When Monster Media recently installed four giant interactive displays at Los Angeles International Airport on behalf of JCDecaux North America, it was the first of its kind for the airport — and also the latest indication that digital out-of-home is breaking the sound barrier in the air travel space.

“We now have about 22 systems in U.S. airports, and an additional 15 to 20 will go in before the end of the year,” says John Payne, president of Monster. The company’s interactive campaigns in airports have included displays where Travelers Insurance umbrellas multiply and contract as people walk by, and where snow blows across giant bottles of Coors Lite in a similar fashion.
