Sunday prime time on the broadcast networks looked like a sign of things to come during summer, when ratings are down significantly. TVbytheNumbers.com reports that two networks, ABC and Fox, tied for the lead for prime time overall by averaging 1.0 ratings in the key 18-49 demo, based on Nielsen overnights.

The best any individual program did was a 1.3 average in 18-49, with ABC's two-hour "The Bachelorette," Fox's "Cosmos: A Spacetime Odyssey" and a repeat of "Family Guy" on Fox all hitting that number as all of the big four broadcasters broke out repeat programming.

CBS's only fresh program was "60 Minutes," which managed a 0.9 in viewers 19-49. Fox's "Enlisted" launched its summer burn-off with a 0.4.

On NBC, a fresh installment of "Believe" improved two-tenths after a series low a week ago, inching up to a 0.9 in the 18-49 demo, and "Crisis" ticked up one-tenth to a 0.8 after a series low last week.

For prime time overall, ABC and Fox led the way in the 18-49 demo with 1.0 averages, ahead of NBC (0.9 average) and CBS (0.6). CBS had the edge in total viewers with 5.14 million, followed by NBC (4.12 million), ABC (4.11 million) and Fox (2.42 million).
