Fox has cancelled new drama Alcatraz, which premiered earlier this year in January as a mid-season replacement. The series got off to a solid start in the ratings, but viewership dropped off significantly over the course of its 13 episodes. The show's last four episodes rated a series low 1.6 in the key adults 18-49 demographic, which was clearly not enough for Fox to bring back the series.
