In the clash of two-hour reality competitions, NBC rode "America’s Got Talent" to a comfortable win in the Tuesday ratings, based on Nielsen overnights for the key 18-49 demo.

TVbytheNumbers.com reports that "Talent" was easily the top show of the night on broadcast, scoring a 2.2 average rating in viewers 18-49. "Talent" and NBC prevailed even as the show matched last week’s series low for a Tuesday installment.

Fox’s "So You Think You Can Dance" was the only one of the three franchise reality shows to record an uptick, rising one-tenth from last week to a 1.3 average in the 18-49 demo. ABC’s "Extreme Weight Loss" slipped two-tenths from its season high a week ago, notching a 1.1.

The rest of the prime-time programming on the Big 4 broadcast networks consisted of repeats, including CBS’s three drama reruns ("NCIS," 1.0 average in 18-49; "NCIS: Los Angeles," 0.9; and "Person of Interest," 0.7) — which left the Tiffany Network in fifth place among the broadcast nets.

For prime time overall, NBC’s 1.8 average in adults 18-49 led the way, followed by Univision (1.4 average), Fox (1.3), ABC (1.0) and CBS (0.8). The battle for total viewers was tighter, with NBC taking a narrow win by averaging 6.8 million, ahead of CBS (6.5 million), Fox (4.0 million), ABC (3.5 million) and Univision (3.5 million).
