World Series Cricket was a professional cricket competition that took place from 1977 to 1979. It was founded by Australian cricketer Kerry Packer in response to the traditional cricket structure, aiming to attract more viewers and generate revenue. The series featured international players and introduced innovations like colored clothing, day-night matches, and white cricket balls. The tournament included teams from Australia, England, and the West Indies, and it significantly changed the landscape of cricket. World Series Cricket helped popularize limited-overs formats and laid the groundwork for future competitions, ultimately influencing the development of modern cricket leagues worldwide.
