TV Show Ratings for Thursday, 03/31/11 [finals]

The incredible success of American Idol helped to successfully launch FOX’s new reality series, Mobbed. On CBS, many of the shows had originals for the first time in weeks and the numbers were fairly status quo.

On NBC, all of the schedule was in repeats except for Perfect Couples and that sure-to-be-cancelled series dropped 37% when compared to last week’s episode. Grey’s Anatomy was way up because of the musical episode but Wipeout and Private Practice didn’t benefit.
