CNN effect

The CNN effect is a theory in political science and media studies which states that global television networks, in their modern ability to provide live, 24-hours news coverage from anywhere in the world, play a significant role in determining the actions policymakers take and the outcomes of events.

[2][3] Of particular importance is the global coverage of events, such as the Tiananmen Square protests of 1989, the fall of Communism in eastern Europe, the first Gulf War, and the Battle of Mogadishu; these demonstrate the ability of TV news to bring images and issues from far-flung places to the forefront of American political consciousness.

[4]By focusing instantaneous and ongoing media coverage on a particular conflict, international incident, or diplomatic initiative, the news cycle effectively demands political attention, as governing politicians attempt to demonstrate that they are "on top of" current issues.

[5] Deeper penetration and wider broadcast of statements and actions by public figures may increase transparency, but it can also complicate sensitive diplomatic relationships between states or force an official reaction from governments that would otherwise prefer to minimize political risk by remaining noncommittal.

The information revolution and spread of global mass media through the Internet and international 24-hour news thus accelerates the policy-making process, requiring a faster tempo of decision and action to forestall the appearance of a leadership vacuum.
