When American Eagle opened its Times Square store in late 2009, most of the attention was on the retailer's sprawling 25,000-square-foot, four-story floor plan. But in the year and half since then, it's the brand's towering building-side LED display that's had the most noticeable impact, even in one of the world's most notoriously cluttered visual landscapes. By the numbers, this digital ziggurat is 15,000 square feet of LED, climbing 25 stories above Broadway and playing animations 18 hours a day. It's one of the nation's premium ad spaces, not only for American Eagle but for the brands and charities that buy (or are given) space there. We've compiled 10 of the more interesting ways the display has been used. Check them out after the jump.
