Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American singer, songwriter, dancer, and philanthropist. Dubbed the "King of Pop", he is widely regarded as one of the most culturally significant figures of the 20th century. His musical achievements broke American racial barriers and made him a dominant figure worldwide. Through his songs, music videos, concerts, and fashion, he transformed visual performance in popular music, popularizing street dance moves such as the moonwalk, the robot, and the anti-gravity lean. Jackson is often deemed the greatest entertainer of all time.[nb 1] The eighth of ten children in the Jackson family, he made his public debut at age six as the lead singer of the Jackson 5. Jackson rose to solo stardom with Off the Wall (1979) and achieved unprecedented global success with Thriller (1982), the best-selling album in history. The music videos for "Thriller", "Beat It", and "Billie Jean" redefined the medium. Bad (1987) was the first album to produce five US Billboard Hot 100 number-one singles: "I Just Can't Stop Loving You", "Bad", "The Way You Make Me Feel", "Man in the Mirror", and "Dirty Diana". Dangerous (1991) and HIStory (1995) were also successful. Jackson's final album, Invincible (2001), is the most expensive ever made.
