CBS Sports continued its record-setting pace Sunday, delivering the network’s largest Week 9 NFL audience since the league returned to CBS in 1998, highlighted by the Chiefs-Bills matchup that drew nearly 31 million viewers.
The 4:25 p.m. ET kickoff between the Kansas City Chiefs and Buffalo Bills became the most-watched “NFL on CBS” Week 9 game since 2007, when the 8-0 New England Patriots faced the 7-0 Indianapolis Colts.
According to Nielsen Big Data + Panel, the game attracted 30.838 million viewers, representing a 25% increase over last year’s comparable week, which featured the Philadelphia Eagles at Dallas Cowboys on November 10.
Buffalo’s victory also became the most-watched program of the week on any network, peaking at 35.199 million viewers. Sunday’s NFL doubleheader averaged 24.424 million viewers, marking CBS Sports’ strongest Week 9 viewership since the league returned to the network more than two decades ago.
Earlier in the day, the Colts-Steelers matchup at 1:00 p.m. ET recorded 18.556 million viewers, setting the network’s most-watched Week 9 regional game window since 1998. The combination of the doubleheader and the prime-time matchup contributed to CBS Sports achieving its best NFL viewership season-to-date since 1998, averaging 19.419 million viewers, up 6% from the same point last year.
The Week 9 surge follows CBS Sports’ broader strategy of pairing marquee matchups with consistent production quality, including on-air analysis from seasoned commentators and integration of interactive features across digital platforms.
The Chiefs-Bills game, in particular, benefited from both teams’ high rankings in the AFC and a late-season playoff narrative that has captured national attention over the past years.
