The purpose of this research was to investigate the role of media power sources in the development of sports in the country. The implementation method of this research was of a mixed type, which was carried out in two qualitative and quantitative stages. First, the initial model was identified with the foundation data method and the Strauss and Corbin approach, and then its fit was evaluated with the structural equation modeling method. Open, central and selective coding method was used for qualitative data analysis and PLS software was used for quantitative data analysis. The sample examined in the qualitative section included 15 experts in the field of sports and media, who were selected in a purposeful way. In the quantitative part, 276 people from graduate students of sports and media management were randomly selected and surveyed with a questionnaire. The findings of this research in the qualitative part include the power of learning, the power of persuasion, the specialization of the media and legal support as causal conditions and the ability to create flow, demand, generate income, build trust, authority, legitimacy, transparency and the type of media ownership as the underlying factors of identification and interfering factors to Two categories of facilitators and obstacles of media power in sports development were divided. By examining the effects of media power in sports media, sports and sports economics, practical strategies were presented in the fields of sports and media. In the quantitative evaluation of the model, all path coefficients were significant and the model was confirmed. Considering that the data fit criterion was equal to 0.098, the fit of the final model was confirmed. Based on the present model, the process of the power of the media on the development of sports can be analyzed and a new category can be reached, which is based on the opinions of sports and media experts.
