Sure, promoting hashtags within the boundaries of an event can get guests interacting. But put them outside the event's official walls and you're more likely to capture a bigger crowd. At the Cannes Lions International Festival of Creativity, a 3-D projection of tweets using the official event hashtag appeared on a 35- by 65-foot billboard. The digital activation, created by Incredible Machines, ran at night, while during the day the billboard showed a static image of the hashtag printed on canvas. Similarly, AOL placed its hashtag on a giant billboard outside the venue of its upfront event during Advertising Week in New York.
