Network programmers are betting that sitcoms are poised for a comeback. Of 71 scripted pilots hoping to get regular slots on network schedules next season, 33 are comedies, the Los Angeles Times reported today (Tuesday). The newspaper noted that the current recession figures in the planning, since sitcoms are generally less costly to produce than dramas, particularly those shot before a live audience with multiple cameras. Of the 33 sitcom pilots being produced, 19 of them use a multi-cam format, allowing them to be produced in less time than those shot with a single camera. As of now, only CBS airs multi-cam sitcoms, but Angela Bromstad, president of primetime entertainment at NBC, told the Times. "When you look at what's working and what is standing in a very crowded environment, the multi-cameras on CBS are doing very well and prove that it's not a dying format."
