摘要：The present decline of public service broadcasting is related to the transformation of the public sphere driven by the new galaxy of communication. The traditional argument of scarcity no longer applies in times of media and information abundance, and public service broadcasting loses its privileged place of the keeper of the public space. The transformation of the public sphere that is linked to the new media abundance is evidenced by the fragmentation and modularisation of publics served by different types of media. At the micro public level, the local and community media create virtual spaces of the public, at the mezzo level the national media facilitate mezzo publics, and the World Wide Web, faxes and the whole galaxy of communication enable the appearance of the macro publics at the global level. Even though the concept of public service media in its traditional sense is no longer viable, the concept of public spheres remains very important to democracy, as an original.
