Michael Jackson estate has rolled in almost one billion dollars in the year since he died, according to media reports Tuesday.

That's 47 times what the debt-ridden King of Pop made in the previous year when he was still alive.

The huge sum was mainly from record sales and lucrative deals brokered by the estate.

It is two thirds of what Elvis Presley's estate has made in the 33 years since his death.

If the cash keeps coming in, the king's three children will all become billionaires when they reach 21, thanks to the trust funds.

A source said: "The estate has made around 900 million dollars in cash since Michael's death. This is an incredible amount. No other artist has ever made that much since they died. It should ensure Michael goes down in history as the greatest artist of all time."
