TV Show Ratings for Thursday, 04/21/11 [finals]

As per usual, American Idol was the big winner of the night but it was down a bit. The episode of Bones was a backdoor pilot for a spin-off. The episode was down but that probably won’t impact FOX’s decision very much.

On NBC, despite the fact that Will Ferrell guested on The Office once again, it was down. Community took a big hit and The Paul Reiser Show sank even lower than its premiere. Will episode three air before that one’s cancelled? Looks doubtful.

Over on The CW, Vampire Diaries and Nikita didn’t vary much from last week’s episodes. Both ABC and CBS were in repeats.
