As of the latest Arbitron Radio Today 2009 Report . . . (9-2009)
Only 48% of all FM stations are streaming
Only 32% of all AM stations are streaming
Classical stations are the most likely genre to stream their programming – 82% of classical stations are streaming online. Then, Contemporary Christian, CHR, Alternative and AAA formats are most likely to be streamed.
As a point of interest, only 52% of news/talk stations and 48% of talk/personality stations are streaming online. Those stations aren’t required to pay SoundExchange for performance music royalties, which keeps some broadcasters from streaming, so it’s surprising that they’re not streaming online.
