3-2-1 was a popular (and very successful) British game show that was made by Yorkshire Television for ITV. It ran for ten years, between 29 July 1978 and 24 December 1988, with former Butlins Redcoat Ted Rogers as the host.
It was based on a Spanish gameshow called Un, dos, tres... responda otra vez and was a trio of three shows in one, a quiz, a variety and game shows.
The show was a huge success consistently pulling in large ratings. The first series, though, intended as a summer filler, attracted up to 16.5 million viewers and subsequent years never failed to peak below 12 million. The show occupied a Saturday early evening slot for most of its run.
The final Christmas special (broadcast on 24 December 1988) attracted 12.5 million viewers.
