Without trying to sound biased, I would say soccer, because it has had a profound impact on developed and underdeveloped nations around the world. The Fifa World Cup only strengthens my theory.

Soccer as it is called in north america, and football in Europe.. Note they are the same

football.and i mean the type of sports when the players actually play with a ball and kick it by their feet,not with an egg and they hold it with their hands.
