Ross McKibbin writes:
Rupert Murdoch has created perhaps the greatest media business in the history of the media business. It exceeds in scope any of the empires assembled by the Hearsts, the Harmsworths and the Thomsons. Murdoch himself seems driven by insatiable ambition. He is never satisfied. Nothing appears complete, and the old man shows no sign of abandoning the struggle – especially as his heirs (his children) now publicly quarrel over the patrimony. What makes Rupert run? Money, power, glory, the business itself?
