Jennings won 74 Jeopardy games before he was defeated by Nancy Zerg on his 75th appearance. The question was "Most of this firm's 70,000 seasonal white-collar employees work only four months a year." Jennings guessed "What is FedEx?" while Zerg responded correctly with "What is H&R Block."
Jennings' total earnings are just over $3 million.
In the spirit of the anniversary, 9NEWS decided to conduct their own trivia challenge.
Between Gary, Kyle Dyer and TaRhonda, who do you think won the 9NEWS Jeopardy game?
