Big Bang Theory Series Finale Ratings

It all ended with a big bang, too.

CBS’ The Big Bang Theory very ceremoniously ended its 12-season run on Thursday night before an audience of 18 million total viewers, while scoring a 3.1 demo rating.

Surging 43 and 55 percent week-to-week, those numbers mark more than a 3-1/2 year high in audience (since 9/21/15), while matching a 1-1/2 year high in the demo.

TVLine readers gave the long-running hitcom’s swan song an average grade of “A-.” You can dive into TVLine’s unrivaled, in-depth (and not yet finished) coverage here.

Leading out of that, Young Sheldon (13.7 mil/2.2, TVLine reader grade “A-“) hit 16- and 15-month highs with its sophomore finale, while the Big Bang retrospective did 11.8 mil and a 1.8. Capping CBS’ big night, S.W.A.T.’s finale (6 mil/0.9) hit and tied season highs.
