Jeopardy! host Ken Jennings says Mayim Bialik exit caught him ‘off guard’

Jennings says he was not expecting co-host to leave but is eager to equal Alex Trebek's record of 38 years as sole host

Ken Jennings says he was as surprised as anyone to learn he would become the solo host of Jeopardy!, the long-running US gameshow.

In an interview published on Monday by the Hollywood Reporter, Jennings, the most famous contestant in the quizshow's history, said he was not expecting co-host Mayim Bialik's announcement that she was leaving.
