In the 1960's many referred to OOH as the original broadcast media. Achieving eyeballs for brand advertising in sporting stadia and major travel hubs. Of course, it wasn't broadcast, but they were still selling an audience and packaged it as such. OOH has evolved dramatically. Combining Radio with its geo-targeting and OOH that can compliment it is smart. Why compete when you can work together under the same roof and provide a solution. More interesting sell for the great talent they employ as well. Interesting times.
