Last year, the Super Bowl drew a little over 100 million viewers, a dip from the 2018 Super Bowl. Meanwhile, the Champions League final between Liverpool and Real Madrid drew 480 million viewers worldwide. According to sources, only about 2 million of Champions League viewers were located in the United States, and the broadcast was available in more than 200 countries. By comparison, the Super Bowl is available in 180 countries, and anywhere from 30 million to 50 million viewers outside the U.S. watch. That number is not particularly likely to increase, even when considering the NFL’s recent marketing pushes in the U.K. and Mexico.
