Note: Cume is defined as the number of different people who listen during a given daypart. Cume audience estimates for individual networks should not be added, because people who listen to more than one network will be counted twice. The reported audience for the total of the four networks is an unduplicated estimate of the number of different people who listened to one or more of the networks for a minimum of five minutes during the week.

*The Ronning Lipset Radio (RLR) Network is comprised of Yahoo Music, American Online’s AOL Radio Network, Live365 and Clear Channel Online Music.
