Clear Channel Outdoor Lets Advertisers Match Customer Lists with Outdoor Ad Viewers

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. The company is now letting advertisers upload their own customer data to its system to allow even richer analysis. Plenty of individual-level data here although it’s technically anonymous.
