100% is a television game show that was shown in the United Kingdom every weekday at 5.30pm from 31 March 1997, the day after the inception of its host television station Channel 5, until 24 December 2001, running for over 1,000 editions. Each show ran for 30 minutes with one commercial break. A Reg Grundy production, it was often billed as "The game show without a host" although it had a presenter, Robin Houston, who also presented One To Win, another daily quiz show on the same channel. He read the questions off-screen throughout the show and was never seen by the viewers nor, indeed, by the contestants. To keep production costs down, the shows were pre-recorded "as live" and in batches, normally over a weekend. The maximum number of shows that were recorded in one day was twelve, although the normal recording day saw ten shows being produced. There was a weekday afternoon spinoff series called 100% Gold which featured older contestants and was presented by Melinda Walker, plus a late-night series called 100% Sex which had questions of a more adult nature. All editions were recorded at Pearson Television's studios in Stephen Street, London. 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. During its run, a number of one-off specials were produced, usually to tie-in with a themed day or evening by the broadcaster, Channel 5. Although pulling in reasonable ratings for the channel, it was dropped as part of a station revamp just before 2002. Scores The original twist to the show was that, throughout the whole game, the players were told the individual scores (as a percentage of the number of questions answered correctly to that point), but not the player to whom those scores belonged. The scores were given to the contestants after 10, 30, 50, 60, 80, and all 100 questions had been asked, as a percentage of the number of questions they had correctly answered. They were also told whether there had been a change in the lead. Later on, the rules were changed so that the players now knew who had which scores for the first 50 questions. In all cases, the audience could see who had what score and during the last ten questions the scores were displayed on screen after each
