The shortened format was initially introduced to bolster crowds for the domestic game, and was not intended to be played internationally, but the first Twenty20 International took place on 17 February 2005 when Australia defeated New Zealand, and the first tournament was played two years later, with the introduction of the ICC T20 World Cup. In 2016, for the first time in a calendar year, more Twenty20 International matches (100) were played than ODI matches (99). As of 3 May 2019, 80 nations feature in ICC T20I team rankings.
