After the cancellation of last year’s March Madness due to the coronavirus pandemic, this year’s highly anticipated tournament has been delivering plenty of excitement to college basketball fans across the country — and audiences have been tuning into the games more than anything else on live TV.

Per Inscape, of all the live, linear minutes watched on Vizio smart TVs from March 18-30, 6.94% of the time was spent with the NCAA men’s basketball tournament games, putting March Madness in first place for overall watch-time during that date range. The women’s tournament captured 0.61% of minutes watched, putting it in ninth place. 

Looking at the stages of the tournament, the first-round games on March 19-20 had the highest percentage of minutes watched (14.61%) compared to the other stages, which makes sense given the high number of games that aired those two days.
