And the Answer is: Why Is It Better to Be a Generalist Ken Jennings is known for his trivia prowess after setting (and continuing to hold) the record for the longest winning streak on Jeopardy! In 2004, he successfully auditioned for a spot on the show and went on an unprecedented 74-game victory streak worth $2.52 million. He then went on to appear in several special tournaments, including the ABC special, “The Greatest of All Time,” which he won. Later that year, he joined the game show as a consulting producer, and in early 2021, he guest-hosted the program for six weeks after the passing of long-time host Alex Trebek. In July 2022, Ken Jennings was announced as a permanent host sharing duties with Mayim Balik.
