90 million: Combined reach of the 20 brands Wintour oversees as artistic director

Why she matters: Wintour's perch drives home the point that magazine covers still matter, both in setting the national agenda and as marketing for actresses, actors and brands. And the tastemaker's actions are dissected ad nauseam. A move as innocent as sitting in the second row of a show can spark a frenzy, as it did at Valentino's Paris Fashion Week show, where the New York resident gave up a front-row seat to her web reporter.

Big get: Vogue's April issue with cover stars Kim Kardashian and Kanye West caused an outcry among fashion's faithful while generating a publicity bonanza and predicted newsstand sales of 300,000 to 400,000, well above the monthly 250,000-plus average.

Proudest accomplishment this year: In her first year as artistic director, Wintour, 64, had a big hand in the revitalized Lucky; she also has set her sights on Glamour, which debuted as a more fashion-focused publication with its March issue. Next on her list? The ailing Self, which in a masthead shake-up named Joyce Chang editor-in-chief in April. On the personal side, her daughter, Bee Shaffer, is a segment producer on NBC's Late Night With Seth Meyers, while her son, Charlie Shaffer, is preparing for a June wedding while in his second year of medical school at Columbia. In May, the Metropolitan Museum of Art will rename its Costume Institute the Anna Wintour Costume Center.
