At the time of his death last June, Michael Jackson was reportedly deeply in debt and had agreed to sign on for an unprecedented 50-date run at the O2 arena in London, as a means of turning his financial fortunes around.

But thanks to a flurry of merchandising deals and a flood of nostalgia-fueled 음악 sales, his estate has generated nearly $1 billion in the past year,Billboard reports via Reuters.

Billboard broke down the 출처 of that windfall, determining that nearly half of it came from the robust 음악 sales following the singer's shock death on June 25, 2009. Jackson has sold 9 million albums in the U.S. and 24 million around the globe since his death, along with around 800,000 copies of albums 의해 the Jackson 5 and the Jacksons. Assuming a worldwide retail sales price of $11.62 per unit, the magazine estimated that the Jackson catalog brought in about $383 million in sales.

It earned an additional $188 million overseas, while the DVD of the film raked in $43 million in the U.S., as well as $24 million in rental income. It earned $18 million just in 일본 on the first 일 of release and another $7 million in Blu-Ray sales.

Billboard also speculated that the sales of the TV rights to "This Is It" to Viacom (the parent company of MTV) may have generated an additional $15 million, and licensing fees for nontheatrical performances (airplanes, cruise ships, hotels) could bring in around $24 million.

One of Jackson's traditional cash cows, his 음악 publishing rights, was another lucrative 출처 of income, taking in nearly $130 million. The singer's Mijac publishing company — with an estimated value of $75 million in 2005 — has a current value of around $150 million, generating around $25 million a 년 in revenue, with that number possibly doubling to $50 million in the past year. Jackson's half ownership of the lucrative Sony/ATV catalog could be worth as much as an additional $80 million a year.

The executors of Jackson's estate have cut a series of deals over the past year, resulting in around $35 million in additional revenue. Because many 팬 declined to return their tickets to the 런던 This Is It shows, preferring to retain them as keepsakes, those tickets were worth $6.5 million, along with around $5 million in 음악회, 콘서트 merchandise sales; a 초 deal with merchandise maker Bravado cut in August reportedly included a $10 million advance.
