Sport is the most widespread social phenomenon and is an integral part of most people's lives. Promoting a healthy lifestyle takes place mostly through sports activities so sport is of interest to the general public, and thus to the public relations profession. Insufficient or no sport activity can significantly affect the lack of quality and health in individuals' lives. Not just football is "the second most important secondary thing in the world" but almost all sports. Sport promotes the development of trade, tourism, the sports industry and increases employment opportunities. The purpose of this paper is to study and investigate and analyze the communication of the basketball club Cibona from Zagreb through social networks and their communication with the public.
