Аннотация:Multimedia conglomerates of media corporations significantly expand the political and technological boundaries of the digitalization of modern political protest. These structures provide service, publishing, network, interactive tools for its complete digital visualization and electronic broadcasting. As a result, the very nature of political protest is being transformed. The mechanisms for organizing and conducting protest actions are changing, in some cases, the factors of their occurrence. The well-established components of political protest, such as direct nature, ultimatum, expressiveness, the orientation of the protesters' demands on other groups, the presence of an object for criticism, also become conditional and may not be present in the digital practices of protest political participation. Political events of the last two decades, such as the Arab Spring (2010), Euromaidan in Ukraine (2013), protests in Iran (2009), rallies in Russia (2010-2011, winter 2021), unrest in Turkey (2013), protests in Hong Kong (2019). and Belarus (2020-2021) show the ever-growing communicative possibilities of digital mechanisms of political protest in the absence of a number of its “classical” components and the introduction of its new components into political practices. Our article is aimed at identifying the causes, mechanisms, key trends in the digitalization of political protest in the context of the formation of new media corporations.
