Ratings: Broadcast Finals for August 17, 2012

The NFL on FOX was the highest rated program in the 18-49 demo graphic, but when it is only a 1.3, there really isn't much to brag about. its preseason football and unless you have a "Killer" match-up, not very many people care to watch.

ABC averaged the most viewers over the night with over 4.5 million viewers. Two hours of 20/20 did decent for the network, as did DATELINE for NBC.
