2025 College Basketball Postseason Week 1 Viewership

A full list of Nielsen measured viewership of College Basketball games from Week 1 of March Madness, Women's March Madness and the NIT

Here is a full list of television viewership for College Basketball for Week 1 of March Madness, Women’s March Madness and the NIT.

Viewership information for cable networks not measured by Nielsen (ESPNEWS, CBSSN, ACCN and SECN) and streaming services (ESPN+ and Peacock) are not available, along with select non-primetime over-the-air viewership numbers.

(Viewership is measured in terms of the “average audience”, or absolute number of viewers watching in an average minute of the game.)

(Note: I do my best to ensure these tables are as accurate as possible. However, college basketball scheduling can sometimes be strange and hard to follow. If I have messed up a matchup or missed a game on a Nielsen rated cable network, please let me know!)
