In 1964 the BBC began broadcasting both BBC1 and BBC2 with a unified design which came to be known as the 'Watchstrap' for obvious reasons, as both the animated globe and the animated clock were set on a band of grey and white horizontal stripes on a black background with the new slanted BBC1 or BBC2 logo centred in white beneath. NODD (Nexus Orthicon Display Device), universally known as NODDY by the BBC, was the mechanical means by which Channel Idents and clocks were displayed on-air, with the device rotating the globe and a dedicated monochrome camera filming the result in real time. NODDY was activated on cue from the Presentation Studio gallery by the Continuity Announcer.
