The most famous idents of the Noddy system were the BBC1 mirrored globes used between 1969 and 1985, albeit with minor colour changes. The system machinery consisted of an internally lit, rotating globe in front of a concave mirror. The oceans were painted onto the globe in metallic black paint, leaving the land masses as unpainted patches. The original globe ident introduced on 15 November 1969 featured blue continents and legend against a black background. The legend included the word 'COLOUR' after the BBC1 corporate logo, to identify the new programme format and act as an advertisement to the vast majority of viewers, still watching in black and white: the colour version of the television licence which financed the BBC was much more expensive. Full colour broadcasts across the UK did not become available until 1976. The colours of blue and black were chosen because they were still easily distinguishable to those with black and white televisions. Another version of the globe without the 'Colour' legend was used before black-and-white programmes, of which there were still many in the BBC1 schedule in the early 70s.
