The article is devoted to the consideration of the national features of the Russian political process in the context of deep mediatization, in which socio-political actors are embedded in digital infrastructures belonging to global Internet companies with their own political and legal subjectivity, as well as significant resources of influence. Understanding deep mediatization as a new stage of mediatization, during which digital media and the underlying infrastructures penetrate into all elements of public life, the authors study the current situation of global Internet companies in Russia as new subjects of political influence in the context of deep mediatization and identify problem issues associated with the regulation of their activities. With the help of content analysis, messages concerning the activities of global Internet companies were studied and problematic aspects of regulating their activities in Russia were identified. The comparative analysis revealed a shift in accents in the interaction of state authorities of the Russian Federation and global Internet companies in the context of deep mediatization and the current political situation. As a result of the study, the authors identify a number of interrelated trends describing the national features of the Russian political process in the context of deep mediatization, and also highlight the prospects for the evolution of the situation.
