This paper discusses the possible consequences of mass media fragmentation over the structure and the functioning of democracy. Media fragmentation and audience segmentation are not new but they greatly increased in the very last years because of the long ongoing tendency towards commercialization and mostly because of the development of new media and the internet in particular. This has determined what is usually defined “the crisis of traditional journalism” that has become the very frequent topic of most of the seminar on journalism today. The last part of the paper looks at the possible consequences of these changes over the structure of democracy beyond the well rooted techno-optimism: increasing social and political polarization, new forms of political socialization, more complex process of social and political negotiation, new forms of public scrutiny.
