FOX won with American Idol (6.4) and a repeat of Bones (2.4).
ABC was second with Wipeout (2.3), Grey’s Anatomy (3.7), and Private Practice (2.6). Private Practice really benefiting from Grey's Anatomy lead in.
CBS was third with NCAA Basketball (somewhere between 2.5 and 3.0 for a huge timespan).
NBC was last with Community (1.8), Perfect Couples (1.6), The Office (3.4), Parks and Recreation (2.4), 30 Rock (1.9), and Outsourced (1.5). Perfect Couples and Outsourced remain the odd men out.
