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

Collectives, circulation of social discourses, and citizen mobilization: the case of #RosarioSangra 135 dia continue to officiate even in (hyper)mediatized societies, as the place where what we usually call current affairs, our social reality, is configured. At the same time, it is true that platforms, as performa- tive infrastructures (VAN DIJCK, 2016), expand the possibilities of association, collective organization, and political performance, as well as transform how socio-individual actors link with insti- tutions policies and media organizations.

In this way, from the point of view of its mediatization, the mobilization - each of the three marches studied, but espe- cially the first two - assumed several of the characteristics that Dayan and Katz (1995) gave to the type of phenomena that they define as a media event: • These marches are not part of the information rou- tine of the traditional media which covered them but, rather, they are interruptions to assumed routines; • They were televised and broadcast on several live platforms; • They took place outside the television studios and were not started by media companies; • They have been planned and announced in ad- vance; and • They are even coated with the halo of the ceremonial. On the other hand, returning to popular mobilization in the street, it remains to be said that, far from the success of the first two, the last march held on November 10, 2016, had much lower attendance, and went completely unnoticed by the tradi-
