The aim of the present research is to analyze the representations of individuals and spaces in the city of Rio de Janeiro mediated in RJTV 1st edition, a local newscast produced and broadcast by Rede Globo television network. We base our study on the premisse that, while narrating the cities, newscasts construct representations of city spaces and individuals, simultaneously creating images of themselves as enunciation devices. Our approach to the analysis procedure is based on the most journalistically relevant theme in the newscast editions present in our research corpus: the dengue fever. The theme redimensions day-to-day life in the city of Rio de Janeiro as mediated in RJTV, so that other themes that are always present, such as urban violence, lose journalistic importance. When an epidemic is identified, the newscast increasingly invites more social individuals to comment on the theme, be them public individuals, important inhabitants or common people from the city. Therefore, RJTV acts as an institution that produces and configures meaning on said individuals and on the spaces wherein they circulate or live.
