According to UEFA, the Premier League is set to overtake the NFL as the highest-earning sporting league in the world in terms of media income by 2017.

European club football revenues equal 80 percent of the four major U.S. Sports combined -- NFL, MLB, NBA and NHL.

The Premier League signed a new £5.136 billion ($7.8 billion) British TV rights deal in February this year for the upcoming 2016-19 seasons, and UEFA reports that a "conservative increase" in international rights later this year could see English clubs surpass the media rights figures of NFL franchises in 2017.
