The NYT says that the show has advertisers feeling queasy:

The network has filmed only one sting operation so far this year, compared with seven in 2006. In several ways, the high ratings for “Predator” have come at a high price for NBC. Some advertisers say they are wary of being associated with the show’s content, in which men lured to a house by the promise of a sexual encounter are instead surprised by Mr. Hansen and then arrested.

Critics have also raised ethics questions about the series because NBC coordinates the investigations with a private watchdog group and local police departments. And two lawsuits are pending against the network, one by a former producer and another by the sister of a man who committed suicide as police officers approached his house, accompanied by NBC camera crews.

Some media buyers were hesitant about buying ads on the series even before the recent spate of bad press reports. Andy Donchin, director for national broadcast for the advertising agency Carat USA, said advertisers could be wary of the show’s unsavory theme. “We’re all concerned with what content we’re associating ourselves with,” he said.
