Chiefs-Bills crowned most-watched AFC Championship game in history

Sunday’s thriller between the Kansas City Chiefs and Buffalo Bills was the most-watched AFC Championship game in NFL history.
The game averaged 57.4 million viewers on CBS, trumping last year’s record audience of 55.5 million who watched the Chiefs beat the Baltimore Ravens on the road.
Before that, the previous AFC Championship record was held by the 2011 renewal between the New York Jets and Pittsburgh Steelers (54.85 million).
The historic numbers were in large part thanks to the dramatic nature of the encounter, which went right down to the wire and saw the Chiefs narrowly hold on to a 32-29 victory.
It wasn’t without controversy either when the Bills gambled on a fourth-and-1 at the Kansas City 41-yard line in the fourth quarter and Josh Allen‘s quarterback sneak was ruled agonizingly short of the line to gain following a review.
At that point, Buffalo were clutching onto a 22-21 lead with 13 minutes to play and the entire momentum shifted towards the hosts who immediately cashed in on the turnover as Patrick Mahomes scrambled for a 10-yard touchdown and completed a successful 2-point conversion.

What is the most-watched conference championship game in history?
That title belongs to the 1982 NFC Championship game between the Dallas Cowboys and San Francisco 49ers, which drew in an unbelievable 68.7 million viewers.
If ‘out of home’ measurement, which tracks TV viewing in public places like bars, hotels and restaurants was included in that figure, it would’ve been well north of 75 million and potentially as big as 80.
