This research analyses the media coverage of Social Security Reform in Brazilian telejournalism, specifically investigating if Jornal Nacional (JN) and Jornal da Record (JR) have pluralized and diversified voices when reporting about the Social Security Reform, considering that they are supposed to follow the journalistic principals as impartiality and objectivity according to the Code of Ethics of Brazilian Journalists. A bibliographic research was performed to understand the social function of Brazilian television through a brief historical route (BARBOSA, 2013). It is believed that it can resolve the intrinsic relations among this apparatus, the business model (BOLAÑO, 2004), the concentration of media outlets (BRITTOS, 2004; LIMA, 2011) and the function of telejournalism in our society. Alfredo Vizeu s (2000; 2009) and Beatriz Becker s (2005; 2016) concepts were considered in the analyses. In order to attend the objective of identifying the voices heard by JN and JR, a content analyses was performed in the way proposed by Bardin (2016), and after examining 36 editions focusing on the theme, it was possible to say that those TV News have given privilege to some voices instead of others. As a result, all the voices heard by both programs were for the reform. None of the TV News, in the analyzed editions, have shown different points of view, which did not allow a manifestation of opinions or a free debate of ideas.
