Vogue is growing up. The fashion bible entered the digital age on Thursday, launching its first iPad app called Vogue Cover Exclusive. The 99 cent app currently features the magazine’s Lady Gaga cover story, along with behind-the-scenes interviews and videos that are only available on the iPad. “With the Cover Exclusive app, we have created a custom brand of journalism targeted at the Twitter generation,” said Vogue’s Editor-in-chief Anna Wintour.
