Media corporations of a Western model have two overriding goals: as social institutions the mass media are expected to create a space for public discourse and transparency through critical observation of society. Besides this they are to act as a socializing agent and ensure quality content (for example, by concentrating on values like rationality, freedom, and accountability).As a free-market enterprise, certain specifications and goals are to be met in terms of broad coverage, reach and advertising revenue.The pursuit of these two goals creates great tensions in editorial departments, because the pursuit of one goal often obstructs the attainment of the other.
