The Week 11 AFC showdown between the Buffalo Bills and Kansas City Chiefs drew the largest television audience for an NFL regular-season game in 17 years, not including holiday games.
Accordingly Kickoff at 4:25 p.m. EST on CBS reached 31.2 million viewers.
That's the most attendance for a regular season game since 2007, when Tom Brady and the New England Patriots faced Peyton Manning and the Indianapolis Colts in Week 9. Both teams were 8-0.
17 years later, the world saw the new version of the Brady-Manning rivalry as Josh Allen's Bills took on Patrick Mahomes' Chiefs. The Chiefs entered the game 9-0, while the Bills were 8-2.
With the Bills' win, Allen and Mahomes are now 4-4, with plenty of close games, monumental moments and highlight plays. The NFL would be happy with the TV ratings if these teams met again in the playoffs this season.
CBS also posted its largest regional window audience since 1992 in Week 11, drawing 19.8 million viewers to the Ravens-Steelers game.
It's safe to say it was a great day for the NFL and its fans.
