Ratings were down across the board, so don't be surprised if the shows had abnormally low ratings. We'll see if they rebound next week.
CBS won with Survivor: Heroes vs. Villains (3.5), The Mentalist (2.8), and CSI (2.8). Considering how low all the ratings were, it's hard to tell if the time switch between The Mentalist and CSI mattered.
ABC was second with FlashForward (1.4), Grey’s Anatomy (3.5), and Private Practice (2.7). I don't see a future for FlashForward.
Fox was third with Bones (2.4) and Fringe (2.2).
NBC was last with repeats of The Office (1.6, 1.8) and a new episode of The Marriage Ref (2.2).
