1. Olympic Games
Location: Rotates (2016 Rio De Janeiro, Brasil)
Countries participating: 200+
TV audience: 4.8B viewers
Summary: Here we combine the Summer and Winter games, but there is no question that the Olympics are the singular worldwide sporting event that brings all countries to the table. There seems to be some event that every country is good at, and spectators love to watch all the action from Track to Swimming to Skiing to Figure Skating. In some ways, it’s become a made-for-TV event, but nobody seems to care.
