Until the formation of News Corporation in 1979, News Limited was the principal holding company for the business interests of Rupert Murdoch and his family. Since then, News Limited had been wholly owned by News Corporation. In 2004, News Corporation announced its intention to reincorporate to the United States. On 3 November News Corp Limited ceased trading on the Australian Stock Exchange; and on 8 November, News Corporation began trading on the New York Stock Exchange. On 28 June 2013, News Corporation was split into two separate companies. Murdoch's newspaper interests became News Corp, which was the new parent company of News Limited. The group adopted the new News Corp Australia name following the listing of the new News Corp on 1 July 2013.
