According to NBC, Super Bowl XLIX drew a 49.7 household rating and a 72 percent share. Both numbers are higher than last year's overnight ratings of 47.6 and 70 for the Seahawks' win over the Denver Broncos.
NBC also said the game's viewership peaked just after 10 p.m.
The final ratings for Super Bowl XLIX will be announced later on Monday. Last year's game set a Super Bowl record with 112.19 million viewers.
