CNN effect: The CNN effect is a theory in political science and media studies that postulates that the development of the popular 24-hour international television news channel known as News Network and CNN, had a major impact on the conduct of states' foreign policy in the late Cold War period and that CNN and its subsequent industry competitors have had a similar impact in the post Cold War era.  While the free press has, in its role as the "Fourth Estate," always had an influence on policy-making in representative democracies, proponents of the CNN effect argue that the extent, depth, and speed of the new global media have created a new species of effects qualitatively different from those that preceded them.  The term's coinage reflects the pioneering role played by the network CNN in the field, whose "saturation coverage" of events like the Tiananmen Square protests of 1989, the fall of Communism in eastern Europe, the first Gulf War, and the Battle of Mogadishu was viewed as being strongly influential in bringing images and issues to the immediate forefront of American political consciousness and beyond.  Despite these origins, the term as used generally refers to a broad range of real time modern media, and is not exclusive to CNN or even 24-hour news cycle broadcast cable news.
