Overview
- The 2025 men's NCAA basketball tournament has drawn its largest audience through the first two rounds since 1993, averaging 9.4 million viewers across CBS, TNT, TBS, and truTV.
- Viewership for the men's tournament is up 4% from the same stage in 2024, with the Kentucky-Illinois matchup drawing a peak of 15.3 million viewers.
- The women's tournament, while down from 2024's historic highs, is maintaining strong ratings, outperforming every year since 2013.
- The inclusion of out-of-home impressions in Nielsen ratings and the rise of virtual MVPDs have significantly boosted reported viewership despite declines in traditional TV habits.
- The men's tournament has seen fewer upsets, with nearly all top-seeded teams advancing to the Sweet 16, a shift that has not dampened audience interest.
