The show announced Wednesday that Katie Couric, the journalist and former Today host, will become the first woman ever to host the show. Others on tap are Mayim Bialik, Aaron Rodgers and journalist Bill Whitaker.
The show is currently using a series of interim hosts to replace Alex Trebek, who died of cancer on Nov. 8. That process began when record-holding contestant Ken Jennings made his debut on an episode that aired Monday.
