It was another sleepy Sunday for the broadcast networks last night, with CBS’ “Big Brother” easily the top draw in demos but nothing else doing much at all.

Early numbers for “Big Brother” are tentative since it started about 20 minutes late in most of the country due to a golf overrun and a full-duration “60 Minutes” that didn’t wrap until 7:20. In the preliminary Nielsen averages based on time periods, CBS averaged a 1.9 rating/6 share in adults 18-49 and 6.7 million viewers overall in the 8 o’clock hour — so “Big Brother” likely should round up to a 2.0 or 2.1 in the nationals, which would put it on par with last week.

From 7 to 8, the combo of golf and “60 Minutes” averaged a 0.8/3 in 18-49 and 5.7 million viewers overall on the CBS stations.

Fox edged out CBS on the night in 18-49 with repeats of its animated comedies: “The Cleveland Show” (0.8/3 in 18-49, 1.9 million viewers overall), “The Simpsons” at 7:30 (1.0/4 in 18-49, 2.2 million viewers overall) and then at 8 (1.2/4 in 18-49, 2.7 million viewers overall), “Bob’s Burgers” (1.0/3 in 18-49, 2.4 million viewers overall), “Family Guy” (1.5/5 in 18-49, 3.3 million viewers overall) and “American Dad” (1.4/4 in 18-49, 3.1 million viewers overall).

At ABC, a repeat of “America’s Funniest Home Videos” (0.9/3 in 18-49, 4.9 million viewers overall) was followed by unscripted series “Celebrity Wife Swap” (1.2/4 in 18-49, 3.5 million viewers overall) and “Whodunnit?” (1.1/3 in 18-49, 3.1 million viewers overall), both of which remain low but were up week to week. Closing the night was a repeat of “Castle” (0.7/2 in 18-49, 3.0 million viewers overall).

NBC went with repeats of “America’s Got Talent” (0.8/3 in 18-49, 4.1 million viewers overall) and “Law & Order: SVU” (0.7/2 in 18-49, 3.4 million viewers overall) and an original episode of struggling firstrun drama “Crossing Lines” (0.5/2 in 18-49, 2.9 million viewers overall), which appears to have hit a low.
