Fast National ratings for Tuesday, Oct. 27, 2009.
Even in repeats, CBS' "NCIS" juggernaut appears difficult to contain, as more than 16 million viewers tuned in for a procedural encore on Tuesday night. However, while all of CBS' repeats did solid numbers overall, they suffered in the 18-49 demographic, allowing NBC to grab the night's demo title. 
Among adults 18-49, NBC did a 3.1 rating, best of the night in the key demo. The other networks came in a bunch, with ABC's 2.6 rating, FOX's 2.5 rating and the 2.4 rating for CBS all following closely. Only The CW trailed with a 0.5 rating.
Overall, though, CBS averaged an estimated 12.14 million viewers to go with a 7.8 rating/12 share. ABC was second with a 6.6/11 and 10,.72 million. NBC was third with a 5.2/8 and 8.45 million and FOX's 4.0/6 and 6.5 million took fourth. The CW was a distant fifth with a 0.8/1 and 1.14 million viewers on average.
As mentioned earlier, CBS won the 8 p.m. hour with a 10.0/16 for "NCIS," amazingly robust numbers for a repeat. NBC's "The Biggest Loser" was second overall with a 5.7/9 and won the hour in the 18-49 demo with a 3.4 rating. ABC was third with the holiday classic "It's the Great Pumpkin, Charlie Brown," which had a 5.0/8. The first hour of FOX's "So You Think You Can Dance" performance and elimination episode had a 4.3/7 for fourth. That left a CW "90210" repeat in fifth for the hour.
ABC moved into first at 9 p.m. with a 9.3/14 for "Dancing with the Stars." CBS' "NCIS: Los Angeles" repeat still did a 7.2/11. NBC's "The Biggest Loser" improved to a 6.0/9 in its second hour, winning the demo with a 4.0 demo rating. FOX's "So You Think You Can Dance" slipped in its second hour. A CW repeat of "Melrose Place" had a 0.6/1.
In the 10 p.m. hour, CBS' "The Good Wife" repeat still won overall with a 6.3/11. However, facing the reduced competition, ABC's "The Forgotten" improved to a 5.7/10 and won the hour in the 18-49 demo with a 2.0 rating. NBC's "The Jay Leno Show" was a distant third overall, but tied with "The Good Wife" in the demo with a 1.8 rating.
