^I have to disagree here... Good marketing doesn't make good sales alone (most of what people call marketing isn't even marketing
), the best promotion can't sell something nobody wants/needs... But people not always wants quality, and quality is a pretty relative term.
What most of those products have in common, including peak Ayu, is that they identified a market share that wasn't being explored and focused on it (
this is marketing
), Transformers and Twilight are very good examples because they really fits the "needs" of teenagers boys and girls of all age on this era. McDonalds pretty much created the concept of "fast food" with a bigger concern to hygiene than street foods and almost industrial production, what means you know what u r going to eat, it doesn't matter where u buy it.
What Ayu does right now doesn't match what teenagers "need" today as much as it did back in 2000... This makes here less "sellable" than she was...
