Internet radio audience measurement is any method used to determine the number of people listening to an Internet radio broadcast. This information is usually obtained from the broadcaster's audio streaming server. Icecast, Nicecast, and SHOUTcast are examples of audio streaming servers that can provide listener statistics for audience measurement.[1] These numbers often include information such as listeners' IP addresses, the media player they are using, how long they listened, and their computer's operating system.

This approach differs greatly from terrestrial radio audience measurement. Demographic and psychographic information cannot be easily collected due to geographically diverse nature of typical Internet radio audiences.[2][3] Arbitron, a research company in the United States which collects listener data on terrestrial radio audiences, has begun collecting listener data for Internet radio stations based on a panel of 200,000 users. The statistics collected from those users is then projected against the estimated 52 million actual Internet radio listeners.[4]

Another company named Triton Digital, a software company in the United States also measures worldwide Internet radio audience. It uses actual data collected from streaming servers rather than estimated data.[5]

TouchCast, along with numerous other online companies offer commercially downloadable stream analytics software called CasterStats, which allows any broadcaster to measure its internet audience from their streaming server data.[6]
