Using GPS to entice drivers to make purchase

Autoblog sibling Adjab reveals that companies such as Dunkin' Donuts and Cold Stone Creamery are looking into advertising their products on GPS devices. Such ads would notify users where these shops are located in the same way gas stations appear on GPS maps as points of interest. Users would even be offered software showing the company's logo or alert them when approaching the store.
