998 reruns of Barney & Friends episodes from seasons 1-3, the CPB logo is already formed for a few seconds, before it splits into two CPB circles, and reveals "Viewers Like You". This variant also lacks the sweeping lines. A rare superimposed version of this variant's animation, using the 1991-1993 graphics, was used on 1991-1992 episodes of Great Performances.
 * Starting on November 1, 1999, the text "Thank You" follows "Viewers Like You". This is often customized for the particular show; however, on programs that use this with the standard setting, the text uses a completely different font than had been used for eight years. The original font, however, was used on Wall Street Week episodes and Not Done: Women Remaking America.
 * On The Charlie Horse Music Pizza, the logo is a solid ultramarine color with "The Corporation for Public Broadcasting" and the usual byline below it in the Ad-Lib font, all against a stylized musical-oriented background.
 * On Club Connect, there are more sweeping pink lines, the two big circles move slower, and the text appears after the logo (in brighter colors) is formed. Unlike most uses of the logo, this particular variant has an accompanying soundtrack. A silent version of this variant was also used on season 1 episodes of Dragon Tales.
 * On 1998-2001 episodes of NOVA, a bold Century Gothic font was used. On at least one or two episodes, the text is not bold.
 * Ghostwriter used an animated sky background with two pinwheels forming the CPB circle. In later episodes from 1993-1995, the background was replaced with an animated aquamarine background with jacks.
 * Sometimes, it was superimposed in the credits along with the PBS logo (the P-Heads on top of the "PBS" letters, like the 3rd and 6th PBS logos) in yellow.
 * On Kratt's Creatures and The Living Edens, the CPB circle is transparent.
 * On 1995-1998 episodes of Sesame Street, the whole text is bigger and written in cursive, and the logo is shown on the top left of the screen. The background takes place behind a green curtain.
 * On 1999-2002 episodes of Reading Rainbow, the logo takes place on a nighttime background with swirling rainbows flying around.
 * On 1993 episodes of The Puzzle Place, the logo (with byline) is still, then, a set of CGI puzzle pieces (the same ones that are the background for the other variant for this show) fly towards the logo, fit together, and then fly off the screen, revealing the SCE Corp funding tag. On 1996 episodes, the Puzzle Place logo is shown, then the flashing puzzle pieces in the background disappear one by one to reveal the CPB background, and as the PP logo fades out, the standard CPB animation plays.
 * On The Prize: The Epic Quest for Oil, Money, and Power and The Longest Hatred, both the CPB logo and "Viewers Like You" are shown at the same time.
 * On John Glenn: American Hero, the "Viewers Like You" tag is completely static, except for fades at both ends.
 * On pledge drive programming such as The Internet Show, The Judds' Farewell Concert, and The Kennedy Center 25th Anniversary Celebration, the "Viewers Like You" tag used a blurry, multi-colored background. This was also seen on the Sesame Street specials Elmo Saves Christmas and Elmopalooza.

FX/SFX: The lines and the circles sliding. Great animation.

Music/Sounds/Voice-over: Same as the 6th logo. The voice-overs are the same as the first logo.
 * Sesame Street episodes from 1991-1992 used the famous "Funky Chimes" as background music, while episodes from 1992-1995 used a hip-hop instrumental based on the Sesame Street theme. Episodes from 1995-2001 used a jazzy version of the afromentioned theme.

Music/Sounds/Voice-over Variants:
 * On all Sesame Street episodes with this logo from 1991-1995, the announcer (Gordon [Roscoe Orman]) says "Funding for this program was provided in part by the Corporation for Public Broadcasting... and by public television stations and their contributors." In 1991-1992 only, the "Funky Chimes" played under the voiceover; starting in November 1992, the music was a rearrangement of the '90s closing theme.
 * On 1995-1998 episodes of Sesame Street, a kid (Gabi [Gabriela Rose Reagan]) says "Funding for Sesame Street was provided in part by the Corporation for Public Broadcasting... and by public television stations and their contributors." A brass-driven, jazzy rearrangement of the show's theme music played under the voiceover.
 * On 1999-2000 episodes of Dragon Tales, the announcer says "Dragon Tales is funded in part, by a grant from the Corporation for Public Broadcasting, through funds from the US Department of Education.
 * On 1998-2000 episodes of Sesame Street, Gordon says this time "Funding for Sesame Street is provided by the annual financial support of PBS Viewers Like You." The music was the same as before.
 * Sometimes, for example, on 1989-1991 episodes of NOVA, 1989-1999 episodes of Frontline, and 1989-1996 episodes of Nightly Business Report (the latter only at the end), the announcer says, "...the [annual] financial support of viewers like you", even though "Public Television Viewers" is shown on the screen.
 * Starting on November 1, 1999, the "viewers like you" spiel is changed to "Contributions to your PBS station from viewers like you (or, in the case of such programs as Sesame Street, Masterpiece, and PBS Arts Fall Festival, "...and viewers like you.") Thank you."
 * The spiel varies from show to show. For example, on the revivals of Zoom, the Zoomers shout "Thanks!" instead, and the announcer for Mister Rogers' Neighborhood utters "We thank you." Some early programs originally broadcast during this period, including Not for Ourselves Alone, omit the "Thank you" entirely, and Frontline used the wording "financial support from PBS Viewers Like You" for about a decade after.
 * On pre-1997 episodes of Bill Nye the Science Guy, a small portion of a random hard rock/alternative song (e.g. "The Star-Spangled Banner" as performed by Jimi Hendrix) played under the voiceover.

Availability: Pretty common.
 * It has been preserved on reruns of 1991-2000 PBS programs, even when the current PBS logo is plastered over a previous logo. Also preserved on PBS Home Video tapes and DVDs of the era.
 * The byline variant, which first appeared on the Shining Time Station episode "Becky Makes a Wish", is much easier to find and can be spotted, for example, at the end of at least one or two episodes on a few of The Magic School Bus DVD releases, the KidVision VHS of The Magic School Bus episodes "Butterfly and the Bog Beast" (released as "Butterflies!") and "Out of This World" (this does not appear on the KidVision releases of "Taking Flight" and A Magic School Bus Halloween, the latter which was made out to look like a simple double-episode videocassette of "Going Batty" and "Inside the Haunted House" per the slipcover), and on some PolyGram tapes of Wishbone that end with the Big Feats! logo, including "Salty Dog" (on such Wishbone tapes, this will inevitably be followed by the 1993 PBS Kids logo). It also assists the plastering of the previous funding credits for post-1994 prints of David Macaulay's Castle and Cathedral.
 * This logo was last seen on Dragon Tales reruns on PBS Kids Sprout and can be also found on the DVD releases of the show.
 * On DVD, the standard animation of the 1993 logo can also be found with the Ken Burns' documentaries Baseball and Thomas Jefferson, and the Rick Sebak documentary, An Ice Cream Show.
 * The solo "Viewers Like You" variant made a surprise appearance on Not Done: Women Remaking America, broadcast on October 27, 2020.

Editor's Note: Much like the 6th logo, this is a favorite to most PBS viewers.

8th Logo (November 9, 1998-2001)
Logo: On the same background as the 7th PBS logo (replete with the walking men silhouettes), we see the CPB print logo, in black, centered on the screen. This time, no text or byline is shown. The logo is then usually followed by the "Viewers Like You" and "Thank You" disclaimers, which are often custom-made for the particular show, or else uses the standard font introduced in 1999.

Variants:
 * Though this is one of the few logos to lack the text or byline, another variant of the regular logo exists with the byline from before, along with the URL, "cpb.org", added in 2001. The byline has two different arrangements, with one arrangement being in two different fonts.
 * The superimposed variants during this era, including on Cooking with Master Chefs, In Julia's Kitchen with Master Chefs, and Baking with Julia broadcasts at the time, often have the CPB circle in white.
 * On In the Mix, the CPB logo is only followed by the "Thank You" disclaimer.
 * On early programs, "Viewers Like You" is styled differently, and is not followed by "Thank You".

FX/SFX: The background.

Music/Sounds/Voice-over: Availability: Very rare. In fact, it's probably the one of rarest of the CPB logos.
 * An extended version of the 1998 PBS logo's music, albeit entirely on guitar. The music is also used on 2000-2004 episodes of Scientific American Frontiers, using the "Viewers Like You" disclaimer without the CPB logo. On some programs, music relating to the program is used instead.
 * For voice-overs, an announcer either says, "This program is made possible by the Corporation for Public Broadcasting" or "and by the Corporation for Public Broadcasting". This is often followed by the updated "viewers like you" and "thank you" spiel from the 7th logo.
 * It may appear on PBS programs from 2000-2001 if your station has older prints. Also seen on a few PBS Home Video tapes of the era.
 * The early "Viewers Like You" variant can be seen on Digital TV: A Cringely Crash Course and Fiesta in the Sky and appeared mainly on DTV programming. This also plastered the previous logo and sponsor tags - for Braun and Farberware - on broadcasts of Cooking with Master Chefs from 1999 to 2010, and it did the same for the previous logo and sponsor tags - for E&J Gallo Winery and Farberware - on broadcasts of In Julia's Kitchen with Master Chefs from the same period.

Editor's Note: None.

9th Logo (2000-2015)
Nickname: "CPB in a Square"

Logo: On an aqua background, blue and white dots appear in the center of the screen and pulse out, while streaks run through it. The rings then form the CPB logo, redesigned again with smoother text and is now in a square. The "p" and "b" are connected to the edge of the square. The white then fades out inside the text and 4 streaks run along the edges. The same byline appears underneath in all capitals, but with "CPB.ORG" at the end in blue, which is wiped with a streak.
 * For the Viewers Like You variant, the same dots appear across the screen, vertically centered, and blue and white rings provide the transition from the CPB slide to the "Viewers Like You" slide, and the process repeats itself for the transition from the "Viewers Like You" to the "Thank You" slide. Both the "Viewers Like You" and "Thank You" slides have the letters moving closer to the center.

Variants:
 * On Life 360, the whole thing is on a black background.
 * On several shows, a still version is superimposed over the credits of that show.
 * Some shows, like Nature, just use "Viewers Like You."
 * On American Experience, the logo is in gold.
 * On PBS Kids shows, such as Clifford the Big Red Dog, Reading Rainbow, Sesame Street, and Dragon Tales, there is a certain background with two halves of different colors. On the bottom half, there is a kid's head, and on the top half, there is a thought bubble, transforming from two different objects to another kid's head. For the CPB logo, the top half is red, and the bottom half is yellow, and a girl's head is placed on the bottom right. Sometimes, on 2002-2004 episodes on Sesame Street, the PBS Kids circular logo is shown before the CPB logo appears.
 * There is another PBS Kids variant that lacks the heads and thought bubbles, while the logos are centered on the screen. Also, the CPB logo appears on the second screen, after the US Department of Education logo is shown. On Dragon Tales, there is an additional third screen with "Viewers Like You" centered on the red top half with the girl's head shown without the thought bubble.
 * Some shows, like Between the Lions, do not use "Viewers Like You."
 * On Reading Rainbow and some prints of Dragon Tales, the blue dots bounce off the bottom of the screen, then onto the middle and form the CPB logo. The URL slides in to the top left of the screen. Then, the byline (which is now in a straight line, in blue, and not all capitalized) fades in at the bottom and forms a smile. Sometimes, the text may not smile.
 * On 2001-2007 episodes of Great Performances, the logo looks more like a rectangle, apparently due to some sloppy digital manipulation.
 * Some pledge drive specials, even a Sesame Street/Elmo's World special, use only the "Viewers Like You" half of the standard variant.
 * A alternate version of the RR variant exists, where instead it has the same animation as the normal variant

FX/SFX: The blue dots forming the CPB logo.

Music/Sounds/Voice-over: The music consists of a futuristic synth tune as the dots appear, followed by a woodwind note as the CPB logo wipes in. This is followed by an updated version of the 1996 PBS logo's music, performed on brass. (This version is also used for the actual PBS logo on Beyond the Color Line.) The voiceovers are the same as the 7th logo.

Music/Sounds Variants:
 * The Reading Rainbow variant has a weird Moog synth tune with kids claiming, "WHOA!", followed by a muffled "mmmm..." when the byline forms a smile.
 * The solo "Viewers Like You" variant is not known to have any music.
 * The logo may also have no music.

Availability:
 * May appear on PBS programs from 2000-2015 if your station has older prints. Also seen on a few PBS Home Video tapes of the era.
 * While the superimposed variants are more common, the blue dots version is close to being rare, only being known to appear on home video on America Rebuilds: A Year at Ground Zero, although the Reading Rainbow variant can be easily found on current DVD releases of the show.
 * The PBS Kids variants can currently be found on Super Why!, Clifford the Big Red Dog, while Sesame Street continued to carry the centered version of the CPB logo until 2014. This is plastered by the 12th logo on current broadcast prints of Jazz, though most episodes retain this logo on their streaming counterparts.

Editor's Note: It should be said that despite the shape change, the "cpb" text looks even more like the Chuck Barris logo.

10th Logo (September 24, 2002-November 2019)
Nickname: "CPB in a Square II"

Logo: On a blue/purple/red ethereal background with silhouettes of random people doing various things, the CPB logo wipes in horizontally (first with the dots, then the text), and the byline from the 9th logo appears. During all of this, the PBS P-Head (the 1989 PBS logo's size) is shown in the background, moving up and down, left and right, etc.

Variants:
 * A widescreen variant is introduced in 2005. In this version, the byline and URL are slightly altered.
 * Starting in 2007, the background and the logo were graphically enhanced, with the silver tinted CPB logo with a shine instead of white. The byline and URL were altered in the same silver and shine color as on the CPB square logo. The wiping in of the logo is quicker. It's then followed by the letters "Viewers Like You" and "Thank You" in the same silver and shine color as seen on the CPB logo.
 * On several shows like Washington Week (where this specific animation persisted until at least 2011) and Sid the Science Kid (which features only the CPB square wiping in), the animation (or simply a still version) of the logo is superimposed.
 * On A Place of Our Own, the logo is black.
 * On current episodes of NOVA and 2010 episodes of Fetch! with Ruff Ruffman, the logo features a royal blue line sweeping by.
 * On 2000s and 2010s episodes of Frontline, "Viewers Like You" and "Thank You" are both shown at the very start of the funding credits, immediately before this logo.
 * Sometimes, the company name is shown. This was seen on The National Parks: America's Best Idea, Independent Lens, and later episodes of American Experience, among other programs.

FX/SFX: The wiping in of the CPB logo.

Music/Sounds/Voice-over: Several variations of the 2002 PBS logo's music have been used so far. The voiceover is the same as the 8th logo.

Music/Sounds/Voice-over Variants:
 * When the CPB logo is shown by itself, either the program's custom funding credits music or the music played on the "Mother and Daughter" variant of the 2002 PBS logo is used.
 * Due to the aforementioned unusual funding arrangement, the voiceover on Frontline goes "Frontline is made possible by contributions to your PBS station from Viewers Like You–thank you!–and by the Corporation for Public Broadcasting."

Availability: Common.
 * Should be preserved on 2002-2019 PBS programs funded by CPB if your station has older prints. Its last appearance was on a 2019 episode of Wild Kratts.
 * The fully-animated version continued to appear superimposed on WETA programs such as Washington Week and In Performance at the White House until at least 2013.
 * The "Viewers Like You" portion surprisingly reappeared on recent rebroadcasts of The Adirondacks.

Editor's Note: None.

11th Logo (March 24, 2010-November 2019)
Nicknames: "CPB in a Square III", "Colorful CPB"

Logo: On the 2009 PBS logo's bubble background, the CPB logo in white appears via bubbles forming the square while the text zooms out, and the byline from the 9th and 10th logos appears. Then, "Viewers Like You" wipes in left to right, in the PBS Explorer font (similar in style to Interstate). "Viewers Like" is white, and "You" is yellow within a dark rectangle. After a few seconds, "Viewers Like" wipes out right to left and is replaced by "Thank", with "You" shifting to the left to ensure centering just as quickly.

Variants:
 * On Washington Week (on which it started appearing as early as 2011) and some other programs, including PBS NewsHour beginning with the July 20, 2015 edition, the third season of Finding Your Roots, In Performance at the White House, Library of Congress Gershwin Prize, The Civil War, and Jazz, the whole animation is superimposed.
 * Programs not funded by CPB which use this variant, mainly British programs, include Call the Midwife, PBS Arts Fall Festival, Pioneers of Television, and the respective first seasons of Vicious and The Great British Baking Show (and also the third season of the latter).
 * Starting on October 7, 2013, the company name, aligned to the left and in ITC Avant Garde Gothic, appears below the square, and the byline, in the same font, is a single line of text, without the URL.
 * However, Washington Week continued to use the earlier variant until June 26, 2015, though it made surprise appearances at the end of some editions from November 6, 2015 to January or February 2016, and also on America After Charleston.
 * On Ready Jet Go!, the 2015 variant's byline is in a more digital font.
 * Sometimes, as seen on Arthur and American Masters, the 2015 variant appears inside of a white rectangle.
 * On Tavis Smiley, the CPB logo didn't appear. Instead, the bubble background was shown animating by itself before the "Viewers Like You/Thank You" animation played.
 * On other programs that used this animation with the standard background but weren't funded by CPB, snippets of the Guitarist, Doodling Pad, Generations, Spacesuit, and Stargazing variants of the 2009 PBS logo were shown before transitioning to the standard animation with the bubble background, around the point where the "Viewers Like You/Thank You" animation starts playing. This was actually the first variant of this logo, and premiered a few months before the standard CPB/VLY version.
 * On Summer, Surf & Beach Music We Love, the above variant instead wipes to a custom background, with "VIEWERS LIKE YOU" appearing on an airplane banner and "THANK YOU" appearing directly underneath.
 * On Josh Groban: Bridges in Concert from Madison Square Garden, the solo "Viewers Like YOU" variant is zoomed in heavily for some reason.
 * On The Contenders: 16 for '16 and The Vietnam War, the 2015 variant has the byline on two lines once more.
 * On occasion, the original variant has been shown against a black background.

FX/SFX: The wiping in of the CPB logo.

Music/Sounds/Voice-over: A variation of the 2009 PBS logo's music. The voiceover is the same as in the previous logo.

Music/Sounds/Voice-over Variants:
 * As with the previous logo, Frontline used a variant reversing the CPB and "Viewers Like You" credits.
 * NOVA, in referring to public television viewers, had its shortened announcement say, "...and by PBS viewers like you. Thank you." Some episodes, however, used the standard full voiceover until the 2015 variant was introduced.
 * On most programs funded by public television viewers but not CPB, including pledge drive specials and pre-2014 DVD and Blu-ray releases of Masterpiece, the "Viewers Like You" voiceover said, "Explore new worlds and new ideas through programs like this, made available for everyone through contributions to your PBS station from viewers like you. Thank you."
 * Tavis Smiley had the program theme play over this.

Availability: Common.
 * The orange variant is the most common and even plasters over the 8th logo on In Julia's Kitchen with Master Chefs, the 10th logo on Carrier, and the 9th logo on Jazz.
 * The magenta variant is typically used for superimposed variants, including on Finding Your Roots.
 * The blue variant appeared on PBS NewsHour until July 17, 2015, and is also used for the superimposed variant on most editions of Washington Week beginning on June 29, 2015. This premiered just a few months after its solo "Viewers Like You" counterpart, and is still used as part of the current CPB/Viewers Like You combo even after the next logo entered use.
