Fall 2009's least-watched shows: Zap2it's Year in Review

Viewers: 5.211 million Fall 2009 ranking: 81st Fun fact: For ratings purposes, NBC chops up its Sunday-night NFL pre-game show into three parts. Part 1 is not counted by Nielsen (it's considered "sustaining" -- i.e., no ads), and part 3, much closer to kickoff, averages better than 10 million viewers.
