1. Channel Four And BBC Ident History

1964 - The first ident was a  continuation of the BBC-tv ident of 1963. It featured the globe on a white background. The original ident had a BBC-tv logo. This was changed to just BBC when the channel was launched. 1966 - While the BBC 1 ident symbol remained, a "watch-strap" globe was introduced in 1964, showing the globe in the middle of a striped band. In 1968, the channel converted to colour - the globe and BBC 1 logo remained. 1969 - The first colour ident was introduced. A blue and black mechanical globe rotated while a curved mirror placed behind made up the famous image. 1972 - The globe and colour scheme remained the same, but a rounder, italic font was used for the ident introduced in 1972. 1978 - A new blue and yellow globe was introduced. The colour was added using electronics and a new big bold font was introduced. 1981 - A colour change was made to the globe - yellow became green. The caption also changed to a double line version (similar to the BBC 2 logo of the time). 1985 - The new rotating gold and blue BBC 1 globe was introduced. Called COW, for Computer Originated World, it was the first time that BBC 1 had abandoned mechanical models and still slides and used a completely computer generated image. 1991 - The COW globe was replaced with a new on-screen image designed by Lambie-Nairn (who worked on the Nine O’Clock News ident). The design was a swirling world of shadows and reflections. 1997 - The new style BBC ONE ident and logo was dominated by the red and yellow globe balloon. The balloon was filmed flying over 10 different British locations. 2002-2006 - these idents where publicly disapproved as they said that the idents were overtly politically correct as some idents used dancers in wheelchairs, these where rhythm and movement idents and where hugely unpopular.

2006-present day - After four years, the idents were replaced themselves by a new set introduced on 7 October 2006, abandoning the overtly red color scheme yet retaining the colour slightly less obviously as the main color. The relaunch brought about a new channel logo once more with the box replaced in favor of a lowercase name, effectively appearing as BBC One.

channel four

1982-1992 - the first channel four ident was screened in 1982,The award winning Channel Four identity was designed in 1982 by Robinson Lamb-Nairn. They won the initial pitch against Michael Peters and Wolf Olins. 
  
From their initial presentation Lambie-Nairn researched Channel Four's philosophy and seized the fact that they would be buying all their programs in, so Channel Four would be a patchwork. 
  
Their first idea was to illustrate the coming together of these elements. The first six ideas of 'coming together' all implied movement. One idea used the the colours of a television gun (RGB) and Channel Four liked the use of strong color and agreed the 'coming together' theme should be emphasised and developed further. they also make it so that it would link to a certain occasion for example in christmas they would add a christmas theme. they would also add themes such as sports themes which where added on 1984 and 1992 to celebrate different sports occasions such as the italian league they did a Italian football ident, they would also do idents to promote various programs such as, 'dinomania or atm comedy'.  

1999 - they used this ident in 1999 they had various different colors to this ident, it was very basic however it included the new logo in white which we see today in channel four, it includes colors such as red, teal, purple and yellow to add a change to it. 

2000-2013 - these are the most recent idents and the most modern they include the logo with a scene behind it for example in this photo there is a field of plants in this one, and in the most recent 2013 one there is the logo which is slowly made in different scene for example in this one it is a block of flats and bits of the flat combine to make the logo this makes the cannel more interesting and makes people want to watch it
