At 7am on the 16th February 1991 a new look BBC1 was unveiled. Unlike the previous globe this one was designed by Martin Lambie-Nairn and introduced corporate branding to BBC1 for the first time. The design featured a swirling world of shadows and reflections. Another first was the fact the ident was played of a laserdisk. The actually ident never appeared until 9am.
Here's the first day of the new look BBC1 from 16th February 1991.
