 The book was an instant commercial success, managing to sell over 150,000 copies on its first day of release and topping the New York Times Best Seller list. It was received negatively by both critics and fans of the singer, who felt she had "gone too far." Through the years, however, critical reception towards Sex has become more positive, with academics deeming it a defining phase in Madonna's career. Sex is noted for its impact on society and culture as well as on Madonna herself, and is considered a bold, post-feminist work of art. The book has since become one of the most sought-after out-of-print books ever released and still remains the best and fastest-selling coffee table book of all time.
