It wasn't released because he didn't release his own pro footage / concert footage ?
It wasn't release because he didn't release it -- He probably had plans to for BAD 25 Anniversary tho
It wasn't released because Michael wasn't ready or didn't want it released yet.
But he had huge plans for the releasing books, games albums lots of memorabilia. Footage could have been released also . MJ had already signed contracts with Bravado through Branca for many thing before he passed. I believe a lot would be out even if he hadn't died . He was just getting started to bring much more to the table.
All this would be put into play during his TII concerts and other venues he was planning. it wasn't just because he died. Michael was still very popular and sought after in the entertainment Biz. He wasn't considered a has been or ignored as some who were not around want to say.
It was MJ himself that took himself out of the spotlight for a few years after the trial to recoup and raise his children. when he did decide to return the world responded and he sold out his London venues and broke the record. Even crashed ticket master LOL because they couldn't keep up with the demand. Its the media that puts a bad spin and negative spin on everything - MJ was loved and was shown the love by his fans and the industry just as he always was. We wanted him back they wanted him back and on top where he belonged.
Its well know that once a celebrity is gone. What's left of them become more sought after.
but I wouldn't use that to say all these things wouldn't have come into play while he was alive
We have plenty of evidence of "You ain't seen nothing yet " ... MJ was bringing it
