Scent Selling

Business 2.0: It’s not enough to have your customers’ eyes and ears–now you need to attract their noses too. This month, 100 gas stations in California will be trying technology that wafts coffee aroma at the pump in a bid to tempt its pay-and-go customers into the store for java.
Clear Channel, meanwhile, is experimenting with scented billboards. USA Today and the Wall Street Journal are set to offer “rub and sniff” newspaper ads. And some retailers are also preparing products with added smell. Wal-Mart is rolling out experimental DVDs with “smell-o-vision,” electronic scent wafers that release the odor of a burning building, say, or a freshly fired gun, at precisely timed moments during the movie.
