Current international communication is typified by flow of information from the northern to the southern hemisphere, dominated by the developed nations in information gathering and dissemination, and intensified by technological advances. The imbalance of communication flow, considered by developing nations as responsible for political, economic, and social problems, has precipitated rigid control of communication in many such countries. Communication can be used to promote world understanding and cooperation, to fuse and cross-fertilize, and to accelerate modernization and industrialization. But communication can raise expectations without always being able to provide immediate gratification. Inevitably, the unfulfilled aspirations for a better life or a better political or social system cause widespread social frustration. Third World nations, therefore, are inclined to reject Western communication models and systems without considering how to modify them to suit their own needs. A balance can be achieved not by excluding alien communication or by rigidly controlling the media through government censorship or ownership, but by judiciously applying the communication immunization theory, in which saturation elicits less and less response.
