If you were watching the AFC Championship game on CBS over the weekend, then give yourself a pat on the back, because you were part of television history. The game between the Kansas City Chiefs and Buffalo Bills had an average audience of 57.

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.

After conspiring to deliver the biggest regular-season ratings for a Sunday NFL game this season, the Buffalo Bills and the Kansas City Chiefs reconvened last weekend for what would prove to be the most-watched AFC championship game on the books.
