Twenty20 cricket, sometimes written Twenty-20, and often abbreviated to T20, is a short form of cricket. At the professional level, it was originally introduced by the England and Wales Cricket Board (ECB) in 2003 for the inter-county competition in England and Wales.[1] In a Twenty20 game the two teams have a single innings each, which is restricted to a maximum of 20 overs. Together with first-class and List A cricket, Twenty20 is one of the three current forms of cricket recognised by the International Cricket Council (ICC) as being at the highest international or domestic level.
