Hugh Hefner and Amber Heard Hugh Hefner and Amber Heard

Now that the dust is starting to settle, Playboy founder and CEO Hugh Hefner says he knows why The Playboy Club was canceled.

"I'm sorry NBC's The Playboy Club didn't find its audience," Hefner tweeted late Tuesday, hours after NBC announced that  the remaining episodes of the show would be pulled. "It should have been on cable, aimed at a more adult audience."

NBC orders Up All Night and Whitney, cancels Playboy Club

The Playboy Club became the first freshman series of the 2011-2012 TV season to get the axe after the '60s-set drama averaged about 3 million viewers for its first three episodes. In addition to low ratings, the series was met with resistance from the Parents Television Council, which urged advertisers to boycott The Playboy Club and called for NBC to cancel the "degrading and sexualizing program immediately." In June, NBC's Salt Lake City affiliate announced it would not air the show. My Network TV picked it up weeks later.

However, Hefner also noted that there is "renewed interest" in making a film based on his life and the start of the sexual revolution.

Are you sad The Playboy Club is gone? Do you think it would have worked on cable?
