This research deals with a content analysis and involves the Joinville public radio. Facing the importance of journalistic information and the effectiveness of the instantaneity of the radio, the analysis was done in three radio stations in the city (107.5 FM, Udesc FM and Joinville Cultural FM), aiming to understand how the radio journalism works inside them and if there is internal journalistic production in the respective stations, just like there is inside a printed newspaper editorial office and the like. In order to understand, it was necessary to listen to the journalistic programs, during one week, from all the stations; visit them to know who is involved and what their production structure is; and talk to the coordinators of each one to know how the programs are made. Based on the concept of radio journalism, it is concluded, from the results, that there is almost no journalistic production inside the public radio in Joinville.
