Long before ‘Branding’ agencies got their hands on television companies the original BBC, on-screen identity, fondly referred to as the ‘bat’s wings’ was designed by one Abram Games and introduced in 1953 when there was still only one television channel.
Here is Games with his elaborate mechanical contraption featuring a spinning globe in the centre, surrounded by two spinning 'eyes'. Apparently shortly after it was filmed it broke down, luckily it wasn't needed again. The identity stayed in daily use on air until 1963.
You can see an immaculate animated recreation of the identity in all its glory here.
