Ozzy Osborne turned marketing into the essence of his art. All great phenomena of popular music, from Elvis Presley to the Beatles, had been, first and foremost, marketing phenomena (just like Coca Cola and Barbie before them); however, Ozzy turned that into an art of its own. With Ozzy the science of marketing becomes art; art and marketing become one. There were intellectuals who had proclaimed this theory in rebellious terms. Ozzy was, in many ways, the heir, no matter how perverted, of Andy Warhol's pop art and of the underground culture of the 1960s. He adopted some of the most blaspheme issues and turned them upside down to make them precisely what they had been designed to fight: a commodity.

I doubt he had such deep insights into waht he was doing.
