Primetime Cable Ratings: September 16, 2015

The second Republican Presidential Debate was the most watched program on Wednesday night, commanding 23.1 million viewers and a solid 4.9 rating in Adults 18-49. The debate also posted a 4.0 in the A18-34 demo and a 6.0 in the older A25-54 demographic. It was CNN's most watched program in 30 years.

Not much else had a chance at decent ratings, unless you watched TBS reruns of THE BIG BANG THEORY or a kid watching Disney.
