Arbitron Inc. and comScore Media Metrix have released the online radio ratings for July 2005.

These measured online networks reached 6,756,100 million listeners according to the July comScore Arbitron Online Radio Ratings.

Yahoo Music, American Online's AOL Radio Network, Microsoft's MSN Radio and WindowsMedia.com, and Live365 (operating as the Ronning Lipset Radio Network (RLR)) had an estimated 6,012,700 million listeners age 12 and older.

Clear Channel Online Music and Radio had 848,600 listeners during an average week in July amongst people age 12 and older.

(Note: Cume audiences for the RLR Network and Clear Channel Online Music and Radio can not be added because doing so would count people who listen to more than one network twice. The cume estimates for all online listening eliminates this duplication.)

While persons 25-54 represent fifty-one percent of the total United States population, according to the July ratings, in online radio, this demo represents seventy-two percent of all listeners to these networks.

Skewing younger midday, while persons 18-49 represent fifty-five percent of the entire U.S. population, this demo represents eighty-five percent of all midday online listeners.

In addition, the RLR Network shows a 1.06 rating point in Women 25-34, the first time an Arbitron comScore rated online network has achieved a full rating point for a key demographic.

The July report of the comScore Arbitron Online Radio Ratings service rated America Online's AOL Radio Network; Yahoo! Music; Microsoft's MSN Radio and WindowsMedia.com; Clear Channel Online Music and Radio, and Live365 during an average broadcast week in the month of July.

Ratings for all services can be viewed below.
