Media Audit Moves Forward in Wake of CBS, Arbitron Announcement

The day after Arbitron announced that CBS Radio is implementing its PPM ratings device, the Media Audit - which is developing a rival, cell-phone based measurement system - announced that it is working on issues raised by a panel convened by Clear Channel to review electronic ratings measurement proposals, Radio Ink reports. Reacting to the CBS's decision to use the PPM, Jordan said, "We are undaunted by the CBS announcement, and look forward to working with the committee in its effort to bring the radio and advertising industries the best possible solution for media measurement."
