The Big Bang Theory will move from its 8:00 slot to follow television's most popular sitcom, Two and a Half Men, at 9:30, this fall. CBS, announcing its fall line-up at the Upfronts in New York, spelled out their new Monday night line-up.
How I Met Your Mother will kick off the night at 8, Accidentally on Purpose - a new sitcom with Jenna Elfman airs at 8:30, Two and a Half Men stays at 9, and The Big Bang Theory moves to 9:30.
The Big Bang Theory will now finish off CBS' Monday night comedy block, airing after Two and a Half Men - TV's most popular comedy. Two and a Half Men was co-created by Big Bang Theory co-creator Chuck Lorre, who now dominates the 9 o'clock hour.
The Big Bang Theory aired at 9:30 once this season, and got big ratings in the slot. CBS showed confidence in the show when it renewed it for two seasons, back in March. Two and a Half Men was renewed for 3 seasons. Rules of Engagement, which occupied the 9:30 slot this season, has been renewed, but isn't on CBS' fall schedule.
