3. Super Bowl
Location: Rotates (2015 Glendale, AZ, USA)
Countries participating: One
TV audience: 111M viewers almost all U.S.
Summary: While almost an exclusively United States event, it’s that big that it deserves this spot. By far the most watched TV show annually in the United States and it’s not even close. It’s so big the commercials are almost more watched than the game. Not to mention the halftime show.
