Digital Radio Mondiale (DRM) standard is a terrestrial broadcasting solution of “one-to many” rather than the “one-to-one” online/IP solution. This means that one of the many advantages of (digital) radio is its anonymity or that of the radio listeners, which in some societies can be a matter of even life and death. In digital DRM, however, through its extra and rich multimedia offering, unique to digital and not available in analogue that can be displayed on the receiver screen, listeners can be encouraged to write, phone, text radio stations, vote on shows, give feedback, ask questions, suggest additions to programmes like playlists and even buy tickets for advertised events. This can give an indication of the popularity of a particular radio segment, presenter, topic. The figures will never be precise but a good enough indication. In short, digital radio cannot offer precise audience figures but can give good and real indications of audience size and interests. Using the more sophisticated “red button” solution in DRM, broadcasters can get even better audience behaviour indication. Digital DRM cannot match exactly online but it is superior to the analogue radio, noted for poor immediate feedback.
