Ken Jennings During his first run of "Jeopardy!" appearances, Jennings earned the record for the highest American game show winnings. His total was surpassed by Brad Rutter, who defeated Jennings in the finals of the "Jeopardy!" Ultimate Tournament of Champions (first aired on May 25, 2005), adding $2,000,000 to Rutter's existing "Jeopardy!" winnings.
