UPDATE: From the AP:
Michael Jackson, the sensationally gifted "King of Pop" who emerged from childhood superstardom to become the entertainment world's most influential singer and dancer before his life and career deteriorated in a freakish series of scandals, died Thursday, a person with knowledge of the situation told The Associated Press. He was 50.
The person said Jackson died in a Los Angeles hospital. The person was not authorized to speak publicly and requested anonymity.
The circumstances of his death were not immediately clear. Jackson was not breathing when Los Angeles Fire Department paramedics responded to a call at his Los Angeles home about 12:30 p.m., Capt. Steve Ruda told the Los Angeles Times. The paramedics performed CPR and took him to UCLA Medical Center, Ruda told the newspaper.
Jackson's death brought a tragic end to a long, bizarre, sometimes farcical decline from his peak in the 1980s, when he was popular music's premier all-around performer, a uniter of black and white music who shattered the race barrier on MTV, dominated the charts and dazzled even more on stage.
His 1982 album "Thriller" - which included the blockbuster hits "Beat It," "Billie Jean" and "Thriller" - remains the biggest-selling album of all time, with more than 26 million copies.
