Football

This is, without a doubt, the most famous sports in the world. With an active following 200 countries, Association football’s popularity is unrivalled with any other sport. The recent 2018 FIFA World Cup got a viewership of almost 3.3 billion across the globe. That’s more than 40% of the world population. 

A game of association football or simply football is played between two teams of 11 players each. Both sides try to outscore one other in two halves of 45 minutes each. If the scores are level, the match either finishes as a draw or goes into extra time, of halves of 15 minutes each, depending on the format of the tournament. The penalty shoot-out is finally used to separate the teams if they are level at the end of 120 minutes. Of all the sports on this list, association football is the only one to use the actual clock. Therefore, the game finishes within a fixed time.
