New and growing, Shopper Marketing is one of the hottest trends in marketing today. It targets consumers while they are in the store and involves every aspect of the shopping experience, from promotions, displays and packaging to the store layout itself. According to a study by Deloitte, spending on shopper marketing has doubled since 2004. Procter & Gamble alone invests at least 500 million dollars a year in shopper marketing. Microsoft, IBM, Coca-Cola and Nestle all have their own shopper marketing units.
