PBS Kids Go!

Background
PBS Kids Go! was a block of programming created by PBS in 2004 to appeal to kids ages 6-13 as opposed to the 2-5 target audience of PBS Kids. In 2013, the block was discontinued.

1st Logo (October 11, 2004-September 3, 2007)
Logo/ID: Kids (wearing blue shirts) do a certain activity to reveal the PBS Kids Go! logo in a certain way.

Variants:
 * Stairs: A boy jumps on a few colored platforms. As he steps on them, multiple boxes emerge out of a nearby building, with more kids inside of them. At the end, the PBS Kids Go! logo emerges out of the building, as a Boston Terrier comes out of another box and barks at the logo.
 * A variant of the stairs logo which excludes the URL.
 * Button: A boy steps on a button four times, causing a girl in the background to rise up on a  platform. When she gets to the top, she presses another button on the side of a nearby building, uncovering a screen containing the PBS Kids Go! logo.
 * A variant of the button logo which excludes the URL.
 * Echo: A girl yells "Go!" into a tube. The camera pans quickly, revealing a boy standing on the other side of the tube. He then yells "Go!" to another tube above, and the camera pans again. As another kid on the other side hears the "Go!", he pulls a lever on the side of a  box, causing a panel containing the PBS Kids Go! logo to slide up. A boy above the platform then yells "Go!".
 * Tubes: We see a boy sitting on a platform, in an upside-down view. Two tubes, one and one white, emerge onto the screen, the former sliding in various different directions, and the latter only sliding up. An  button then slides out of the  tube, and a boy emerges out of it to press the button. A hammer then slides out of the right side of the  tube, with the circular side containing the PBS Kids Go! logo. A girl then comes out of the white tube and yells "Go!"
 * Cropped 16:9 versions for DragonflyTV exist.

Technique: Stop-motion computer animation. Designed by Head Gear Animation.

Music/Sounds: A percussion theme, ending with an acoustic guitar and a 4-note whistling tune, then a group of kids shouting "Go!".

Music/Sounds Variant: At the end of one episode of DragonflyTV, an audio variant of the button logo which uses the music of the stairs logo. This variant can be seen in this video. It is possible however, that this is an error in the episode print and not intentional.

Availability: The logo used to be very common, but has since become rare to see on TV due to most of the shows that used it either being repackaged to use different logos or removed from PBS entirely. Currently, all four logos can be seen at the end of Maya & Miguel, which still airs on the kids subchannel of the PBS station KLCS, located in Los Angeles. The logos can also be seen on Prime Video prints of ''Fetch! with Ruff Ruffman''. This logo can be found on the Cyberchase DVD "EcoHaven CSE".

2nd Logo (September 3, 2007-January 19, 2009)
Logo/ID: Same as the last logo, but the kids are now in full-motion, additionally the environment is fully CGI instead of stop-motion. It should be noted that the URL simply fades in at the corner of the screen this time.

Variants:
 * Balloon: Two girls jump on an enlarged pump, pushing air into a balloon with the PBS Kids Go! logo on it. The balloon then comes out of the stand and flies up in the air.
 * Bicycle: A girl rides on a bicycle. She rings a bell with the PBS Kids Go! logo, causing the blocks in the area to move out of the girl's way. As she continues riding, the PBS Kids Go! logo is seen on the ground, which then pops out to the music.
 * Bicycle Cube: A boy is riding a bike. He gets off, and the bike disintegrates and compresses itself inside a small cube. As the cube gets smaller to the point where the boy picks it up within his hand, the PBS Kids Go! logo is seen on the side.
 * Bubbles: A girl is turning a wheel, revealing a water faucet pouring many bubbles into the air. One of the bubbles has the PBS Kids Go! logo. The girl is then seen riding on said bubble.
 * Email: A girl comes up to another, saying something in her ear. The second girl then pushes a button on her phone, sending a message to a boy. He pushes a button on his laptop, opening his inbox and revealing a message with the PBS Kids Go! logo on it. The camera zooms up close to the logo.
 * Falling Blocks: Large cubes are balancing themselves high above the ground, with segments of the PBS Kids Go! logo on it. The camera moves to the bottom, revealing a partial PBS Kids Go! block structure. As kids on the bottom jump, the other blocks fall in place.
 * Hopscotch: A girl plays hopscotch, with the squares lighting up as she steps on them. When she steps on the semicircle, a trapdoor opens up revealing the PBS Kids Go! logo, and two other girls that pop out. Another trapdoor opens in the distance, with a boy jumping out. They all say "Go!".
 * Laptop: A boy presses a button on a laptop, revealing a wire extending out of it. The wire moves throughout a path and eventually extends up a building with a Boston Terrier adjacent to it. Atop the building is an block with an outlined PBS Kids Go! logo on it. As the wire reaches the block, the logo turns fully  and pops out.
 * Time Lapse: A group of kids build a nine-cube arrangement of the PBS Kids Go! logo, in time-lapse fashion. Once complete, a girl comes out of the left side and shouts "Go!"
 * Wheel: Two girls turn a wheel, rotating the camera and turning the girls upside-down. In the background we see many PBS Kids Go! logos floating down to the bottom of the screen.
 * Dancing (2008-2010): There were two versions.
 * The camera pans through a large block-filled environment, with a large block toward the back containing the PBS Kids Go! logo. On the smaller blocks are various kids and show characters (such as Arthur Read from Arthur, Ruff Ruffman from Fetch!, and Captain Huggy Face from WordGirl), all dancing.
 * Two girls, as well as DW Read, do a cartwheel. Then, a group of kids synchronize to a foot stomp. The camera then pans, in a similar fashion to the above variant. The ident ends with a boy pointing at the camera.

Technique: Live-action combined with CGI. Designed by Jeffery Boortz.

Music/Sounds: Same as the 1st logo.

Music/Sounds Variant: On the "Time Lapse" variant, building noises are heard along with some chatter. At the end, percussion music plays with a girl saying "Go!".

Availability: Extremely rare, unlike the last logo. All shows that used this logo have either removed it or have stopped airing on PBS entirely. However, certain stations air their own recordings of episodes instead of prints nationally aired by PBS, which sometimes results in this logo being seen, but few stations still air their own recordings. If they do, they are usually from an era before or after this one. The last known time this logo was seen in full live was in late 2018. This logo can also be seen on iTunes prints of Arthur and a Prime Video print of one ''Fetch! with Ruff Ruffman episode, as well as a pbskids.org print of one episode of Arthur'' in late 2021/early 2022. In addition, PBS station KLCS-DT2 often shows a split second of the soccer or jumping logo variants before Maya & Miguel. The jumping variant is also lost except for a split second of it recorded from a Maya & Miguel airing.

Legacy: This tends to be the set of logos people remember the most from PBS Kids Go!, along with the next logo.

3rd Logo (January 19, 2009-October 7, 2013)
Logo/ID: Same as before, however in a brighter environment. The URL is now once again integrated into the logo's elements.

Variants:
 * Balance: A girl jumps onto a platform, lowering it while also causing another one to rise up, with another kid emerging from the bottom. Seeing the kid is not high enough, she motions the other girl on the side to come to the platform. As she does that, the other white platform rises up extremely high, causing the other kid to go off screen. The PBS Kids Go! logo is seen on the side of the white platform.
 * Binoculars: We see a boy looking into a pair of binoculars. He then moves his sight towards a girl, who points somewhere below. As the boy moves downward, his field of vision is completely blocked by another boy's eyes. They then laugh, as the PBS Kids Go! logo is seen in the background.
 * Block Dam: A boy and a girl are standing across from each other, with a rectangular object preventing green cubes from coming down a chute. The girl then releases the object, making the cubes fall down, move toward another section with two more boys standing on the sides, and finally onto a large reservoir shaped like the PBS Kids Go! logo, with a girl watching from above.
 * Compass: A boy and a girl run onto an empty space. The girl then pulls out a compass, with the north sign reading "GO!". Ahead in the distance, pieces of the PBS Kids Go! logo rotate together towards the girls.
 * Elevator Up: A girl sees an lever on the side of a  building. The girl pulls it down, causing an elevator to slide up from the ground, with a boy sitting on it. The PBS Kids Go! logo is seen embedded on the door, with the "GO!" text popping out to the music.
 * Not All Blocks: A boy and a girl run in front of a large door. The boy then steps on a button on the ground, causing the door to turn. As the boy runs inside, he peeks outside, as the girl is looking at him. The PBS Kids Go! logo is seen on the door.
 * Peephole: A boy waves out of a peephole. As a girl runs towards him, she also looks through it. On the other side, a boy is also waving to the kids. The camera then moves to the other side to reveal the peephole is part of the PBS Kids Go! logo. "GO!" then pops out of it.
 * Rock Climber: A boy pushes a speech bubble button, revealing multiple climbing walls, with a climber already on it. The PBS Kids Go! logo then forms on the left side of the screen. Two girls then run on a nearby platform.
 * Rubiks Cube: A boy notices a slanted button. He then rotates it into place and presses it, causing multiple blocks to move and form the PBS Kids Go! logo in a mosaic pattern. Another boy, atop an  cube, waves at the boy on the ground.
 * Wall: A boy slips, but is stopped by a cube behind him. He turns around and pushes it toward the other side, revealing that the PBS Kids Go! logo is printed on the cube. Two girls stand on the opposite end of the wall, as the cube jumps.

Technique: Live-action combined with CGI. Designed by Primal Screen.

Music/Sounds: Same as the 1st and 2nd logos.

Music/Sounds Variants: The "Binoculars", "Rubik's Cube", "Block Dam" and "Lever" logos all have alternate audio tracks on the Primal Screen website, two of which are essentially just the PBS Kids Go! bumper music without any sound effects.

Availability: Very rare. All shows that used this logo either no longer air or have been plastered with PBS Kids logos. However, certain episodes of Arthur and WordGirl use promos that include variants of this logo. The PBS station WSBE is known to use old prints of SciGirls in the past that still include this logo, but it is unclear if they still do. Though SciGirls still airs on the station, no videos showing program breaks after SciGirls on WSBE have been uploaded after 2020. PBS still has broadcasting rights to ''Fetch! with Ruff Ruffman'', which wasn't edited to exclude the logo outside of the PBS Kids 24/7 channel, so it is possible that some stations could air it again and the logo would be seen, though no stations currently air it.
