Modern advertising is specifically engineered to evoke an emotional response in order to buy a product. The mother/fathers of modern advertising are none other than Edward Bernays and Anna Freud. (Sigmund Freud's nephew and daughter). There's a lot of evidence that Freud resented both of these family members for using his psychoanalyst tools to help industry and government gain profit and power. At the same time, Edward was instrumental in promoting the English version of Freud's book, keeping Sigmund out of the poor house.

I highly recommend watching The Century of the Self. It's a multi-part BBC documentary that goes into the history of advertising and consumerism as we see it in our current age.
