Aug. 23 (UPI) -- Actress Mayim Bialik will be the first guest host of Jeopardy! after executive producer Mike Richards stepped down as the game show's permanent host, Sony Pictures Television confirmed Monday.
Bialik, who had already been chosen to host Jeopardy! prime time specials and spin-offs, will fill in as host for the first 15 episodes of the daily show when it resumes production this week, Sony officials told CBS News and CNN Business.
