Twenty20 cricket, sometimes written Twenty-20, and often abbreviated to T20, is a short form of cricket. It was originally introduced by the England and Wales Cricket Board (ECB) in 2003 for professional inter-county competition in England and Wales. In a Twenty20 game the two teams have a single innings each, which is restricted to a maximum of 20 overs. A typical Twenty20 game is completed in about three hours, with each innings lasting around 75–90 minutes and a 10–20-minute interval. This is much shorter than previously-existing forms of the game, and is closer to the timespan of other popular team sports. It was introduced to create a fast-paced form of the game which would be attractive to spectators at the ground and viewers on television. The ECB did not intend that Twenty20 would replace other forms of cricket (such as 40-50 over one day and multi-day first class formats), and these have continued alongside it.
