The third presidential debate proved to be a record-setter for Fox News. Nielsen says 11.5 million people watched on the channel, making it the network's most-watched show ever, reports AP. Overall, 59.2 million checked in, down from debates one (67.2 million) and two (65.6 million), reports TVNewser. It didn't help that No. 3 competed with two big sports events—Monday Night Football (10.7 million) and the baseball playoffs (8.1 million).
