Heading into the Final Four of the 2026 NCAA Tournament, TV ratings continue to rise, CBS Sports and TNT Sports said. The Sweet 16 and Elite 8 also delivered for the networks.

Through the first two weekends of March Madness, viewership is up 9% and on track to be the most-watched tournament since 1993. Of course, part of that increase can be attributed to Nielsen’s Big Data + Panel measurement, which debuted last fall. But CBS and TNT Sports are still getting big TV ratings wins as part of a strong year for college basketball.
