Keith Rupert Murdoch AC, KCSG, born in Melbourne, Victoria, Australia on 11 March 1931, is an Australian global media executive and is the controlling shareholder, chairman and managing director of News Corporation, based in New York City in the United States. Beginning with newspapers, magazines and television stations in his native Australia, Murdoch expanded into British and American media, and in recent years has become a powerful force in satellite television, the film industry, the Internet, and other forms of media.

He is one of the few chief executives of any multinational media corporation who has a controlling ownership share in the corporation. In Murdoch's case, it is via a family corporation.

Rupert Murdoch's Fox News Channel has been criticized by many liberal watchdog groups for what they state as it being politically conservative and advocating for conservative policies and candidates in its newscasts. They state that it is not "fair and balanced" as the network's tagline claims. The network is featured in the 2004 documentary Outfoxed described by Film Threat as "a shrill, one-note slam against a very easy target", which was produced and directed by liberal activist Robert Greenwald.
