Even with its two-hour "America’s Got Talent" shedding viewers from last week, NBC coasted to an effortless ratings win Tuesday night, based on Nielsen overnights for the key 18-49 demo.

TVbytheNumbers.com reports that "Talent" ticked down one-tenth of a ratings point in viewers 18-49, settling for a 2.7 average — still the strongest show of the night on broadcast by a wide margin. NBC led off with a repeat of "Hollywood Game Night," which delivered a 1.0.

The other big two-hour reality showpieces airing last night couldn’t compete with NBC’s entry. Fox’s "So You Think You Can Dance" was next in line with a 1.4 average in the 18-49 demo, equaling last week’s number, while ABC’s "Extreme Weight Loss" also matched last week, notching a 1.1.

CW broke out its new show "Capture," which has been billed as a reality version of "The Hunger Games" (while critics liken it more to Hide and Seek). The one-hour premiere barely moved the needle at 9 p.m., trickling in with a 0.4 in viewers 18-49 — well below CW’s two installments of "Whose Line Is It Anyway?" (0.8 at 8 p.m. and 0.9 at 8:30). "Capture" did improve on the 0.3 delivered by "Perfect Score" in the slot one week ago.

CBS rolled out three hours of drama repeats — "NCIS" (1.1 average in 18-49), "NCIS: Los Angeles" (0.9) and "Person of Interest" (0.8).

When the dust settled, NBC was firmly at No. 1 for prime time as a whole with a 2.1 average rating in 18-49, topping Fox (1.4 average), Univision (1.3), CBS (0.9), ABC (0.9) and CW (0.6). NBC’s edge in total viewers was 7.6 million to CBS’s 6.2 million, Fox’s 4.1 million, Univision’s 3.4 million, ABC’s 3.3 million and CW’s 1.7 million.
