Burger King's 1-Cent Whopper Is a Taste of the Robo-Car Future

At first bite, it seems no more than a clever way to boost sales at the expense of a competitor. When a hungry customer walks into a McDonald's (or within 600 feet of one), they can use the Burger King app to order a Whopper for a penny. The app will then provide directions to the nearest BK, where the now famished customer can pick it up. The promotion, good until December 12, is called the Whopper Detour. Burger King's marketing chief told CNN Business that more than 50,000 people have cashed in on the deal, and the fast food giant's app jumped to first place in the iTunes App Store's Food and Drink category.
