Mediatization, polarization, and intolerance (between environments, media, and circulation)

Ada C. Machado da Silveira 172 the activity of the printed media when recognizing the visibility of the periphery; and (c) journalism as a disciplinarian in deal- ing with social relations. From an empirical perspective, many issues deserve attention, given the media’s centrality evoked in such processes. The task force organized to carry out military intervention and carry out civilian control of the city of Rio de Janeiro in 2018 sought to count, in several ways, precisely with the power of proliferation of a culture of surveillance to carry out the pur- poses of the said intervention in favor of public security. The disempowerment of institutional public security agents in a cri- sis unleashed locally strengthened the political-police-military agenda in news coverage, a purpose that had been fueled for a long time, as noted in the 25 years of weekly magazines studied. Alongside this process, a crisis in journalistic mediation shifted it to a satellite condition between different communication pro- cesses. The intended search for a collaborative relationship be- tween the reference media and the digital social media sought to reverse the proliferation of the surveillance culture in politi- cal gain in a wide proliferation in face of the violence and fear disseminated in the news. There, we have a set of forces that ultimately proved to favor the return of the military to the presi- dency of the Republic of Brazil in 2019. Understanding that, in the historical process of the last 25 years, the leap in the consumption of news from professional activity (institutional approach to mediatization) has been al- lowed to the strong performance in digital social media (socio- constructivist approach to mediatization), the polarization of Brazilian society for a conservative and authoritarian impact is one of the perceptible consequences. The analytics of mediati- zation and the news outlined here may allow us to understand that the communicational questioning of journalistic mediation brings together the political disempowerment of institutional public security agents. An analysis that focuses on the political disempower- ment of institutional public security agents, taken as strong col- laborators in strengthening the political-police-military agenda in the coverage of reference media and digital social media, re- quires specificities particular to the Brazilian communicational
