TVWeek reports that beginning Friday, Dec. 5, Dateline is returning to the NBC lineup. The show will air at 10pmET. The network moves back "Lipstick Jungle" to 9pmET to make room for Dateline, while moving the drama "Crusoe" to Saturdays at 8pmET. (A desert island drama on a Saturday night? Hey, it worked for ABC in the late '70s and early '80s with "Fantasy Island"... but not so much for the 1998 remake).
