Cricket entered a new era in 1963 when English counties introduced the limited overs variant. As it was sure to produce a result, limited overs cricket was lucrative and the number of matches increased. The first Limited Overs International was played in 1971 and the governing International Cricket Council (ICC), seeing its potential, staged the first limited overs Cricket World Cup in 1975. In the 21st century, a new limited overs form, Twenty20, made an immediate impact. On 22 June 2017, Afghanistan and Ireland became the 11th and 12th ICC full members, enabling them to play Test cricket.
The game on the field is regulated by the two umpires, one of whom stands behind the wicket at the bowler's end, the other in a position called "square leg" which is about 15–20 metres away from the batsman on strike and in line with the popping crease on which he is taking guard. The umpires have several responsibilities including adjudication on whether a ball has been correctly bowled (i.e., not a no-ball or a wide); when a run is scored; whether a batsman is out (the fielding side must first appeal to the umpire, usually with the phrase "How's that?" or "Owzat?"); when intervals start and end; and the suitability of the pitch, field and weather for playing the game. The umpires are authorised to interrupt or even abandon a match due to circumstances likely to endanger the players, such as a damp pitch or deterioration of the light.
A skilled batsman can use a wide array of "shots" or "strokes" in both defensive and attacking mode. The idea is to hit the ball to the best effect with the flat surface of the bat's blade. If the ball touches the side of the bat it is called an "edge". The batsman does not have to play a shot and can allow the ball to go through to the wicketkeeper. Equally, he does not have to attempt a run when he hits the ball with his bat. Batsmen do not always seek to hit the ball as hard as possible, and a good player can score runs just by making a deft stroke with a turn of the wrists or by simply "blocking" the ball but directing it away from fielders so that he has time to take a run. A wide variety of shots are played, the batsman's repertoire including strokes named according to the style of swing and the direction aimed: e.g., "cut", "drive", "hook", "pull".
Crickets are relatively defenceless, soft-bodied insects. Most species are nocturnal and spend the day hidden in cracks, under bark, inside curling leaves, under stones or fallen logs, in leaf litter, or in the cracks in the ground that develop in dry weather. Some excavate their own shallow holes in rotting wood or underground and fold in their antennae to conceal their presence. Some of these burrows are temporary shelters, used for a single day, but others serve as more permanent residences and places for mating and laying eggs. Crickets burrow by loosening the soil with the mandibles and then carrying it with the limbs, flicking it backwards with the hind legs or pushing it with the head.
In the visual arts, notable cricket paintings include Albert Chevallier Tayler's Kent vs Lancashire at Canterbury (1907) and Russell Drysdale's The Cricketers (1948), which has been called "possibly the most famous Australian painting of the 20th century." French impressionist Camille Pissarro painted cricket on a visit to England in the 1890s. Francis Bacon, an avid cricket fan, captured a batsman in motion. Caribbean artist Wendy Nanan's cricket images are featured in a limited edition first day cover for Royal Mail's "World of Invention" stamp issue, which celebrated the London Cricket Conference 1–3 March 2007, first international workshop of its kind and part of the celebrations leading up to the 2007 Cricket World Cup.
Cricket flour may be used as an additive to consumer foods such as pasta, bread, crackers, and cookies. The cricket flour is being used in protein bars, pet foods, livestock feed, nutraceuticals, and other industrial uses. The United Nations says the use of insect protein, such as cricket flour, could be critical in feeding the growing population of the planet while being less damaging to the environment.
