Sale of the Century was a UK game show based on a US game show of the same name. It was first shown on ITV from 1971 to 1983, hosted by Nicholas Parsons. The first series was supposed to air only in the Anglia region, but it rolled out to other regions since 8 January 1972 and achieved full national coverage by the end of 10 May 1975, at which point it was one of the most popular shows on the network - spawning the often-mocked catchphrase "and now, from Norwich, it's the quiz of the week." It has been revived twice first on Sky One from 1989 to 1990 hosted by Peter Marshall and then on Challenge TV in 1997 hosted by Keith Chegwin.
