After Dark was a British late-night live discussion programme broadcast on Channel 4 television between 1987 and 1997, and on the BBC in 2003. Roly Keating of the BBC described it as "one of the great television talk formats of all time" and the Daily Mail as "the most intelligent, thought-provoking and interesting programme ever to have been on television". In 2010 the television trade magazine Broadcast wrote "After Dark defined the first 10 years of Channel 4, just as Big Brother did for the second".
