The Cowboys-Giants game on NBC earned the highest overnight rating in the six-year history of Sunday Night Football on NBC, according to overnight data released today by The Nielsen Company. Last night’s game on NBC, in which the Giants defeated the Cowboys, 31-14, to win the NFC East, registered a 17.1 overnight rating and a 27 share, 36 percent higher than last year’s Week 17 game (Rams-Seahawks, 12.6/19), which was also a win-and-in game to determine the winner of the NFC West, and topped the previous high Sunday Night Football overnight by one percent (Cowboys-Jets, 16.9/27 in Week 1 this season). Last night’s Sunday Night Football broadcast won the highest-rated program of the night. NBC led the night among metered markets in primetime (7-11 p.m. ET) with a 12.9/21, topping the 7.5/12 for CBS, which was boosted by an NFL overrun. NBC also beat Fox (3.0/5) by 330 percent and ABC (2.5/4) by 416 percent.
