The gradual evolution of Network Ten into its current form has its origins in the ongoing attempts by media mogul Rupert Murdoch to acquire a prized commercial television licence in Australia's largest capital city market, Sydney. This began when Murdoch's News Limited purchased the Wollongong station WIN Television in the early 1960s, around the same time he bought Festival Records. In 1977, frustrated by regulatory blocks that prevented him from expanding into the Sydney market, Murdoch sold WIN and purchased a 46% share in Ten Sydney.
