Successful cricketers often become lasting celebrities in Australia. Sir Donald Bradman, who made his Test debut in the 1928–29 series against England, is regarded as the game's greatest batsman and a byword for sporting excellence. Other Australian cricketers who remain household names include Richie Benaud, Dennis Lillee and Shane Warne and others who pursued media careers after they retired from the game. Internationally, Australia has for most of the last century sat at or near the top of the cricketing world. In the 1970s, Australian media tycoon Kerry Packer founded World Series Cricket from which many international forms of the game have evolved.
