The purpose of this dissertation is to analyze the radio show Museu do Ipiranga, produced by Osvaldo Moles and broadcast by Rádio Bandeirantes, between 1951 and 1953, in São Paulo. In this sense, it seeks to identify the concepts of history and museum articulated, practiced,and disseminated in the program, as well as understand the teaching and dissemination methodologies. For this, I make a “dense description of the audios and scripts of the trailer and the debut program, also seeking to understand the communication that the producer attempted to establish with the listeners. In addition, I sought to understand the trajectory, the networks of sociability and the role of intellectual-mediator played by Osvaldo Moles as well as his interest in programs such as Museu do Ipiranga, since it is not a program of marketing appeal. The role of Sérgio Buarque de Holanda in the production of the program and his contribution, not only as a historian, but also as director of the Museu Paulista at the time, is also the object of study of this work. Finally, the projection, the repercussion and the reception of the program in other media, such as newspapers, and the ratings, were studied in order to evaluate the impact of the Museu do Ipiranga program.
