CBBC
CBBC was originally launched as Children's BBC in September 1985 as a strand of programming for children aged 6–13. The first idents consisted of Children's on top of a large BBC is the a similar style to a rushed scribble, generated live on air by a BBC Micro computer. However, 2 years after launch, the idents were replaced by an animated sequence of the letters spelling out Children's with an outline of an object corresponding to that letter. This was replaced by a computer generated sequence in 1990.
In 1991, the BBC corporate revamp meant that Children's BBC was given a makeover. The result was a logo centred on a stylised Children's with a corporate BBC logo at the bottom of the screen. In 1994, the Children's BBC idents changed in style; many featured cartoons or computer generated graphics where the stylised Children's and the BBC corporate logo would feature somewhere.
Children's BBC was officially renamed CBBC in October 1997, with the production of appropriate idents. The idents all had a yellow background, and black subjects and often in the cartoon style. When CBBC was given its own channel on the digital terrestrial platform on 11 February 2002, the CBBC "blob" ident was created. These animated 'bugs' were designed by Lambie-Nairn, and were always green in colour. The blob was later refreshed and given a 3D appearance in 2005.
CBBC relaunched again in the autumn of 2007, with a new logo revolving around the letters of CBBC, each in a different style. A new set of idents followed these up, revolving around scenes including each of the 4 letters before coming together at the end. These scenes could involve cartoon figures, or stars of current CBBC programmes. In 2010 the logo was updated to look more 3D.
