Fifteen to One is a British general knowledge quiz show broadcast on Channel 4. It originally ran from 11 January 1988 to 19 December 2003 and had a reputation for being one of the toughest quizzes on TV. Throughout the show's original run, it was presented and produced by William G. Stewart. Thousands of contestants appeared on the programme, which had very little of the chatting between host and contestants that is often a feature of other television quiz shows.
