Despite it being a blowout, the Seattle Seahawks' win over the Denver Broncos averaged 111.5 million people, more than any television program in U.S. history, surpassing the 2012 game on NBC when the New York Giants beat the New England Patriots in a much closer game -- 111.3 million watched that Super Bowl. (Per TvNewser)
The game is also now the most-watched program on Fox, breaking the 111.0 million viewer mark for the 2011's Super Bowl, when the Green Bay Packers defeated the Pittsburgh Steelers. Fox's live stream of Super Bowl XLVIII averaged 528,000 viewers. According to Fox, that's the biggest live stream of a sporting event in history (a number that is hard to prove, though it would seem to top recent Summer Olympics and March Madness streams).
The ratings continue to show that the Super Bowl is a juggernaut unlike anything else on TV. Three of the last four Super Bowls have set TV ratings records. While most broadcast programming is losing viewers in an increasingly fragmented video landscape, football -- and the Super Bowl in particular -- remains untouched by the changes happening in the rest of the media industry.
