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.
ICC T20 World Cup
The ICC T20 World Cup (earlier known as ICC World Twenty20) is the international championship of Twenty20 International cricket. Organised by cricket's governing body, the International Cricket Council (ICC), the tournament currently consists of 16 teams, comprising the top eight teams from the rankings at the given deadline and four other teams chosen through the T20 World Cup Qualifier. All matches are played as Twenty20 Internationals.
