CBS won Sunday’s primetime ratings race thanks to “Big Brother,” which remains the night’s top series in demos, while ABC’s competing reality series “Bachelor in Paradise” edged up for a second straight week. Over at Fox, the “Teen Choice Awards” were on par with last year.

The CBS lineup started about 30 minutes late in much of the country due to a late-starting “60 Minutes” (1.5/6 in 18-49, 9.1 million viewers overall from 7:30 to 8:30 p.m.) that ran in its entirety following a golf overrun. Ratings for “Big Brother” are subject to change in the nationals, but its preliminary 2.0 rating in 18-49 (and 6.7 million viewers overall) from 8:30 to 9:30 p.m. is about average for the show’s Sunday edition.

At ABC, a repeat of “America’s Funniest Home Videos” (0.8/3 in 18-49, 4.9 million viewers overall) was followed by “Bachelor in Paradise” (1.3/4 in 18-49, 4.0 million viewers overall), with the latter up a tenth for a second straight week. “Bachelor,” which has also been picking up steam with its Monday installment, gave ABC strong time period improvement vs. last year, rising more than 60% above what “Wipeout” and “Rising Star” did from 8 to 10 on the comparable night a year ago.

Closing the night for the Alphabet, “Save My Life: Boston Trauma” (0.7/2 in 18-49, 3.3 million viewers overall) was up a tenth from last week.

Fox opened with encores of “Family Guy” at 7 (0.6/3 in 18-49, 1.5 million viewers overall) and 7:30 (0.8/3 in 18-49, 1.9 million viewers overall), followed by the “2015 Teen Choice Awards” (0.8/3 in 18-49, 2.6 million viewers overall), which matched its demo delivery of the previous two years and also was steady in total viewers. Sunday’s show, which was highlighted by Ellen DeGeneres’ acceptance speech and a tribute to the late Paul Walker, dominated the night in teens with a 2.5 rating/13 share.

According to Nielsen Twitter TV Ratings, Sunday’s telecast of the “Teen Choice Awards” led all programs for the week with about 3 million event-related Tweets, which were seen by a unique audience of 7.9 million people.

NBC aired a repeat of “Hollywood Game Night” (0.5/2 in 18-49, 2.2 million viewers overall), followed by the concert special “Ed Sheeran: Live at Wembley Stadium” (0.5/2 in 18-49, 2.1 million viewers overall) and a two-hour encore of “American Ninja Warrior” (1.0/3 in 18-49, 3.1 million viewers overall). “Ninja” was the broadcast leader in demos for the 10 o’clock hour.

Preliminary 18-49 averages for the night: CBS, 1.3/5; ABC, 1.0/4; Fox, 0.8/3; NBC, 0.7/3; Univision, 0.5/2; Telemundo, 0.3/1.

In total viewers: CBS, 6.8 million; ABC, 4.0 million; NBC, 2.3 million; Fox, 2.1 million; Univision, 1.6 million; Telemundo, 0.8 million.
