Community radio is a radio service offering a third model of radio broadcasting in addition to commercial and public broadcasting. Community stations serve geographic communities and communities of interest. They broadcast content that is popular and relevant to a local, specific audience but is often overlooked by commercial or mass-media broadcasters. Community radio stations are operated, owned, and influenced by the communities they serve. They are generally nonprofit and provide a mechanism for enabling individuals, groups, and communities to tell their own stories, to share experiences and, in a media-rich world, to become creators and contributors of media.
In many parts of the world, community radio acts as a vehicle for the community and voluntary sector, civil society, agencies, NGOs and citizens to work in partnership to further community development aims, in addition to broadcasting. There is legally defined community radio (as a distinct broadcasting sector) in many countries, such as France, Argentina, South Africa, Australia and Ireland. Much of the legislation has included phrases such as "social benefit", "social objectives" and "social gain" as part of the definition. Community radio has developed differently in different countries, and the term has somewhat different meanings in the United Kingdom, Ireland, the United States, Canada, and Australia, where freedom of speech laws and de facto realities differ.
Modern community radio stations serve their listeners by offering a variety of content that is not necessarily provided by the larger commercial radio stations. Community radio outlets may carry news and information programming geared toward the local area (particularly immigrant or minority groups who are poorly served by major media outlets). Specialized musical shows are also often a feature of many community radio stations. Community and pirate stations (in areas where they are tolerated) can be valuable assets for a region. Community radio stations typically avoid content found on commercial outlets such as Top 40 music, sports and "drive-time" personalities. A meme used by members of the movement is that community radio should be 10 percent radio and 90 percent community. This means that community radio stations should focus on getting the community talking and not solely on radio (which is a technological process); the social concerns of community radio are stressed over radio per se. There is also a distinction drawn in contrast to mainstream stations, which are viewed as pandering to commercial concerns or the personalities of presenters.
