By 1985, computer graphics technology had progressed sufficiently that on 18 February the mechanical mirror globe was retired in favour of the new "Computer Originated World", or 'COW', which showed a semi-transparent blue globe with golden continents and gold "BBC1". It was created by the BBC graphics and computer departments with work starting on it in 1983. The globe was originally planned to launch on 1 January 1985 but was delayed until 18 February that year by the then controller of BBC One, Michael Grade, in order to make part of a new look for the channel as ratings began to slide. From start-up until 6:00pm that evening, the older 'NODD' mirror globe was used. From 7:00pm until closedown that night, the newer 'COW' globe was used. The first ever programme to be introduced by this new globe was Wogan, a chat show presented by Terry Wogan.
