Yeah, only after he snuffed it though.
Not necessarily true.
When MJ died, most people bought "The Essential Michael Jackson" or HIStory as it had all his greatest hits and not just a selection. I would say Thriller was boosted though by the 25th anniversary re-release of the album in 2008 and the subsequent announcement he was going to perform at the 02 prior to his death so everyone would have already had Thriller who wanted it before his death really.
