The issuesof media concentration have currently been quite often the topic of public discussion and the subject of study of many analysts and publicists. The fact that the processes of concentration in recent decades are beginning to acquire a global character is first of all evidenced by the creation of large transnational media corporations, which are already showing a desire for international domination in a particular area of the media business. In addition, media owners from developed countries are actively expanding into the information markets of developing countries. Given the global impact of information technology on the entire socio-economic space, it seems necessary to define the concept of information globalization, to assess the scale of information shifts in the modern media economy. The relevance of this study is due to the need for a scientific understanding of concentration and diversification as forms of organizing media business in the context of globalization. Researchers identify globalization, convergence, glocalization, demassification, and diversification as the main trends characterizing the development of modern mass media.The purpose of this articleis to characterize the processes of globalization in the communication industry that have influenced changes in the structure of the media market to describe the models of diversification and mutual integration of holding media.The theoretical and methodological basis of the work was formed by conceptual provisions, recommendations, and conclusions presented in the fundamental scientific works of domestic researchers on history, theory, typology, research methods of the Russian media industry (E. L. Vartanova, S. M. Gurevich, E. Ch. Andrunas, S. I. Beglov, S. S. Smirnov). When writing this article, we used the methods of system analysis, as well as expert analytical, descriptive, historical and theoretical methods.Conclusions. Globalization of information space, as an inevitable and extremely important phenomenon, affects all spheres of the socio-economic life of society, changing the motivation of economic actors at the micro level and modifying the macroeconomics in general.
