One of the greatest contestants in the show's history will temporarily take up the mantle.

The next Jeopardy host is here: Ken Jennings, one of the greatest contestants in the show's history.

The favorite to take the podium, Jennings is the popular contestant-turned-consulting producer, crowned champion in the Jeopardy Greatest of All Time tournament earlier this year.

The last episodes that Trebek filmed will air in early January 2021, and the episodes hosted by Jennings and other interim hosts will air starting Jan.
