Madonna Louise Ciccone is an American singer-songwriter and actress. Known as the "Queen of Pop", Madonna has been widely recognized for her continual reinvention and versatility in music production, songwriting and visual presentation. She has pushed the boundaries of artistic expression in mainstream music, while continuing to maintain control over every aspect of her career. Her works, which incorporate social, political, sexual and religious themes, have generated both controversy and critical acclaim. A prominent cultural icon crossing both the 20th and 21st centuries, Madonna remains one of the most "well-documented figures of the modern age", with a broad amount of scholarly reviews and literature works on her, as well as an academic mini subdiscipline devoted to her named Madonna studies. With sales of over 300 million records worldwide, Madonna is the best-selling female recording artist of all time. She is the most successful solo artist in the history of the U.S. Billboard Hot 100 chart and has achieved the most number-one singles by a woman in Australia, Canada, Italy, Spain and the United Kingdom. With a revenue of over U.S. $1.5 billion from her concert tickets, she remains the highest-grossing female touring artist worldwide. Forbes has named Madonna the annual top-earning female musician a record 11 times across four decades (1980s–2010s). She was inducted into the Rock and Roll Hall of Fame in 2008, her first year of eligibility. Madonna was ranked as the greatest woman in music by VH1 and as the greatest music video artist ever by MTV and Billboard. Rolling Stone also listed her among its greatest artists and greatest songwriters of all time.
