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

Ada C. Machado da Silveira 170 a socially constructed character. Deeply shaken by the partici- patory revolution implemented by digital social media, which overturned the legitimacy of established news production can- ons, organizations reiterated the skills of professional journal- ism in face of improvised fake news agencies. Seeking to historicize the process, I consider that it is possible to conceive that the institutionalist perspective of me- diatization in the news agenda is clearly perceptible until the increase in consumption power in Brazil. However, this moment saw the progressive autonomy of news content production ac- tivities by non-professional media agents who began to com- pete with professionals in the dispute for consumers. The new agents, active both in the production and in the proliferation of news content, can be understood as protagonists of the social construction in mediatization.

The reference media, threatened in its autonomy and pervasiveness by the proliferation of social media, considered that the phenom- enon of false news would be the marker of such a process. The interweaving that marks the experiences of what we call “peripheral journalism” establishes a practice installed in a being between ambivalence and liminality. Its ambivalence is explained when trying to construct discursively what is social- ly recognized in a previous way as a representation of identity. The liminality of the so-called peripheral journalism, on the oth- er hand, addresses the passage made in the face of the scarcity of resources that such proposals have.

Thus, we asked to what extent it is possible within the
