Walmart installed mini LCD screens in the laundry aisles of more than 3,000 of its stores last month. The three-inch screens air 60-second commercials for Purex Complete Crystals when shoppers press a button located near the screen. Walmart is then able to track the number of shoppers who press the button and compare it to sales results.
