The Philadelphia Eagles won Super Bowl LIX over the Kansas City Chiefs in front of a record number of viewers.

The Super Bowl set an all-time record with a projected average audience of 126 million viewers on Sunday night, according to Fox Sports PR.

The network reported a peak audience of 135.7 million viewers in the second quarter of the Eagles' 40-22 win.

The Super Bowl also drew in record-high streaming viewership, including 13.6 million viewers watching on Tubi, according to Fox Sports.

By the time viewership reportedly peaked on Sunday, the result of the Super Bowl was already all but decided. The Eagles pulled out to a 24-0 lead through two quarters, and were leading by 34 points before the Chiefs finally scored late in the third quarter.

Struggles against the Eagles' defense didn't stop the Chiefs from making history. Kansas City's appearances in the last three Super Bowls reportedly coincided with three separate viewership records.

The Eagles and Chiefs' last matchup in Super Bowl LVII attracted an average of 115.1 million viewers to Fox Sports broadcasts in February 2023, according to Nielson and ESPN. That stood, at the time, as the most-watched U.S.-based telecast in history, per ESPN.

The Chiefs' matchup with the San Francisco 49ers in last year's Super Bowl LVIII set another record with 123.4 million average viewers across platforms including CBS and Paramount+, according to Nielsen and the NFL.

Now the record has been reportedly broken for a third straight year.

Prior to the Chiefs' run, the Super Bowl viewership record had been set in 2015 by the average of 114.4 million people watching Tom Brady and the New England Patriots defeat the Seattle Seahawks in Super Bowl XLIX, per ESPN.

NBC has the rights to three upcoming Super Bowls, including Super Bowl LX. The championship game for the 2025 season is set to take place in the San Francisco 49ers' Levi's Stadium in Santa Clara, California next February.
