CBS won with Survivor (4.1), CSI (3.0), and The Mentalist (3.2). The Mentalist did better than CSI again. CBS better have a plan for next year.
ABC was second with Flashforward (1.6), Grey's Anatomy (3.8), and Private Practice (2.9).
NBC was third with Community (1.9), Parks and Recreation (1.9), The Office (3.6), 30 Rock (3.7), and The Marriage Ref (1.9).
Fox was last with Bones (2.6) and Fringe (2.0). Fringe isn't looking good, but it's already been renewed. Big questions for next season though.
