Mayim Bialik Steps Down as 'Jeopardy!' Host for Remainder of Season.

Mayim Bialik, the current host of "Jeopardy!," has stepped aside with one week of filming left in the current season in support of the Hollywood writers strike. Ken Jennings, who hosted earlier in the season, will fill in for the final run of production. "Jeopardy!" writers, members of the Writers Guild of America, have been on strike since May 2. The strike has already had a wide impact on TV production, including late night talk shows, "Saturday Night Live," and several notable films and shows.
