The bowler, a player from the fielding team, bowls a hard, fist-sized cricket ball from the vicinity of one wicket towards the other. The ball usually bounces once before reaching the batsman, a player from the opposing team. In defence of the wicket, the batsman plays the ball with a wooden cricket bat. Meanwhile, the other members of the bowler's team stand in various positions around the field as fielders, players who retrieve the ball in an effort to stop the batsman scoring runs, and if possible to get him or her out. The batsman — if he or she does not get out — may run between the wickets, exchanging ends with a second batsman (the "non-striker"), who has been waiting near the bowler's wicket. Each completed exchange of ends scores one run. Runs are also scored if the batsman hits the ball to the boundary of the playing area. The match is won by the team that scores more runs.
Cricket has been an established team sport for hundreds of years and is thought to be the second most popular sport in the world. More than 100 countries are affiliated to the International Cricket Council, cricket's international governing body. The sport's modern form originated in England, and is most popular in the present and former members of the Commonwealth. In many countries including India, Pakistan, Bangladesh, Sri Lanka and Australia, cricket is the most popular sport. It is also a major sport in England, New Zealand, South Africa, Zimbabwe and the English-speaking countries of the Caribbean, which are collectively known in cricketing parlance as the West Indies. Many countries also have well-established amateur club competitions, including the Netherlands, Kenya, Nepal and Argentina.
The sport is followed with passion in many different parts of the world. It has even occasionally given rise to diplomatic outrage, notoriously the Basil D'Oliveira affair (which led to the banning of South Africa from sporting events) and the Bodyline Test series in the early 1930s (which led to a temporary deterioration in relations between Australia and the United Kingdom).
The aim of the batting team is to score as many runs as possible. A run is scored when both batsmen successfully move to their respective opposite ends of the pitch. (The batsmen will usually only attempt to score runs after the striker has hit the ball, but this is not required by the rules—the batsmen can attempt runs at any time after the ball has been bowled.) Runs are also scored if the batsman hits the ball to the boundary of the playing area (this scores six runs if the ball crosses the boundary without having touched the ground, or four runs otherwise), or if the bowler commits some technical infringement like bowling the ball out of reach of the batsman.
The aim of the bowler's team is to get each batsman out (this is called a "taking a wicket", or a "dismissal"). Dismissals are achieved in a variety of ways. The most direct way is for the bowler to bowl the ball so that the batsman misses it and it hits the stumps, dislodging a bail. While the batsmen are attempting a run, the fielders may dismiss either batsman by using the ball to knock the bails off the set of stumps to which the batsman is closest before he has grounded himself or his bat in the crease. Other ways for the fielding side to dismiss a batsman include catching the ball off the bat before it touches the ground, or having the batsman adjudged "leg before wicket" (abbreviated "L.B.W." or "lbw") if the ball strikes the batsman's body and would have gone on to hit the wicket. Once the batsmen are not attempting to score any more runs, the ball is "dead", and is bowled again (each attempt at bowling the ball is referred to as a "ball" or a "delivery").
