Ada C. Machado da Silveira 64 a substance or a meta-structure, nor does it assume that media systems are autonomous. This is a way of thinking about the media as a constituent part of the orientation of reality and so- cial relations. For the first author, the concept of mediatization encompasses the idea of “a socio-cultural mutation centered on the current functioning of communication technologies” (Sodré, 2014, p. 109). Platformed interaction involves addressing platforms and their inherent algorithm and datafication requirements. The platform as a structural way of circulating news has an impact on journalistic language and the news is now considered a “narrative unit” that contains information about certain politi- cal, economic, social, cultural facts or events, etc. (Duarte, 2022). Therefore, what some have called the “platformization of journalism” emerges, which leads to problematizing the confron- tation between the visions of the exercise of political power, as I will address further on. I inquire about the journalistic attributes of news activities developed in societies with autocratic imprints.

It is a crisis of identity in journalistic ac- tivity provoked by the clash between the formality of canonical procedures stemming from the culture of print journalism and the disruption brought about by the innovative practices of digital journalism, practiced by digital natives and anchored in visual information. In full implementation, platform journalism promotes a redefinition of the information field, as well as the principles of legitimization in a numerical or datafied context. A reality inwhich datafied user feedback, in Poell’s expression (2017), highlights the relevance of data and consumption metrics. These aspects have become determining factors in defining journalistic content. This new reality leads to considerations about the ra- dial system that has been replaced by the emerging digital net- work system. The previous radial system assumed the exclusion of most Brazilians as its interpretative community, especially the community of readers, which was restricted, unlike the communi- ty of listeners (popularized) and television viewers (progressively incorporated into the spectrum of audiences). The hierarchizing capacity of the media has thus carried the structure of popular
