ABC's "Grey's Anatomy" and CBS' "CSI" put up the best numbers once again on Thursday this week, but it was a night for less celebrated skeins like "Ugly Betty," "Smallville" and "Shark" to also shine. The Alphabet led in adults 18-49, and CBS in total viewers.
According to preliminary nationals from Nielsen, "Ugly Betty" (4.5 rating/12 share in adults 18-49, 14.1 million viewers overall) — coming off its Golden Globes victory on Monday — matched its second best demo delivery to date and drew its largest overall audience since Oct. 5. The hourlong comedy led its timeslot among young adults, overtaking NBC laffers "My Name Is Earl" (4.2/11 in 18-49, 9.7 million viewers overall) and "The Office" (4.5/11 in 18-49, 9.3 million viewers overall). CBS ran third in demos with a repeat of "CSI" (3.4/9 in 18-49, 12.3 million viewers overall).
Also in the hour, the Justice League episode of "Smallville" established season highs for the skein (2.3/6 in 18-49, 5.2 million viewers overall), which ranked second for its hour in men 18-34 (2.8/9).
At 9 o'clock, "Grey's Anatomy" (8.7/20 in 18-49, 21.9 million viewers overall) led in key demos over CBS' "CSI" (6.9/16 in 18-49, 21.3 million viewers overall), although both were down vs. their most recent firstrun perfs. NBC's "Scrubs" (2.9/7 in 18-49, 6.6 million viewers overall) was on the low end with a musical episode, and "30 Rock" (2.4/6 in 18-49, 5.1 million viewers overall) was below average as well.
It was another slow night for Fox's "Til Death" (2.1/6 in 18-49, 5.1 million viewers overall), "The War at Home" (1.9/5 in 18-49, 4.4 million viewers overall) and "The OC" (1.7/4 in 18-49, 3.9 million viewers overall), although "Death" logged its best score since late September.
At 10, a repeat "ER" on NBC (2.5/7 in 18-49, 6.1 million viewers overall) provided an opportunity for rival dramas "Shark" on CBS (4.4/12 in 18-49, 15.0 million viewers overall) and "Men in Trees" on ABC (3.7/10 in 18-49, 10.7 million viewers overall) to shine. "Shark" matched its best delivery to date in key demos while "Men" was a tick off its best score since moving behind "Grey's" on Nov. 30.
Preliminary 18-49 averages for the night: ABC, 5.6/14; CBS, 4.9/12; NBC, 3.2/8; Univision, 2.1/5; 
CW, 1.9/5; Fox, 1.8/5.
In total viewers: CBS, 16.2 million; ABC, 15.6 million; NBC, 7.2 million; Univision, 4.7 million; Fox, 4.3 million; 
CW, 4.3 million.
