The Big Bang Theory is still one of the highest-rated shows on broadcast; it's set to go until at last the season after this upcoming one, and there's also now a single-cam prequel spin-off. It really defines CBS's comedy brand, and its ratings provide a halo to the next couple shows that air after it. That being said, it had its worst year in A18-49 relative numbers since the 2012-13 season. It did hit some relatively ugly data points later on, though on the bright side it rose for its finale. It wasn't down much more than the average show, but as a multi-cam comedy that's actually kind of disappointing.
Grade: B-
