The CEO of HBO Richard Plepler has admitted he regrets rejecting Mad Men, according to Business Insider.

During a panel at the Paley Center's International Council Summit in New York City Thursday, Plepler was asked what one show makes him go "Oh man, I wish we had that one."

"I'm an unabashed fan of 'Mad Men,'" said Plepler. "You know I love the show. I think Matt [Weiner] is a gifted writer and producer. I was a big fan of the show all through its incarnation.”
