The aim of this study is to investigate and explain the role of social media (Instagram, Facebook, and Twitter) in football, using the communication of the Football Club Dinamo Zagreb as an example. The specific objectives of the research are to determine how much the posts on the official social media of GNK Dinamo were a source of information for fans and their attitude towards the activities of football players on social media. The study focuses on the development of sports and football, and based on literature on sports public relations, sports marketing, and sports journalism, it aims to describe the changes that social media have brought to the communication, work, and operations of sports clubs. A survey was conducted to investigate which sources Dinamo fans use to obtain news about the club's activities and their satisfaction with the content posted on the club's social media platforms. The hypothesis that most fans get their information through social media, particularly Instagram, was confirmed in the study. The results showed that the majority of fans are satisfied with Dinamo's social media and those who expressed dissatisfaction provided specific reasons.
