The purpose of the current research was to design a model for the development of media reputation of event-oriented sports organizations. The current research method is based on a qualitative approach to the foundational data method (Strauss and Corbin's systematic model), which was conducted in the field in terms of the fundamental purpose and in terms of data collection. The statistical population of this research includes three groups of university professors (who have conducted at least two researches in the field of media, sports media), public relations managers of sports organizations (with more than 5 years of experience) and managers of event-oriented sports organizations (with more than 5 years of management experience) who were selected by purposeful or theoretical sampling (19 people). The qualitative approach of grounded theory was used for data analysis for open, central and selective coding, and open coding was done by analyzing the interviews. The pattern of development of media reputation of event-oriented sports organizations is affected by causal conditions (management, personal, occupational and functional characteristics) and taking into account extractive strategies (educational, new media, media and financial content) ) which is affected by background conditions (infrastructure and organizational structure) and intervening conditions (economic, human resources), we can witness the emergence of sports and organizational consequences. It is hoped that the results of this research will lead to the development of targeted media activities in sports organizations and the status of sports media among citizens and audiences will be improved.
