Where Did the T20 Cricket format create

The first shorter form of cricket was created by New Zealand Test cricketer Martin Crowe in the 1990s

They called it Cricket Max in which each team played 10 eight-ball overs

Then Australia called it super 8s 

At the same time, England Cricket introduced the T20I which is the replacement for the Benson & Hedges Cup 

So every cricket national like T20 format and the first T20 International played on Feb 17, 2005

T20 format also helps to create Leagues Like IPL, BBL, PSL 

These leagues promote cricket on a high level and make cricket profitable
