Double Your Money is a British quiz show hosted by Hughie Green. Originally broadcast on Radio Luxembourg, it transferred to ITV in 1955, a few days after the commercial channel began broadcasting. It was produced by Associated-Rediffusion until 1964 and then by Rediffusion London, and it finished in 1968 when the company lost its franchise. There were 260 thirty-minute episodes. Throughout its run the show was one of the most consistently popular programmes on British television. The quiz format was similar to The 64,000 Dollar Question, with prize money approximately doubling at each question up to £1000, and multi-part answers being required at the harder stages. When contestants hit the £1,000 Treasure Trail, they were placed in sound-proofed 'isolation booths', where the fans were turned off and the temperature grew, making contestants sweat and look nervous. The 8 November 1966 show came from The House of Friendship, Moscow, Russia, where Monica Rose and Natasha Vasylyeva were both hostesses and, because the Communist Party would not allow money to be given away, the big prize was a television set. The Polish version of this quiz was "Wielka Gra".
