Advertising Age reports that while NBC is moving forward on a fourth season of “Heroes,” you can expect fewer episodes.
NBC is expected to trim the number of episodes of its sci-fi drama it airs next season, according to people familiar with the situation, and also run those episodes closer together to avoid interruptions to the story line week by week. The network is considering running 18 to 20 episodes of the series in the [2009-2010] season, those people said, down from 25 this season.
