CBBC

Background
CBBC (called Children's BBC from 1985-1997) is a division of the British Broadcasting Corporation and is aimed at children ages 6 to 12. It originally started on September 9, 1985.

1st Logo (September 9, 1985-1989)
Nicknames: "B", "Micro B", "Children's BBC"

Logo: On a black background, the letters "BBC" (in red, green and blue respectively) appear one by one, then "CHILDREN'S" pops up in light yellow.

Trivia: This logo was made on the BBC Micro B computer.

Variants:
 * Originally, "CHILDREN'S" was underneath the BBC text and had no animation except the flickering. In its early days, the logo took place on a blue background. In 1986, a later version was created, in which "BBC" is in gold and "CHILDREN'S" is in teal, and the background is either black (for BBC One) or white (for BBC Two). Sometimes, the colors of the B's would be swapped.
 * The later version can also be seen on BBC1 Saturday Superstore's "Presentation Tour" when Philip Schofield pushes the many buttons on his vision mixer. Only the end flickering is shown during its cameo. A still version of it on a black background can also be seen on one of his fourteen front monitors.

FX/SFX: A wipe transition is used. Also, the first variant uses the same mistake as the 2nd Delta Video, Scholastic-Lorimar Home Video, the 5th South Carolina ETV, the DHX Media logo, the 1995 Cartoon Network Productions, and the MCA Videocassette, Inc. logos.

Music/Sounds: A high-pitched 4-note 8-bit theme.

Availability: Extinct on TV. It is preserved on recording media by many, however.

Editor's Note: The computer graphics are cheesy and the music may bother a few.

2nd Logo (1987-September 4, 1989)
Nicknames: "Animated Forms", "Children's BBC II"

Logo: On a black background, moving trails begin to form shapes via their initials, showing the letters of the word "CHILDREN'S". Then, the trails form the BBC logo.

Variant: A shorter version also exists.

FX/SFX: The moving trails forming the logo.

Music/Sounds: A funk-styled theme song.

Availability: Same as before.

3rd Logo (September 4, 1989-September 8, 1991)
Nicknames: "Archimedes", "Children's BBC III"

Logo: On a teal CGI background with copies of the CBBC logo engraved in, a gold BBC fades in like a TV aerial, then "CHILDREN'S" wipes in turquoise.

Trivia: This logo was made on the Acorn Archimedes computer.

FX/SFX: CGI animation.

Music: An electronic jingle, accompanied by a chorus and a 3 note fanfare once the BBC text is formed.

Availability: Same as before.

4th Logo (September 9, 1991-September 25, 1994, 2015)
Nicknames: "Fridge Magnet", "Children's BBC IV"

Logo: On a black background, letters in an odd font which spell "CH|LD)REN'S" form out and then rotate to their usual positions. The 1988 BBC logo pops up afterwards.

FX/SFX: The letters forming, the rotation, and the BBC logo appearing suddenly without transition.

Variants:
 * On the later variant, the 1988 BBC logo takes slightly longer to pop up.
 * An in-credit version of the logo also exists.
 * A variant exists where an explosion occurs. Later, a shape-formed face appears distorting in a black background, sometimes cutting to split-second shots of the logo. After the logo is formed, the 1988 BBC logo appears under the "N" in "Children's", as the text "...But First This" wipes in below the logo.

Music/Sounds:


 * September 9, 1991 – April 1992: A downbeat electronic theme. This theme was considered to be too dull and was eventually replaced with the next theme.
 * April 1992 – September 26, 1994: A bouncy, upbeat theme with a huge thud at the end. This was usually followed by a man saying "OOH! OOH! OOH!", taken from the song "Looking Out My Window" by Tom Jones.

Music/Sounds Variants:
 * On Christmas occasions, a rendition of "Jingle Bells" is heard.
 * Another variant exists where a man can be heard saying "Tell that aardvark, it's a wrap." This is most likely a reference to Children's BBC puppet presenter Otis the Aardvark.

Availability: Same as before.
 * The ident made a surprise appearance, on the 30 Years of CBBC TV special made to commemorate the network's 30th anniversary, since its launch in 1985.

5th Logo (September 26, 1994-October 3, 1997)
Nicknames: "Fridge Magnet II", "Children's BBC V"

Logo: On a gradient background, the same "Children's" sign from the last logo rendered in 3-D forms itself in chunks. A white 3-D 1988 BBC logo later appears.

Variants:


 * Alien – A farmer's field is shown, with an alien spaceship hovering above and a scarecrow standing in the fields. The scarecrow turns around to reveal an alien in its place, and the shot pans out to the field with "Children's" inscribed in it, and the BBC logo on the spaceship.
 * Bee – A bumble bee encounters a Venus flytrap, which it then swallows, before turning into the black and yellow BBC logo and the "Children's" letters falling from above.
 * Boy – Letters from the "Children's" jump out from his face in various orders, and when the boy opens his mouth, the 'Children's' can be seen on his uvula, dangling from the roof of his mouth, with the BBC logo on his tongue.
 * Christmas Rooftop – On a winter's night (with the flashing grey "Children's" logo in the dark), Father Christmas twists a few times in a chimney (with the "Children's" logo on the sack next to the chimney) and boings up high into the sky. The reindeer stands in the chimney for a few seconds. Then, Father Christmas crashes back into the chimney and the BBC logo appears on the grey paving slabs on the roof after the snow slides off the roof, while the reindeer have a couple giggles behind the rooftop.
 * Christmas Tumble – Father Christmas strolls along the snow and then boings out of sight when letters of the "Children's" logo (and a couple of presents) fly in all directions. Father Christmas then gasps when he sees the "Children's" logo electrocuting on the reindeer's antlers, while he holds the BBC logo between his teeth.
 * Cow – Four cows are seen standing on small balls of grass. The last one blows a bubble containing the "Children's" logo, with the BBC logo contained in three flowers.
 * Egyptian – In Egypt, a mummy walks past where a lizard sits on the coffin. A lid opens and the mummy's bandages come undone one by one. The letters of "Children's" are shown inside while the lizard does an Egyptian dance.
 * Frankenstein – A sad monster looks out of the window. Thunder rumbles and lightning crackles as the machine contains the "Children's" logo. The monster cheers himself up by pulling every lever of the machine whilst electrocuting himself.
 * Jazz – The Children's BBC logo is split vertically and stretched in many directions against a plain blue background, accompanied by a jazzy version of the theme.
 * Mechanical Dogs – Metal, mechanical dogs bark at letters of the "Children's" logo raised on metal stilts above them, which come together to form the logo. The BBC logo is on one of the dogs.
 * Otis the Aardvark Paint – A cartoon version of Children's BBC's puppet Otis paints a picture, with the logo in the middle of the painting.
 * Otis the Aardvark Toffee – Otis eats toffees out of a tin, and gets his nose caught in it. The logo is on the bottom of the tin.
 * Pig – A live piglet roams around an area with numerous "Children's" logos imposed on the floor, and just as many BBC logos imposed on the back wall. Various shots of the pig end with the Children's BBC logo on the pig's rear.
 * Princess & Frog – A princess kisses a frog, turning her into a variety of objects including a cow and a pair of pants, before becoming a frog. Another kiss turns both into the Children's BBC logo, before the changes continue.
 * Sculptor – A man in a toga sculpts a block of stone, with the BBC logo carved into it. He eventually hits it too hard, resulting in the stone crumbling away to reveal "Children's". The man then crumbles into a delighted child.
 * Singing Friends – Two animal friends (bird and fish) sing a short jingle about Children's BBC, while the fish holds up the lyrics. The Children's BBC logo appears on the back wall.
 * Space – A spaceship flies around some planets, before crashing into a moon, leaving the Children's BBC logo to circle the wreckage.
 * Surfboard – A man surfs on a board before falling off, sending a large wave into shore, which washes up the Children's BBC logo.
 * Teen's Bedroom – A teenager straggles out of his messy bedroom into the hall. While he is gone, numerous letters of "Children's", the BBC logo, and the logo of the channel it is on all appear in different locations around the room. The same is repeated when he staggers back in.
 * Underwater – A diver appears inside a fish bowl, only to reveal the bowl being underwater, inhabited by an Elvis fish.
 * Beginning in January 1996, the background was changed to a vibrant yellow and a grey 2-D 1988 BBC logo appears.

Logos:

FX/SFX: 2D animation.
 * Blobs – Black blobs, similar to those found in a lava lamp, are seen rising up the screen.

 * Magician – A magician performs the act of pulling his own shirt off, as he attempts to pull something from his top hat, much to his embarrassment.

 * Mole – A mole digging a tunnel comes to the surface to clear his glasses, before continuing on.
 * Mouse – A mouse (out of breath) arrives on screen and comes up with the idea of becoming a bicycle by taking his ears off for wheels, his tail for handlebars, and his nose for a seat. The mouse then cycles quickly off-screen, with the rest of its body looking like a bike racer. A still from this ident was used when they had technical difficulties at the time.
 * Octopus – An octopus swims into view, spots the viewer, and hides itself in its own ink, allowing itself to get away.

 * Snail – A snail moves, checks if anybody is looking, and quickly scratches its back by lifting its shell off.
