The comScore Arbitron Online Radio Ratings service rated the three charter subscribers – America Online’s AOL Radio Network; Yahoo!’s LAUNCHcast; and Microsoft’s MSN Radio and WindowsMedia.com – during an average broadcast week in the month of October. Subsequent reports will be released approximately 30 days after the end of each calendar month.
The new ratings report also estimates that 334,800 people age 12 and older listened during an Average Quarter Hour (AQH) to the online radio services of the three charter subscribers, Monday-Friday, 6AM-7PM during an average broadcast week in October.
“These results help us validate the size and value of online radio for advertisers on a level playing field with traditional radio,” said Andy Lipset, managing partner, Ronning Lipset Radio. “Online radio must use the same metrics used by terrestrial radio to be included in traditional media plans.
