'''Final Note:''' This logo was retired because of the fact it was the only live mechanical model used by BBC1 by 1984, and the regular maintenance and calibration required was making it tiring and a hassle to use; even this logo could not help much in soothing common difficulties such as bad positioning, odd colours, etc. The globe was also becoming old-fashioned, due to its long service since the invention of colour, as well as the CGI revolution, which ironically began with sister channel BBC2, with their stripped "2" ident. The NODD system was abandoned with the globe, as all idents and clocks were now electronically generated. Programme slides remained the exception; they were still optically developed until the late 1980s when the programme slides became electronically generated with the quantel paintbox. The logo's last appearance was 5:35pm on Monday 18 February, introducing a new series of Grange Hill. London viewers would see it one more time, before ''London Plus'' at 6:35pm.
