Rhapsody says it’s reached a million subscribers for its digital music service, partly by acquiring its competitor, the paid version of Napster that Best Buy had owned. I seem to remember Rhapsody having a million back in the day, but that included a radio service like Pandora’s premium version. Meanwhile in the radio space, Arbitron, the Nielsen ratings of radio, reminded the world that it doesn’t count Pandora yet. (That’s because Pandora had commissioned its own study.) I dunno, if I were Arbitron, I wouldn’t admit I wasn’t covering the whole market, but that’s just me. Radio must be feeling some pressure from digital services. The big radio station holding company, Clear Channel, that streams radio via its I Heart Radio brand, reined in its ad selling unit that had previously been selling some Pandora inventory. The disruptions continue. Check out my RoadMap preso before my forecast gets posted to the site next month.
