Primetime Ratings: ABC Wins with Grey's Uptick

CSI Propels CBS to Second

Grey's Anatomy led ABC to victory in the primetime network race Thursday night, according to Nielsen Media research overnight numbers.

Grey's averaged a 7.7 rating/18 share in the demo, up from a 7.4/18 the week before and enough to nudge ABC into first.

ABC averaged a 5/13 on the night, up from a 4.8/13 the week before when it was edged out by CBS for overnight honors. ABC won the 10 p.m.-11 p.m. hour with Big Shots, which averaged a 3.9/11, but that appeared to be due largely to its Grey's lead-in. The show's ratings dropped from a 4.6/12 in its first half-hour to a 3.2/9 in its second. Still, that 3.9 was an improvement from the 3.7 rating the week before.

CBS was second on the night with a 4.7/12 in the demo thanks to CSI, which was second to Grey's from 9 p.m.-10 p.m. with a 6/14, although that was down from its 6.3/16 a week ago.

NBC was third with a 3.7/10, led by The Office, which averaged a 4.7/11 from 9 p.m.-10 p.m. against Grey's and CSI.

Fox averaged a 2.1/5, led by Are You Smarter than a Fifth Grader at a 2.3/7 from 8 p.m.-9 p.m.

The CW averaged a 1.5/4, even with the week before.
