Ratings: Shemar Moore’s ‘SWAT’ Premiere on CBS Tops at 10pm

“Big Bang Theory” and “Young Sheldon” also aid “Mom” and “Life in Pieces” returns

CBS just dropped “T.G.I.T.” and “Will & Grace” (and everything else) with its new-look Thursday lineup. The Les Moonves-led network also debuted Shemar Moore’s “S.W.A.T.” reboot in primetime, and brought back “Mom” and “Life in Pieces.”

All those premieres and time-period premieres tried to fill in the gaping hole left behind by “Thursday Night Football,” which CBS passed off to the NFL Network last night. NBC’s Thursday pigskin package starts next week.

It’s worth pointing out here that in New York City — the No. 1 media market in the country — CBS’ lineup was preempted for Thursday’s Buffalo Bills-New York Jets NFL game. The sheer size of that market (about 7 percent of the country) makes comparisons for the network particularly difficult, especially in these early Nielsen numbers. In all likelihood, the below CBS averages will decline a bit in final figures, rather than rise.

Either way, it’s clear that the second episode of “Young Sheldon” is down significantly from its highly promoted preview — as was the spinoff’s “Big Bang Theory” lead-in. A decline here was expected, though perhaps not to this degree.

Still, CBS was first in ratings with a 1.8 rating/7 share in the advertiser-coveted 18-49 demographic and in total viewers with an average of 9.9 million, according to preliminary numbers. “Big Bang” at 8 p.m. scored a 2.7/11 and 14.1 million viewers. At 8:30, “Young Sheldon” earned a 2.4/9 and 13.3 million viewers. The “Mom” season premiere at 9 posted a 1.8/7 and 9.6 million viewers. At 9:30, the “Life in Pieces” season premiere put up a 1.5/6 and 7.7 million viewers. The “S.W.A.T.” debut at 10 locked up a 1.3/5 and 7.5 million viewers.
