Audiences didn’t show any real interest in Sunday’s two firstrun broadcast offerings, as both NBC’s series premiere of “Merlin” and ABC’s opening night of two-part movie “Impact” settled for scrawny ratings.

Fox fared best in demos with its animated comedy repeats, while CBS drew the most viewers overall on the night.

According to preliminary nationals from Nielsen, NBC’s two-hour premiere of “Merlin” averaged a projected 1.3 rating/4 share in adults 18-49 and 5.3 million viewers overall from 8:09 to 10:09 p.m., starting nearly 10 minutes late in much of the country due to a U.S. Open golf overrun. The golf action had put the Peacock into the early lead on the night, averaging roughly a 1.7/6 in 18-49 and 6.3 million viewers overall from 7 to 8:09 p.m. Closing out the evening for NBC was a repeat of “Law & Order: Special Victims Unit” (1.2/4 in 18-49, 4.3 million viewers overall).

At ABC, original movie “Impact” averaged a 1.2/3 in adults 18-49 and 4.8 million viewers overall from 9 to 11 p.m., but it did build a bit in its second hour. Meteor pic, starring David James Elliott and Natasha Hendridge, concludes next Sunday. Earlier on for the Alphabet network, the return of “Just for Laughs” didn’t do much at 7 o’clock (0.6/2 in 18-49, 2.8 million viewers overall), but things picked up some with encores of “America’s Funniest Home Videos” (0.9/3 in 18-49, 3.5 million viewers overall) and “Extreme Makeover: Home Edition” (1.1/4 in 18-49, 3.9 million viewers overall).

Fox didn’t garner a large overall audience on the night but did reasonably well among the under-50 crowd with repeats of its comedies including “Family Guy” (2.2/7 in 18-49, 4.3 million viewers overall), “The Simpsons” (1.8/6 in 18-49, 3.9 million viewers overall) and “American Dad” (1.8/5 in 18-49, 3.6 million viewers overall).

At CBS, “60 Minutes” (1.0/4 in 18-49, 8.1 million viewers overall) was competitive in demos kicking things off and stood as the night’s most-watched program overall. An original “Million Dollar Password” at 8 o’clock pulled a 1.1/4 in 18-49 and 6.4 million viewers overall.

Preliminary 18-49 averages for the night: Fox, 1.5/5; NBC, 1.4/5; CBS, 1.2/4; ABC, 1.0/3; Univision, 0.6/2; CW, 0.3/1.

In total viewers: CBS, 7.0 million; NBC, 5.3 million; ABC, 4.1 million; Fox, 3.1 million; Univision, 1.5 million; CW, 0.9 million.
