Rupert Murdoch's News Corporation is the most powerful media organisation in the world. Murdoch's commercial success is obvious, but less well understood is his successful pursuit of political goals, using News Corp as his vehicle. David McKnight uncovers Murdoch's crusade for his unique brand of conservatism over three decades.

Rupert Murdoch's News Corporation is the most powerful media organisation in the world. Murdoch's commercial success is obvious, but less well understood is his successful pursuit of political goals, using News Corporation as his vehicle. David McKnight tracks Murdoch's influence, from his support for Reagan and Thatcher, to his attacks on Barack Obama and the Rudd and Gillard governments. He examines the secretive corporate culture of News Corporation: its private political seminars for editors, its sponsorship of think tanks and its recurring editorial campaigns around the world. Its success is reflected in the fact that the campaigns are familiar to us all: small government and market deregulation, skepticism on climate change, support for neo-conservative adventures such as Iraq and criticism of all things 'liberal'. While the phone hacking crisis has tarnished his reputation, Rupert Murdoch's influence is far from finished.
