How about scented ads? The WSJ, no less, is on the verge of offering "rub and sniff" advertising, according to Ad Age, which got it from Journal Publisher L. Gordon Crovitz. "You actually have to rub some part of the ad," he said, noting that chocolate and perfume scents have already been perfected. USA Today is preparing to test a similar, scented run-of-press ad product. Heck, whatever works.
