If you mean has it disappeared up its own arse and become a prime punching bag for the general public, then I would say. But only on occasion. It really depends how sad your sense of humour is. Fashion is a good example, advertising creates a bullshit, aroma, aura around a average products which are mass produced for amounts knowingly ridiculously higher than their real worth. I last saw this piece, or pieces at the Cuggenhiem Museum in New York.
Advertising gets the sizzle to sell the sausages even if the sausage is shit.
Can advertising sell anything - justify. I'm sure everyone circums in the end. Tony Kaye will be remembered as a genius. Whilst there are probably quite a few people in the UK with just as many talents, Tony is one that has worked at letting people know about his talents. Picasso and Dali were relentless self promoters.
