Playboy Club's cancellation came after the drama premiered Sept. 20 to underwhelming ratings, attracting 5 million viewers and a 1.6 rating in the advertiser-coveted adults 18-49 demographic. The most recent episode -- the show's third -- pulled only 3.2 million viewers and a 1.2 rating.

The Parents Television Council applauded the news, saying it was "pleased" and "grateful" that the show had been canceled.
