Two out of four divisional NFL playoff games notched record-setting ratings results in Nielsen-measured viewers.
The highly touted, fiercely competitive game featuring the Kansas City Chiefs and Buffalo Bills on CBS posted a massive 50.4 million viewers on Sunday -- the largest NFL audience ever outside the Super Bowl and conference championship.
It was the first divisional game ever to top 50 million -- and 10% higher than the same late Sunday afternoon divisional playoff game of a year ago.
The Saturday afternoon game was another close contest featuring two venerable NFL franchises -- the San Francisco 49ers vs. the Green Bay Packers -- earning 37.5 million viewers, up 31% versus the same game a year ago.
Two other earlier games on both days posted basically flat results. The game featuring the Detroit Lions vs. the Tampa Bay Buccaneers posted 37.12 million viewers on NBC -- down 5% from the same game a year ago. The Baltimore Ravens vs. the Houston Texans on ABC-ESPN reached 32.4 million viewers, up 0.3% versus a year ago.
Divisional game data does not include NFL playoff viewership on Walt Disney's ESPN+ and NBCU's Peacock.
