Thesis approaches terrorism as a form of communication. An attack or other terrorist activities are ways of message coding. Its purpose is generally to spread fear among target public. For effective spreading of fear terrorists use media both indirectly, if a message is publicized in the news, or directly via new media mostly internet and its features, that enable cheap fabrication of widely accessible content. There is a symbiosis between media and terrorism. Terrorists create engaging events that are taken over by media which make an attractive part of their news coverage. Because of specific elements of reporting a distorted perception of reality is introduced. News coverage can never create a precise image of reality. There are many social and psychological phenomenons connected to the process of communication. It is usually terrorists who benefit from them, but some are working against their purposes. Thesis introduces an analysis of communicational strategy of militant Islamizes and concentrates mostly on global terrorism and Al-Qaida and its branches.
