The 50-over World Cup is cricket's flagship tournament, usually played every four years, and involves the best teams around the globe. It has been held 11 times since 1975. This is not to be confused with the T20 World Cup, previously called the World Twenty20, which is also global competition. Like in the case of the Cricket World Cup, the T20 World Cup is organized by the International Cricket Council (ICC) - the world governing body for the game - with the key difference being it is played in the 20-over format.
