47. Rupert Murdoch

Title: Executive chairman, 21st Century Fox and News Corp.

Country: Australia

Age: 84

Though he announced in June that he'll be stepping down as CEO of 21st Century Fox, the media company he cofounded, Rupert Murdoch will stay on as the executive chairman of one of the largest mass-media empires in the world.

Murdoch has recovered from the 2011 News Corp. phone-hacking debacle, which The Economist suggests may have even left him better off since he and his family have more than doubled their wealth since the scandal. He's now worth $13 billion. The Australian media mogul remains hungry for premier media properties, buying a majority stake in the established nature magazine National Geographic in September. He wasted no time cutting staff by 9%.
