Radio is surely one of the greatest inventions of all time when it comes to mass media. Although many have predicted its extinction as a form of mass media, radio has proven that it is very popular regardless of all those forecasts. Radio is a specific media type and although many might say every media is specific, radio has countless possibilities for improvement and should never remain at a level it is currently on. The main goal of this final thesis is to present and compare similarities and differences of news broadcast by public and commercial radio stations in Croatia, and determine how much do the audiences of these stations trust the media. There were two different methods of research used in this study. One was an analysis of listening and comparing two different radio stations, and the other an analysis of the trust the audience has in the information they receive, both of these carried out through a survey. The survey method shows that listeners mostly believe in what they see on television but they prefer entertainment on the radio. The research has confirmed the initial expectations and the hypothesis. News and entertainment programs are the two main components of programs of every radio station. Both of these programs adjust their contents to the targeted audience and their desires. For that reason it is important to know the needs and desires of your audience and gain their trust. However, it is important to stress that every radio station also adjusts its program according to the model of functioning. A public service and a commercial radio station have different audiences and different goals. One should take that into consideration when examining the contents of any radio station.
