In 2003, Weisberger's first book, "The Devil Wears Prada", was released and spent six months on the "New York Times" Best Seller List. The book is a semi-fictional but highly critical view of the Manhattan elite. As of July 2006, "The Devil Wears Prada" was the best-selling mass-market softcover book in the nation, according to "Publishers Weekly". The book is largely based on Weisberger's experience at "Vogue". There is much speculation that the character of Miranda Priestly represents aspects of Anna Wintour. The fictional Elias-Clark publishing company is said to be modeled after Condé Nast.
