Madonna is known for exploring religious symbolism and sexual themes in her work. This drew criticism from the Vatican throughout the 1980s. In 1992, she founded an entertainment company, Maverick, which published a book of erotic photographs called Sex. She also released a similar themed studio album called Erotica and starred in a film called Body of Evidence. These works generated negative publicity and coincided with a fall in commercial sales in the 1990s. Madonna's career was revived in 1998, when the release of her seventh studio album Ray of Light garnered critical acclaim.
Madonna has acted in 22 films. Although most failed critically and commercially, she earned a Golden Globe Award for her role in the 1996 film Evita. Divorced from actor Sean Penn, Madonna has a daughter, Lourdes, by her former personal trainer Carlos Leon. She also has two sons with former husband Guy Ritchie, one of whom was adopted from Malawi, causing media allegations that they violated that country's adoption laws.
She has been regarded as "one of the greatest pop acts of all time" and dubbed the "Queen of Pop" by various sources. She is ranked by the Recording Industry Association of America as the best-selling female rock artist of the twentieth century and the second top-selling female artist in the United States with sixty three million certified albums. Guinness World Records list her as the world's most successful female recording artist of all time and the top-earning female singer in the world with an estimated net worth of US$490 million, having sold over two hundred million records worldwide. On March 10, 2008, she was inducted into the Rock and Roll Hall of Fame.
