David Nevins has a history of working at NBC and Imagine Television (Arrested Development, Friday Night Lights, 24). So he knows something about Emmy-winning, critically loved shows that don't get huge ratings. But now, as president of Showtime, ratings don't matter, and the awards and critical love that Homeland -- the first show he put on the schedule -- is getting is making Nevins very happy. He tells the story of how Homeland was developed and that he believes television needs to defy savvy TV viewers' expectations.
