Fast National ratings for Tuesday, December 22, 2009.
 
We know that CBS' "NCIS" has solidified its place as TV's most watched show this fall, but we still can't help but be amazed when "NCIS" repeats draw more than 15 million viewers on an otherwise dead Tuesday night. Only ABC showcased a limited amount of new programming and the absence of alternatives did nothing to help "Scrubs" and "Better Off Ted."
 
Among adults 18-49, CBS won the night with a 2.4 rating. NBC's 1.5 rating was second in the key demographic, followed closely by the 1.2 rating for ABC and FOX's 1.1 rating. The CW's 0.4 rating trailed.
 
Overall, CBS averaged an estimated 12.24 million viewers to go with a 7.8 rating/13 share. No other network was close. NBC finished second with a 3.0/5 and averaged under 4.59 million viewers. ABC's 2.6/4 and FOX's 2.5/4 weren't fare behind. The CW was fifth with a 0.6/1.
 
CBS swept the primetime hours starting at 8 p.m. with the 9.7/16 for "NCIS," which also had a 2.9 demo rating, the night's best. ABC's "America's Funniest Home Videos" was second. NBC's repeat of a "Biggest Loser" special was third with a 2.8/5, beating the 2.4/4 for FOX's encore of Carrie Underwood's Christmas special. The CW's "90210" repeat had a 0.7/1 for fifth.
 
"NCIS: Los Angeles" dropped to a 7.7/13 in the 9 p.m. hour, but kept CBS in first, also winning the hour in the demo with a 2.4 rating. NBC's "Biggest Loser" repeat had a 2.9/5 for second, with FOX's Carrie Underwood special in third. ABC's new "Scrubs" (2.3/4) and "Better Off Ted" (1.9/3 with under 2.88 million viewers) were fourth, better than the 0.4/1 for The CW's "Melrose Place" repeat.
 
"The Good Wife" closed primetime with a 5.9/10 for CBS, along with a 1.7 demo rating. NBC's "The Jay Leno Show" finished second with a 3.2/6. ABC's encore of "Christmas at the White House" was third.
