Do Not Adjust Your Set is a television series produced originally by Rediffusion, London, then by the fledgling Thames Television for British commercial television channel ITV from 26 December 1967 to 14 May 1969. The show took its name from the message which was displayed when there was a problem with transmission. It included early appearances of many actors and comedians who later became famous, such as Denise Coffey and David Jason. Eric Idle, Terry Jones and Michael Palin later became members of the hugely successful Monty Python comedy troupe. Although originally conceived as a children's programme, it quickly acquired a cult crossover following amongst many adults, including future Pythons John Cleese and Graham Chapman.
