The $64,000 Question (British game show)

Each contestant answered questions based on their subject of expertise. The first question earned 100 sixpences (£2 and 10 shillings), correctly answering the next question added £10 to the player's winnings. Each of the next two questions featured two parts and answering both parts doubled the player's winnings to 1,000 sixpences (£25) and 2,000 sixpences (£50) respectively. The remaining questions featured three parts, then four parts, five parts, six parts, and the final question required at least seven parts to be answered correctly in order to win the top prize. In late 1956, the values doubled so that the values started at £5 (100 shillings) and increased to £3,200 (64,000 shillings). £3,200 was actually substantially higher, in real terms (i.e. accounting for inflation), than anything on offer on British TV for most of the 1960s, 1970s and 1980s, after the Independent Television Authority (later the Independent Broadcasting Authority) imposed prize limits on game shows after the general discrediting of the genre following the quiz show scandals in the US and rumors that the British version of Twenty One was also corrupt.

The values started at £1, followed by questions valued at £25 and doubled with each subsequent question with £400 and £1,600 each being guaranteed. The £200 and £400 questions each featured two parts. The £800 question required three correct answers and the next question required four correct answers in order to secure £1,600. The contestant must then answer a follow-up question in order to attempt the five-part £3,200 question in a soundproof booth known as the "Isolator". The £6,400 question required six parts to answer correctly. On the £3,200 and £6,400 questions, missing one part required the contestant to answer a "reserve part" correctly. £6,400 was a significant amount of money for a British game show at that time, though still probably worth less than the original had, which was £3,200. The 1991 series replaced the £1-£50 questions with the Basic 64 which started at one pound and doubled up to 64 guaranteed pounds before the £100 question. In 1993, prize limits were lifted by the Independent Television Commission, paving the way for the eventual arrival of Who Wants to be a Millionaire? in which the eleventh question was worth £64,000 until the format of the show changed in August 2007. With the 2018 revival the £64,000 level was reintroduced.
