"Since it emerged, the field of communication for development has undergone a constant process of redefinition. Since the 1990s, the importance of participation in social and communicative processes has been stressed, and studies carried out during those years focused on participation as an important component to be considered. The so-called community media are privileged forces driving the participatory communication for development approach. Since their emergence and up to the recent studies, community media have been characterised by the centrality of citizenship participation in the creation of widespread messages, and in the processes of social change that they promote."
