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. Jennings regained the record after appearing on several other game shows, culminating in an appearance on "Are You Smarter Than a 5th Grader?" (first aired on October 10, 2008), though Rutter retained the record for highest "Jeopardy!" winnings and once again passed Jennings' total after his victory in the 2014 "Jeopardy" Battle of the Decades tournament.
