This study addresses two aspects related to knowledge management systems. First, it introduces knowledge management systems for broadcasting stations to develop a specific model. Second, it introduces the team-based approach as a methodology for designing and developing knowledge management systems. Beginning with a discussion on the concept of knowledge management, this paper examines the characteristics, current situations and evolved paradigms of broadcasting stations. In addition, 6 web sites of broadcasting stations are analyzed. The team-based approach is also presented in some detail on how it can be applied to other organizations. Results of this study show a knowledge management system with five subsystems for broadcasting stations.
