Objective: In the last two decades, modern media have been one of the most elaborate elements in shaping the socio-political changes of societies. The role of these media in the changes in North Africa is the goal that this article seeks to understand and explain. It is hoped that with proper understanding of the problem, we will achieve a proper explanation of the impact of cyberspace on our country. Method: The method is a descriptive-analytical method utilizing library resources and postmodern methodology. This method is based on components such as »collapse of certainty«, "deconstruction", "attention to various types of power, identity and discourse" and "presentation pictorial of a fluid, networked, and lacking center of power" with the results of " Cyber Revolution ". Results: Communication networks in Egypt and Tunisia made people more familiar with the new forms of life and different government structures and new demands, and gradually changed the attitudes and ideals of the people, and eventually, changed in the expectations of government and rulers. This new situation undermined the potential of the opposing political forces that were suppressed over the course of decades and balanced the interests of the antigovernment forces. Conclusion: Communication networks, although not the cause of the revolution in northern Africa, but with the function of "postmodernism", in context full of different fears, with general awareness, organizing protests, expanding communication, and political mobilization, exposed the crisis of legitimacy and disfunctionality of authoritarian sovereignty. And globalization of protests will ultimately expedite the collapse of these systems.
