The first-ever full year of online radio measurements is in, and it shows that the medium's audience nearly tripled during that time. Arbitron Inc. and comScore Media Metrix found average quarter-hour audiences increased 177% from October 2004 to October. The report covers the three original subscribers to the service: Yahoo!'s LaunchCast Radio, America Online's Radio@AOL Network and Microsoft's MSN Radio and Windows Media Network. Live365 joined the ratings in January 2005, and during the next 10 months experienced a 67% increase in its weekday individual listeners. Clear Channel's online radio station, which began in June, recorded a 14% rise in individual listeners.
