Long-form answers:
knowledge: content: Who Wants to Be a Millionaire? (abbreviated WWTBAM and informally known as simply Millionaire) is an international television game show franchise of British origin, created by David Briggs, Mike Whitehill and Steven Knight. In its format, currently owned and licensed by Sony Pictures Television, contestants tackle a series of multiple-choice questions to win large cash prizes in a format that twists on many game show genre conventions – only one contestant plays at a time, similar to radio quizzes; contestants are given the question before attempting an answer, and have no time limit to answer questions; and the amount offered increases as they tackle questions that become increasingly difficult.

content: Out of all contestants who have played the game, relatively few have been able to win the top prize on any international version of the show. The first was John Carpenter, who won the top prize on the American version on 19 November 1999. Carpenter did not use a lifeline until the final question, using his Phone-a-Friend not for help but to call his father to tell him he was about to win the million.
