Public relations are increasingly becoming one of the most important factors in sports. With the development of social networks, faster circulation of news around the world, sports communities and athletes themselves are even more exposed to sports viewers/followers. Of course, the aforementioned global change has its advantages and disadvantages. This graduate thesis focuses on the presentation and utilization of social networks and other media for the purpose of promoting the success of lesser-known sports and athletes within the countries of Croatia and France. The scientific methods used in the preparation of the paper are content analysis, comparative analysis, case study and literature analysis. Furthermore, by analyzing the content, i.e. posts on Facebook, Instagram, the official websites of the federations and internet portals, the thesis tries to show the diversity of approaches in the communication activity of the two judo federations, which is the very goal of the research. A detailed analysis shows the quality of the posts, the popularity of the post itself (so-called `likes' and comments) and the work invested in creating it. The results of the research and analysis were processed according to the set common parameters (frequency of publications, media effect, etc.). The work is reduced to ascertaining the differences in approach and creating recommendations for the continuation of the work and its improvement (short-term, mediumterm and long-term plan).
