Media Imperialism is a critical theory regarding the perceived effects of globalization on the world's media. It is closely tied to the similar theory of cultural imperialism.
As multinational media conglomerates grow larger and more powerful many believe that it will become increasingly difficult for small, local media outlets to survive. A new type of imperialism will thus occur, making many nations subsidary to the media products of some of the most powerful countries or companies. Significant writers and thinkers in this area include Ben Bagdikian, Noam Chomsky, Edward Herman and Robert McChesney.
The United States corporate media coverage of events is seen to limit the freedom of the press. Integrity can be lost among media giants. This combined with the control and flow of information reduces the fairness and accuracy of news stories. American news networks like CNN also often have large international staffs, and produce specialized reigonal programming for many nations.
Media Imperialism is not always an international occurrence, however. When a single company or corporation controls all the media in a country, this too is a form of Media Imperialism. Nations such as Italy and Canada are often accused of possessing an Imperial media structure, based on the fact that much of their media is controlled by one corporation or owner.
By ignoring and/or censoring important social issues, the modern tabloid, twenty-four hour news channels and other mainstream media sources contribution to the freedom of information remains slim.
