'There is every reason for wanting to get to the bottom of Rupert Murdoch. It is arguable that he has done more than any modern individual to shape public life, policy, and conversation in those parts of the Anglosphere where his media interests either dominate or hold serious sway. His influence is richly textured, transformative. Beyond bringing a populist insouciance to his host of print and television properties, he is also unafraid of using his reach as a political weapon, a tactic used with such vehement ubiquity that governments pre-emptively buckle to what they suppose is the Murdoch line. Debate is thus distorted and circumscribed. Public anxiety is co-opted as a cynically exploited tool of sales and marketing.' (Introduction)
