If behavioral marketing is invasive, wait until there's DNA-based marketing, writes Haydn Shaughnessy at Forbes. Shaughnessy discusses a report from Social Media Today on a presentation on DNA marketing at South by Southwest in Austin from ad agency Yamamoto's Paul Saarinen and University of Minnesota geneticist Scott Fahrenkrug. "If a company could access your DNA and could find out you like bitter tastes or are lactose intolerant, they could market very specifically to your tastes," Social Media Today says. Saarinen and Fahrenkrug have started a company, called Miinome, that is opt-in and "would take your DNA information and sell it to corporations for use, but in return for money, or a piece of the action if a blockbuster drug is developed."
