The overnight rating for the NFC Championship game between the 49ers and Falcons on Fox was a 26.1, down 10% from last year's Patriots-Ravens matchup on CBS in the early slot and down 13% from 2011's Packers-Bears game on Fox. That 26.1 is the lowest overnight for the early timeslot since Cardinals-Eagles in 2009. The only other early game this decade to have a lower overnight than either of those two games is 2006's Steelers-Broncos matchup.
Not to be outdone, the AFC Championship game between the Ravens and Patriots in the later timeslot was also down in comparison from last year, drawing a 27.9 overnight, which fell 17% from the Giants-49ers game on Fox from last year. It's also the lowest rating for the late timeslot since (once again) 2009, when the Steelers and Ravens drew a disappointing 23.8 overnight. Perhaps even more disappointing is that despite being in the primetime timeslot, the AFC Championship game overnight decreased by 4%, even with the exact same teams as last season.
The NFL is still having a monstrous ratings season. Both of the games this weekend drew at least 40 million viewers (42.0 million for 49ers-Falcons, 47.7 million for Ravens-Patriots), viewership numbers that only the NFL has touched since the Summer Olympics ended. But the trend of ratings dropping this year on Fox and CBS continued this weekend.
