Abstract
This article brings a synthesis of the recent literature about the role the media have played in the transformation of the public sphere. Departing from this literature, a general research framework for a critical political economy of the public sphere is presented. The central thesis of this approach is that a political economy of the public sphere should not be restricted to an analysis of its institutional configuration and the actual labour process, but must extend its radius of action from the production of media messages to a political economy of reception and its signification.
