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.
Arbitron and comScore Media Metrix recently announced their collaboration on a new service that provides online radio with traditional broadcast ratings including Cume and Average Quarter Hour estimates for standard dayparts and demographics. Cume is the total number of different persons who tune to a radio station during the course of a daypart for at least five minutes. Average Quarter Hour is the average number of persons listening to a particular station for at least five minutes during a 15-minute period.
"Ad agencies need credible numbers to justify making online radio part of their media plans," said Eric Ronning, managing partner, Ronning Lipset Radio.
"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."
