How many magazine lives does Tina Brown have? John Huey, the recently installed editor-in-chief of Time Inc., has lately been mulling over pushing out Jim Kelly, the managing editor of the company’s namesake title for the past five years. In addition to considering Newsweek’s Jon Meacham, Slate’s Jacob Weisberg, And Michael Kinsley, Huey’s been doing due diligence on Brown, floating the idea in conversations—though insiders insist he’s not serious about her. Brown, having failed to become Barbara Walters for her second act, is spending her time on a book about Princess Di and fighting to save her maisonette’s garden from a developer. Like the network-anchor search, this one is for an Establishment media prestige job with lots of Internet, cable news, and demographic worries. Dawn Bridges, spokeswoman for Time Inc., downplayed the replacement talk as “speculation,” though she noted that part of Huey’s job was to talk to people like Brown (though Brown says she hasn’t talked to him). Kelly, whose magazine won for General Excellence at last week’s National Magazine Awards, adds, “I’m not worried about my job. I’m not going anywhere.” Next: Elliman-Corcoran Broker War
