In contemporary democracies, the establishment of a public space which is more open and accessible to disadvantaged groups, popular movements and communities is a major challenge. The media are both part of the problem and the solution. On the one hand, they strengthen or even produce divisions and the fragmentation of the public space. On the other, their use by social movements and civil society can establish connections between different social groups, include marginalized populations and regain the public nature of certain issues. Similarly, even if the use of digital resources overcomes obstacles that complicate participation in public debate, all the asymmetries do not disappear with the use of Internet, for instance.
