Joe Jackson, the 79-year-old patriarch of the musical clan, made a surprise showing on the red carpet at the Black Entertainment Television awards, which had transformed into a remembrance for the pioneering King of Pop.

During a live interview on CNN television, Jackson introduced an unidentified man who appeared to be a business partner, saying he wanted to make "a real good statement".

"Marshall and I have - we own a record company. Talking about Blu-ray technology. That's the next step," Jackson said.

The blogosphere was instantly buzzing with outrage.

Warren Ballentine, an African-American motivational speaker and radio show host, said that he was flooded with angry messages over Jackson's comments.

"Joe Jackson and his lack of sensitivity and respect disgusts me," said one posting on Jezebel, a blog geared toward women.

Another person wrote on Jezebel that Joe Jackson's behaviour was "almost too ghastly to consider: a man seems pursued pretty much to the grave by the demons his father planted in him, and even in death the (expletive) ghoul is still hustling his son's corpse".
