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.
List of One Day International cricket records
One Day International (ODI) cricket is played between international cricket teams who are Full Members of the International Cricket Council (ICC) as well as the top four Associate members. Unlike Test matches, ODIs consist of one inning per team, having a limit in the number of overs, currently 50 overs per innings – although in the past this has been 55 or 60 overs. ODI cricket is List-A cricket, so statistics and records set in ODI matches also count toward List-A records. The earliest match recognised as an ODI was played between England and Australia in January 1971; since when there have been over 4,000 ODIs played by 26 teams. The frequency of matches has steadily increased, partly because of the increase in the number of ODI-playing countries, and partly as the cricket boards of those nations seek to maximise their revenue with the increased popularity of cricket, a process that dates from the time of the Packer Revolution.
