Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American singer, songwriter, dancer, and philanthropist. Dubbed the "King of Pop", he is regarded as one of the most significant cultural icons of the 20th century, becoming the best-selling solo music act of all time. Over a four-decade career, his vast contributions to music, dance and fashion, along with his publicized personal life, made him a global figure in popular culture. Jackson influenced artists across a variety of musical styles. Through his decorative singing and visual presentation, he popularized street dance moves such as the moonwalk, which he named, the robot, and the anti-gravity lean. As the eighth child of the Jackson family, Michael made his public debut in 1964 with his older brothers Jackie, Tito, Jermaine, and Marlon as a member of the Jackson 5 (later known as the Jacksons). The Jackson 5 signed with Motown in 1968 and achieved worldwide success with Michael as lead singer. Jackson began his solo career in 1971 while at Motown and recorded several successful singles. He became a global solo star with his 1979 album Off the Wall.
