In the early years of radio it was the source of community news, weather, and information. In fact, the government authorized regional and national (clear channel) stations to serve those peoples who did not have access to a local station.
Community Radio Stations were mainly started to provide a mode of communication, information and entertainment for the local people or people belonging to a particular area.
Community radio stations are usually non-commercial, too, so they are underwritten by local organizations, providing an outlet for those organizations to spread their message. Call to action, promotions and other radio fluff are rare on these types of stations, marking a much more even listening experience.
