Friday's Dateline NBC is history. The newsmag is moving to Saturdays at 8pm in March, B&C says. A tipster calls the move "classic Jeff Zucker:" "He comes to a Dateline staff meeting THREE months ago and declares his 'full support' to Dateline and says he 'wouldn't be surprised if it went to 3 nights a week' -- and now has sent the show to the graveyard. Our leader is the most insincere guy at the network."
