One day internationals

A One Day International (ODI) is a form of limited overs cricket, played between two teams with international status, in which each team faces a fixed number of overs, usually 50. The Cricket World Cup is played in this format. One Day International matches are also called Limited Overs Internationals (LOI), although this generic term may also refer to Twenty20 International matches. They are major matches and considered the highest standard of limited overs competition.

The international one-day game is a late twentieth-century development. The first ODI was played on 5 January 1971 between Australia and England at the Melbourne Cricket Ground. When the first three days of the third Test were washed out officials decided to abandon the match and, instead, play a one-off one day game consisting of 40 eight-ball overs per side. Australia won the game by 5 wickets. ODIs were played in white kits with a red ball.

In the late 1970s, Kerry Packer established the rival World Series Cricket competition, and it introduced many of the features of One Day International cricket that are now commonplace, including coloured uniforms, matches played at night under floodlights with a white ball and dark sight screens, and, for television broadcasts, multiple camera angles, effects microphones to capture sounds from the players on the pitch, and on-screen graphics. The first of the matches with coloured uniforms was the WSC Australians in wattle gold versus WSC West Indians in coral pink, played at VFL Park in Melbourne on 17 January 1979. This led not only to Kerry Packer's Channel 9 getting the TV rights to cricket in Australia but also led to players worldwide being paid to play, and becoming international professionals, no longer needing jobs outside of cricket. Matches played with coloured kits and a white ball became more commonplace over time, and the use of white flannels and a red ball in ODIs was finally abandoned in 2001.

In the main the Laws of cricket apply. However, in ODIs, each team bats for a fixed number of overs. In the early days of ODI cricket, the number of overs was generally 60 overs per side, and matches were also played with 40, 45 or 55 overs per side, but now it has been uniformly fixed at 50 overs.
