Channel Surfing: Conan O'Brien Turns Down NBC Proposal, "Lost" Returnees, J.J. Abrams Taps Former "Doctor Who" Co-Star, "Glee," and More

Welcome to your Wednesday morning television briefing.

Yet another twist in the NBC latenight drama: Conan O'Brien has rejected NBC's proposal that he shift The Tonight Show to 12:05 am in order to accommodate a half-hour Jay Leno format at 11:35 pm. The move, announced via a slightly tongue-in-cheek statement, did not indicate that he had quit and The New York Times' Bill Carter cited an unnamed source that the network that indicated that O'Brien would depart after a financial settlement had been reached. "After only seven months,” said O’Brien in a statement, “with my Tonight Show in its infancy, NBC has decided to react to their terrible difficulties in prime time by making a change in their long-established late-night schedule."
