Online Radio Broadcasters

Since 1998, Arbitron has been tracking consumer attitudes and use of online radio. Our annual studies generate publicity for the growing medium and have become the benchmark for the industry.

The comScore Arbitron Online Radio Ratings service, our latest entry into this industry, provides online radio broadcasters with audience estimates that are the closest yet to traditional broadcast ratings. The service provides subscribers and advertising agencies with Average Quarter-Hour and Cume audience estimates for standard dayparts and demographics. This is the first major online radio ratings service to measure people—not computers.

The ratings service is based on approximately a quarter of a million U.S. participants within the comScore global consumer panel. Using proprietary and patent-pending technology, comScore passively and continuously captures the online behavior of these panelists regardless of whether they are listening at home, work or school.
