Clear Channel Outdoor has more than 450,000 outdoor displays worldwide. At least some of those track nearby mobile devices, which lets the company profile ad audiences, measure campaign impact, and cross-target ads.

Oddly enough, marketers rate selecting marketing technologies as the thing they do best.
