International cricket
In addition to the one-day series and tournaments organised by the nations themselves, the ICC organises two One Day International tournaments. The World Cup is held every four years; it involves all the Test-playing nations and a number of teams advancing from the immediately preceding ICC World Cup Qualifier. The ICC Champions Trophy, previously known as the ICC Knockout Cup, is a shorter tournament held every four years in between World Cups. The ICC also organises a T20 International tournament, the ICC World Twenty20, which is generally held every two years and, as in the latest competition, involves the ten full ICC members and six associate members who qualified through a qualifier competition, the ICC World Twenty20 Qualifier.
Cricket World Cup
The World Cup is open to all members of the International Cricket Council (ICC), although the highest-ranking teams receive automatic qualification. The remaining teams are determined via the World Cricket League and the ICC World Cup Qualifier. A total of twenty teams have competed in the eleven editions of the tournament, with fourteen competing in the latest edition in 2015; the next edition in 2019 will have only ten teams. Australia has won the tournament five times, with the West Indies, India (twice each), Pakistan and Sri Lanka (once each) also having won the tournament. The best performance by a non-full-member team came when Kenya made the semi-finals of the 2003 tournament.
