The Persuaders

"The Persuaders" explores how the cultures of marketing and advertising have come to influence not only what people buy, but also how they view themselves and the world around them. The 90-minute documentary draws on a range of experts and observers of the advertising/marketing world, to examine how, in the words of one on-camera commentator, "the principal of democracy yields to the practice of demography," as highly customized messages are delivered to a smaller segment of the market.
Full documentary at Frontline. Especially interesting the chaper on Emotional Branding.
