The CNN effect: The search for a communication theory of international relations

This study investigates the decade long effort to construct and validate a communications theory of international relations that asserts that global television networks, such as CNN and BBC World, have become a decisive actor in determining policies and outcomes of significant events. It systematically and critically analyzes major works published on this theory, known also as the CNN effect, both in professional and academic outlets. These publications include theoretical and comparative works, specific case studies, and even new paradigms. The study reveals an ongoing debate on the validity of this theory and concludes that studies have yet to present sufficient evidence validating the CNN effect, that many works have exaggerated this effect, and that the focus on this theory has deflected attention from other ways global television affects mass communication, journalism, and international relations. The article also proposes a new agenda for research on the various effects of global television networks.
