In the aftermath of Maura Tierney's departure, the premiere date that was originally set for September 23, 2009, was moved to March 1, 2010, at 9:00 p.m., but it was again delayed to the following day at 10:00 p.m. in the aftermath of "The Jay Leno Show" cancellation and 2010 Tonight Show conflict, requiring the return of scripted programming to the later time slot. The series premiered on March 2, 2010, at 10:00 p.m., on NBC, following "The Biggest Loser". The series premiere was dedicated to the memory of Nora O'Brien, a vice president at NBC, who died on the set of "Parenthood" on April 29, 2009, after collapsing from an aneurysm.
