THR's 2012 Digital Power 50

Huffington, 61, started 2011 with a bang when she announced the sale of The Huffington Post to AOL for $315 million. She has since expanded local and international news coverage and launched new sites, such as HuffPo Science early in 2012, to fatten her one-stop shop. The Huffington Post in the third quarter surpassed 35 million monthly unique visitors, according to comScore, beating out The New York Times. Huffington also hired Michael Hogan, executive digital editor of Vanity Fair, as editor in chief of Moviefone and AOL TV, which at the end of 2011 was rebranded as HuffPost TV. Overall, "the vision is creating a great media company for the 21st century," Huffington tells THR.
