The bong game is a phone-in game show created in the 1980s by the London-based radio station, Capital Radio. It is a game based purely on chance, but remained suspenseful because both rewards and risk increased as it progressed. The game was invented by David Briggs, a former traffic reporter for Capital FM who went on to create Who Wants to Be a Millionaire? He also provided the smooth voice on the recordings. The contestants were primed by Capital Radio's Breakfast Show host, Chris Tarrant, whose collaboration with Briggs led to him becoming the presenter of Who Wants to Be a Millionaire?
