Meaning, at News Corp., Rupert Murdoch is the one guy who sets the parameters, who makes the decisions, and whose sensibility is stamped onto the brains of underlings. A producer on, say, Fox News, for good or ill, thinks about what Murdoch wants out of the programming a hell of a lot more than a producer for Time Warner's CNN thinks about Bewkes.
Permit me to introduce the One-Guy theory of media companies. A One-Guy company, to a remarkable degree, has one guy clearly in charge and setting the tone of the organization. Working at a truly One-Guy kind of place concentrates the mind wonderfully, as anyone who worked for ur-One-Guy guy Barry Diller will tell you.
