The Kansas City Chiefs' 32-29 win Sunday over the Buffalo Bills was the most-watched AFC Championship game in history with 57.4 million viewers on CBS, according to the Sports Business Journal.

Austin Karp of the Sports Business Journal reported Tuesday that the Chiefs’ 32-29 win over the Bills was seen by 57.4 million people on television. A year go, the Chiefs’ 17-10 win over the Ravens set a record with 55.5 million viewers. That number was topped by nearly 2 million viewers on Sunday.

The Pittsburgh Steelers might not be playing in the AFC Championship game but plenty of fans will be watching the showdown between the Kansas City Chiefs and Buffalo Bills. Unfortunately, the Steelers were once again one and done in the playoffs after losing to the Baltimore Ravens 28-14.
