Michael Jackson one year on

The iconic and troubled singer Michael Jackson died one year ago today

In the early 1980s, Jackson became a dominant figure in popular music and the first African-American entertainer to amass a strong crossover following on MTV. The music videos for his songs, such as "Beat It", "Billie Jean" and "Thriller", were credited with transforming the medium into an art form and a promotional tool, and the popularity of these videos helped to bring the relatively new television channel to fame. Videos such as "Black or White" and "Scream" made him a staple on MTV in the 1990s. Through stage performances and music videos, Jackson popularized a number of dance techniques, such as the robot and the moonwalk. His distinctive musical sound and vocal style have influenced numerous hip hop, pop, contemporary R&B and rock artists. Jackson's album Thriller is the best-selling album of all time. His other records, including Off the Wall (1979), Bad (1987), Dangerous (1991) and HIStory (1995), also rank among the world's best-selling. Jackson is one of the few artists to have been inducted into the Rock and Roll Hall of Fame twice. His other achievements include multiple Guinness World Records; 13 Grammy Awards (as well as the Grammy Legend Award and the Grammy Lifetime Achievement Award); 26 American Music Awards (more than any other artist, including the "Artist of the Century"); 13 number-one singles in the United States in his solo career (more than any other male artist in the Hot 100 era); and the estimated sale of over 800 million records worldwide. Jackson won hundreds of awards, which have made him the most-awarded recording artist in the history of music. He was also a notable humanitarian and philanthropist, donating and raising hundreds of millions of dollars for beneficial causes and supporting more than 39 charities. Aspects of Jackson's personal life, including his changing appearance, personal relationships and behavior, generated controversy. In 1993, he was accused of child sexual abuse, but the case was settled and no formal charges were brought. In 2005, he was tried and acquitted of further sexual abuse allegations and several other charges after the jury ruled him not guilty on all counts. Amidst the preparations for the concert series This Is It, Jackson died on June 25, 2009, after suffering from cardiac arrest. Before his death, Jackson had reportedly been administered drugs such as propofol and lorazepam. The Los Angeles County Coroner declared his death a homicide, and his personal physician pleaded not guilty to charges of involuntary manslaughter. Jackson's death triggered a global outpouring of grief, and as many as a billion people around the world may have watched his public memorial service on live television. In March 2010, Sony Music Entertainment signed a US$250 million deal with Jackson's estate to retain distribution rights to his recordings until 2017, and to release seven posthumous albums over the decade following his death.
