Cambridge University Press, ISBN 0521796687 One of the risks of continued access to the global dimension is to identify with an ethereal extraterritorial dimension, which is beyond the area in which you live, referring exclusively to the desired ones or who have visited, but disconnecting from what's going around in your body. In this sense, the local media are important, but necessary are those of a community type, ie that are able to implement the grammar media in the area, being able to express from the bottom needs, wishes, dreams and distortions of the social systems of Western, still a long way from self, despite the overflowing proliferation of communication media. As this text that explores in detail some significant U.S. cases, the freedom of action in small contexts has often produced ideas that have managed to brilliantly combine political activism and technological innovation. Here the 'reinforcement' that the media give the abuses, legittimandoli with aseptic comments drum swing, is dismantled with the same language from time to time TV (DCTV, railway nonprofit Manhattan), radio (WFHB, railway Community Bloomington, USA), printed (Street Feet, a periodical of the homeless in Halifax, Canada), and network (Vicnet, a portal for information and access to the network at low cost to the community of the state of Victoria – Australia). The use of the media that comes from deep social needs goes beyond its own borders of media traditionally understood, opening gaps in the collective consciousness for the support of local immigrant communities, as well as the relationship between the reality of the neighborhood and similar ones immersed in conflicts across the earth. A 'power' only, that the mass media have the almost deleted.
