Ken Jennings

Jennings brings a former contestant's understanding to Jeopardy!, having made his name with a 74-game winning streak in 2004. That background is useful when a game turns on a wager, a difficult category or a split-second decision. His quick delivery and dry humour suit viewers who enjoy the contest as well as the trivia. Watch how he keeps a familiar structure moving while leaving space for the players' different personalities.
