Ratings: NBC’s ‘AP Bio’ Premiere Doesn’t Quite Ace the Test

New Glenn Howerton sitcom — and its host network — finish fourth on Thursday

“A.P. Bio” didn’t exactly go to the head of its class with Thursday’s preview premiere, when the NBC sitcom finished fourth in ratings behind “Scandal,” “Life in Pieces” and “The Four.” The new Glenn Howerton-Patton Oswalt sitcom’s host network ended up in the same place for primetime averages among adults 18-49.

CBS was first last night, plugging in hits “The Big Bang Theory” and “Young Sheldon.” ABC and its “TGIT” lineup came in second place.

Last week, CBS had dropped from first to fourth with the low-rated NFL player talent show special, “MVP: Most Valuable Performer.” It’s good to be back to normal, we’re sure.

CBS was first in ratings with a 1.7 rating/7 share in the advertiser-coveted 18-49 demographic and in total viewers with an average of 9.3 million, according to preliminary numbers. “The Big Bang Theory” at 8 p.m. scored a 2.8/12 and 14.5 million viewers.
