'CSI' gets 'Anatomy' lesson Thursday


NEW YORK -- "Grey's Anatomy" kept up its torrid pace durings sweeps, handily beating "CSI" head-to-head and giving ABC the win Thursday in the adults 18-49 demographic.

Meanwhile, "Survivor: Fiji" was up slightly in the demo compared to last week's premiere, once again beating ABC's "Ugly Betty" and "ER" won at 10 p.m. with its second-lowest rated original episode in its history.

"Grey's Anatomy" averaged 25.6 million viewers and a 10.7 rating/25 share in the adults 18-49 demographic, according to preliminary estimates released Friday by Nielsen Media Research. That continues its strong streak recently atop last week's 25.2 million viewers and 10.9/25 that was the highest demo ratings since the September premiere.

"CSI" (22.5 million, 7.2/17) was about average this season but down 26% from last February's 9.4/23 when it didn't have to face "Grey's Anatomy." NBC's "Scrubs" (6.2 million, 3.0/7) and "30 Rock" (5 million, 2.4/6) were both down from their season averages.

"Survivor" (16.3 million, 5.6/15) won the 8 p.m. hour about even with last week's performance (16.4 million, 5.7/15). It was ahead of "Ugly Betty" (13.6 million, 4.5/12), which was the highest demo rating since its September premiere.

The 10 p.m. hour was won by "ER" (11.5 million, 4.8/13) in the demo and CBS' "Shark" (15.1 million, 4.3/12). ABC's "Men in Trees" averaged 11.2 million and a 4.1/11 in the demo although it's likely to be revised downward due to "Grey's" going into it.

Nightly averages: ABC (16.8 million, 6.4/18); CBS (18 million, 5.7/14); NBC (8.7 million, 3.9/10); Fox (4.3 million, 1.9/5); and The CW (4.1 million, 1.7/4).
