UPDATE, 1:49 p.m. PT:
The numbers for Game 6 of the World Series are in, and as expected the baseball match-up scored the evening's top ratings, pushing Fox to a win for the night.
In the adults 18-49 demographic, the St. Louis Cardinals-Texas Rangers game drew a 5.6 rating, easily besting its closest competitor, CBS' "The Big Bang Theory," with an average viewership of 21.1 million total viewers. The game scored a 12.7 rating/21 share in household ratings, making it the highest-rated and most-watched game in the Fall Classic since Game 6 of the 2009 World Series.
With numbers from Game 6 of the World Series on Fox still pending, "The Big Bang Theory" holds the top ratings spot of Thursday night. NBC's comedy block suffered a series of losses, and "Prime Suspect" hit a series low, according to preliminary numbers.
"Big Bang" at 8 slid 12 percent from last week, but still towered over the competition, scoring a 4.5 rating/13 share in the adults 18-49 demographic and 14.2 million total viewers.
"Rules of Engagement" followed at 8:30, taking a 3.4/9 in the demo 10.7 million total viewers, while "Person of Interest" at 9 was down 4 percent for a 2.6/6 in the demo and 11.5 million total viewers.
"The Mentalist" closed the night at 10, performing flat with last week with a 2.5/6 in the demo and 12.2 million total viewers. The combined performances gave CBS an average 3.0/8 in the demo, which barring World Series results is currently the best performance for a network Thursday night, and an average 12 million total viewers -- also the highest ranking for the night as things now stand.
NBC's outlook was not nearly so rosy, with the network taking double-digit hits pretty much across the board. "Community" at 8 took an 18 percent hit from two weeks ago (the network ran repears last Thursday) to tie for its series low with a 1.4/4 in the demo and 3.4 million total viewers, while "Parks and Recreation" at 8:30 also tied for a series low, dropping 14 percent to a 1.8/5 in the demo and 3.8 million total viewers.
"The Office" at 9, meanwhile, hit its lowest numbers ever, slipping 15 percent to a 2.8/7 and 5.4 million total viewers. "Whitney" at 9:30 was the network's sole bright spot , climbing 5 percent for a 2.1/5 in the demo and 4.2 million total viewers. "Prime Suspect" closed the night at 10 with a series low, dropping 8 percent for a 1.2/3 in the demo and 4 million total viewers.
At ABC, "It's the Great Pumpkin, Charlie Brown" kicked off the night at 8, receiving a 5 percent boost over last year's telecast with a 2.3/6 in the demo and 7.3 million total viewers. "Grey's Anatomy" at 9 and "Private Practice" at 10 also posted modest gains, with the former scoring a 3.7/9 and 9.8 million total viewers, and the latter taking a 2.4/6 and 6.5 million total viewers.
