The authors demonstrate why ideology, as a set of certain views, values, constants, concepts, images, and myths, can be considered a measure, that is, an indicator of the culture of mass communications. According to the authors, the reason is that mass communications carry a certain ideology, which is created by certain communicators and spreads in specific historical conditions for specific social groups and political elites. The article raises the question of why the system of mass communications as a set of education, propaganda, and mass culture, organizing the spiritual space of the Soviet person, failed to build a system of convincing evidence of socialist values in the new political, economic, and social conditions. And the "old" proofs turned into "false consciousness", because at some historical stage they moved away from real life and began to live their own inner, "false" life. Turning to the theory of mass communication, the authors actually answer the questions related to how the media should function in order to create a truthful and socially attractive image of the world. The article contains materials, useful in the fields of training of "Advertising and Public Relations" and "Journalism".
