Twenty20 is is a type of single innings cricket in which each team bats for a maximum of only 20 overs and closely resembles a form of the game which has been popular in English amateur cricket since at least the 1960s.
Twenty20 cricket was first introduced at county level by the England and Wales Cricket Board in 2003 and such was the success of the format of the sport, the game quickly spread around the world with the first men’s full Twenty20 international taking place in February 2005 between New Zealand and Australia.
