This article analyzes the impact on public opinion of the strategies of communication carried out by the Legislative Chamber of Minas Gerais (ALMG) during the 1990's. We evaluate whether the public opinion on the state legislature has changed along of this thirteen years, following a steady process of institutional innovation. Comparing results for different points of time between 1993 and 2006, we reject the idea that ALMG's public image is substantially different from standard public evaluation of Brazilian political institutions. We find that the institutional change process is noticeable and has a positive response only for the small public attentive to ALMG's messages transmitted by radio and television.
