NFL Viewership Reaches 35-Year High in 2025
The NFL’s 2025 regular season averaged 18.7 million viewers per game, a 10% year-over-year increase and the highest per-game average in over 35 years. All of the league’s media partners saw audience growth: NBC’s Sunday Night Football is pacing as primetime’s top show (23.5 million average), CBS recorded an 11% jump to its best season on record, and Amazon’s Thursday Night Football rose 16% to 15.3 million viewers. Nielsen’s updated measurement methodology — which better accounts for out-of-home viewing (e.g., bars) and ingests set-top box "big data" — contributed to the reported gains. The NFL’s international strategy also boosted reach, with viewership for six overseas games on NFL Network up 32% year-over-year. Publication date: 2026-01-12.
Large, cross-platform viewership gains for live sports shift advertising reach and pricing dynamics; Nielsen's measurement changes materially affect how live TV and streaming audience sizes are reported and planned against by advertisers, broadcasters and streaming platforms.

Nielsen: NFL Boosts Broadcast, Streaming Dominates
Nielsen’s October 2025 viewership report shows the NFL delivered a seasonal boost to broadcast TV but did not reverse its overall decline. Broadcast accounted for nearly 23% of total viewing in October and rose to over 27% on Sundays, while streaming’s total share grew to nearly 46%. Platforms with football rights — notably Peacock and Amazon Prime Video — posted notable gains, and non-sports streamers such as Netflix also saw increased Sunday viewership. Free ad-supported TV (FAST) channels like Tubi and Roku reported meaningful year‑over‑year growth. The report has prompted debate about measurement methodology, including controversy over YouTube’s inclusion in Nielsen’s metrics.
NFL Championship Weekend Hits Five-Year Viewership Low
Conference championship weekend viewership for the NFL dropped to a five-year low, with the AFC Championship on CBS drawing nearly 49 million viewers and the NFC title on Fox attracting about 46 million. Both games were down versus 2025’s higher-profile broadcasts (roughly 15% and 20% declines respectively). Observers attributed the dip to a lack of marquee quarterback matchups (neither Tom Brady nor Patrick Mahomes appeared) and to recent measurement rule changes that amplify the appearance of decline. Despite the weekend drop, the full postseason audience was reported up 5% year-over-year and CBS said it delivered its most-watched NFL season on record. The ratings conversation occurs amid an ongoing dispute between the NFL and Nielsen and broader questions about out-of-home viewing and weather impacts on audience measurement.
Football, Young Viewers Boost Broadcast TV in Q4
A Nielsen report shows ad-supported television peaked in Q4 2025, capturing nearly three-quarters of all TV viewing time. The ad-supported category grew 9% quarter-over-quarter (versus 7% for total TV), with streaming representing about 46% of ad-supported viewing. Broadcast television, however, experienced the largest uplift — a 22% jump in Q4 — driven almost entirely by football. Sports viewing on broadcast rose 135% and made up more than one-third of the ad-supported audience. Younger viewers returned to broadcast: people aged 25–34 increased viewing by 41%, and the 18–49 demo rose 31%. The data highlights live sports as a continuing, cross-generational audience driver for linear/broadcast channels and a key asset for advertisers and media owners.
