At a time when a growing number of authors write about declining standards and professional criteria of journalism, the paper "The role of journalists and editors in agenda-setting on the example of city section of Večernji list" wants to answer the question: "Who sets the agenda in a newsroom?". The goal of this paper is to determine who are the creators of the ideas for the articles and what is the role of journalists and editors in defining the topics, especially in relation to the other actors, such as public relations professionals, political actors, citizens, news agencies and the other media. The theory of agenda-setting has been chosen to answer the research question and to show whether the negative trends in journalism are visible through the example of setting the agenda. The author of this paper conducted empirical research which used a specific research method that combines testing the actors and content analysis in which the journalists themselves were involved. Although the main assumption was that journalists and editors are creators of ideas for the mayority of articles, it is disproved, and the results show that the idea for the articles in the city section of Večernji list has come from public relations in higher number of cases. However, with the assumption that the simplest comparison and setting the aspect ratios do not necessarily give a true picture of relationships and roles, other variables and characteristics of analyzed articles were also taken into the consideration. Thus, the results obtained clearly show that the articles in which the idea came from the journalists and the editors were larger, better positioned, more analytic, and had in higher number of cases better graphical equipment with at least one source of information. On the other hand, the articles in which the topic comes from the public relations were smaller, poorly positioned and in most cases didn’t have graphical equipment or didn’t mention the source. Given that this is the first study on this subject in Croatia, the results provide guidance for future research of agenda-setting and the relationship between journalism and public relations.
