Аннотация:Abstract: The article traces the evolution of the relationship between public and private during the development of human communication, starting from the earliest stages, when communication of a public nature was nothing more than a purposeful translation of general norms of behavior, taboos, beliefs, worldviews, attitudes toward power, helped to coordinate the efforts of the members of a clan, a tribe, in order to survive, to preserve some stability, to exist in time and space. Practically, such a model with some variations prevailed over a long period of human development. The new time has generated a new communication actor - a person who claimed to own a share of the private zone. In this sense, the practice of using social networks is interesting, with all their features within the stated theme: accessibility for supervising bodies and advertising are the defense of personal data, the possibility for communication in forums.
