The globe ident was modified in January 1972 to include a new BBC logo with rounded corners and an italic serif font for the 'Colour' legend. On 28 December 1974 the ident was reworked further, with yellow continents over a dark blue background and the term 'COLOUR' removed. The legend "BBC1" was rendered in white, using a heavy weight of the Futura typeface. On 5 September 1981, the display was altered to green continents over a dark blue background with a double striped BBC1 legend in white.
