With CBS Tuesday flagship “NCIS” beating Fox Tuesday flagship “Glee” for the first time in adults 18-49, CBS was able to eke out a narrow win over Fox for the night overall, TVbytheNumbers.com reported. In total viewers, CBS dominated the night as it usually does.

CBS finished the night with a 3.4 average rating in the advertiser-coveted 18-49 demo, just ahead of Fox’s 3.2 average. Next in line was NBC with a 2.5 average, followed by Univision (1.6) and ABC (1.5). Total viewers was no contest, as CBS averaged 17.1 million for the night to Fox’s 7.8 million, NBC’s 6.8 million, ABC’s 4.7 million and Univision’s 3.9 million.

The narrow win by the long-running “NCIS” over “Glee” in their head-to-head battle at 8 p.m.–with “NCIS” averaging a 4.4 rating in 18-49 to “Glee’s” 4.3–was the first by the CBS crime procedural over the Fox musical comedy, Entertainment Weekly reported. “NCIS” typically wins the night in total audience, but the 18-49 demo is key to advertisers’ needs and programming decisions, the story points out.

On the other networks at 8 p.m., hour one of NBC’s "The Biggest Loser" collected a 2.4 in the 18-49 demo while ABC’s "No Ordinary Family" had a 1.4 and CW’s "One Tree Hill" had a 0.9 in 18-49.

At 9 p.m. CBS’s "NCIS: Los Angeles" led the way with a 3.9 in the 18-49 demo, over hour two of "The Biggest Loser" with a 3.1 in that demo. Fox’s "Raising Hope" and "Traffic Light" logged a 2.5 average and a 1.7, respectively, in the 18-49 demographic. ABC’s "V" had a 1.9 and CW’s "Hellcats" a 0.6, both in the same 18-49 demo.

The 10 p.m. hour was a win for NBC’s "Parenthood" with a 2.1 average rating, over CBS’s "The Good Wife," which netted a 1.9, both in the 18-49 demo. ABC’s "Primetime: What Would You Do?" trailed with a 1.4 in the same demo.
