NBC used sports action, newsmagazine ”Dateline” and special repeats of ”America’s Got Talent” to earn a narrow victory among young adults over Univision on a very quiet night for the broadcasters.

NBC and Univision actually claimed the night’s top six broadcast programs in adults 18-49 , each earning a 1.2 rating in the demo , with the Peacock ruling outright in adults 25-54 and the Spanish-language leader alone on top in adults 18-34. CBS led comfortably in total viewers.

According to preliminary national estimates from Nielsen, NBC was steady throughout the night with coverage of the track and field U.S. Olympics Trials (1.2 rating/4 share in adults 18-49, 4.5 million viewers overall), followed by ”Dateline” (1.2/4 in 18-49, 5.2 million viewers overall) and encores of ”America’s Got Talent” at 9 p.m. (1.2/3 in 18-49, 4.5 million viewers overall) and 10 p.m. (1.2/3 in 18-49, 4.2 million viewers overall).

At Univision, talent show ”Pequenos Gigantes” (Little Giants) averaged a 1.2/4 in 18-49 and 3.5 million viewers overall from 8 to 10 p.m., and entertainment mag ”Sal y Pimienta” (Salt and Pepper) followed with similar numbers (1.2/3 in 18-49, 3.5 million viewers overall).

ABC hung in there, even with all repeats, of ”America’s Funniest Home Videos” (1.0/4 in 18-49, 4.5 million viewers overall), ”Secret Millionaire” (1.1/3 in 18-49, 3.8 million viewers overall) and ”Extreme Makeover: Weight Loss Edition” (0.9/2 in 18-49, 2.7 million viewers overall). The net didn’t schedule originals because Sunday could have been Game 6 of the NBA Finals (which instead wrapped on Thursday).

CBS aired ”60 Minutes” (1.0/3 in 18-49, 8.1 million viewers overall), followed by repeats of dramas ”Person of Interest” (0.7/2 in 18-49, 5.3 million viewers overall), ”The Good Wife” (0.6/2 in 18-49, 4.4 million viewers overall) and ”The Mentalist” (0.8/2 in 18-49, 5.1 million viewers overall).

And Fox went with repeats of ”American Dad” (0.6/2 in 18-49, 1.6 million viewers overall) and ”The Cleveland Show” (0.8/3 in 18-49, 1.7 million viewers overall) in the opening hour, and then replayed the two-hour special ”Fox’s 25th Anniversary Special” (0.9/3 in 18-49, 2.3 million viewers overall) from April.

Preliminary 18-49 averages for the night: NBC, 1.2/4; Univision, 1.1/3; ABC, 1.0/3; Fox, 0.8/3; CBS, 0.8/2.

In total viewers: CBS, 5.1 million; NBC, 4.2 million; Fox, 3.7 million; Univision, 3.1 million; ABC, 2.8 million.
