Jackson estate has generated $1 billion since death June 21, 2010, 6:22 PM EST WENN Michael Jackson's estate has generated almost $1 billion in revenue since the pop superstar's shock death last year, according to reports. The Thriller hitmaker has sold 33 million albums around the globe, in addition to 800,000 copies of albums by the Jackson 5 and the Jacksons since his fatal cardiac arrest, reports Reuters. Billboard magazine estimates music sales have already brought in $429 million in sales, assuming a worldwide retail price of $11.62 per unit. The report also included revenue from international track downloads, global ringtone sales and digital performance royalties. The revenue report claims a staggering $392 million has been garnered from TV and movie projects, including the "Michael Jackson's This Is It" documentary about the singer's final rehearsals for his doomed residency at the O2 arena in London last year -- which he reportedly agreed to sign on for as a means to rid him of his huge debts.

Meanwhile, Jackson's highly profitable half-ownership of the Sony/ATV music catalogue and other music publishing deals have earned the estate a reported $130 million.

The Jackson estate is guaranteed to earn between $200 and $250 million after signing a deal with Sony Music Entertainment bosses to release 10 Jackson albums between 2010 and 2017. The projects will consist of a collection of reissues and previously unreleased Jackson songs.
