Fast National ratings for Wednesday, Oct. 14, 2009.

It was a very positive Wednesday for a number of shows, as NBC's "Mercy," FOX's "Glee" and ABC's "Modern Family" and "Cougar Town" all showed week-to-week ratings gains (albeit small). When the dust cleared, FOX scored a small ratings upset by winning the demo, though CBS dominated overall.
Among adults 18-49, FOX won the night with a 3.1 rating, nipping the 3.0 rating for CBS. ABC's 2.3 rating and the 2.1 rating for NBC followed in the all-important demographic. The CW trailed with a 0.9 rating.
Overall, though, CBS averaged an estimated 11.26 million viewers to go with a 7.2 rating/12 share. NBC was a distant second with a 4.9/8. FOX and ABC followed with a 4.4/7, with The CW's 1.4/2 good for fifth.
CBS won the 8 p.m. hour with a 4.8/8 for "The New Adventures of Old Christine" and "Gary Unmarried." NBC's "Mercy" was second with a 4.7/8, up by the slimmest of margins in both total viewers and in the 18-49 demographic. FOX's "So You Think You Can Dance" actually won the hour in the demo with a 2.8 rating and finished third overall. ABC's "Hank" and "The Middle" slipped slightly from last week to average a 4.2/7. The CW's "America's Next Top Model" was fifth with a 2.1/3.
"Criminal Minds" kept CBS in first at 9 p.m. with an 8.3/13. NBC's "Law & Order: Special Victims Unit" was up over last week and finished second with a 5.9/9. ABC's "Modern Family" and "Cougar Town" had a 5.4/9 overall for third, with both shows posting gains overall and in the demo. FOX's "Glee" had a 4.5/7 and did a 3.3 rating in the demo. That kept The CW in last with a "Melrose Place" repeat.
"CSI: NY" dominated the 10 p.m. hour with an 8.5/15, also winning the demo with a 3.2 rating. NBC's "The Jay Leno Show" took second. Yes, "Eastwick" continues to deal with the onus of being the rare 10 p.m. drama to finish below Leno, sliding to a 3.6/6.
