100% is a television game show that ran in the United Kingdom from 31 March 1997 to 24 December 2001.
The Reg Grundy production was often billed as "The game show without a host" but it did, however, have a presenter in its announcer, former Thames Television newsreader Robin Houston. He read the questions off-screen throughout the show and was never seen by the viewers.
In its original format, three players would take three seconds or less to push buttons on the set corresponding to the multiple-choice answers of 100 general-knowledge questions.
Although pulling in reasonable ratings for the channel, it was dropped as part of a station revamp just before 2002.
