Abstract
In this study I made a proposal that it is important for TV program analysis to be focused on the structure of them. For the structural analysis, it is need to consider a TV program as a system which is constructed from each scenes. Then I analyzed the NHK science programs focusing on their structure for case study. As a result of analysis, "tree-structure" and "network-structure" were founded in them. Through interview of the producers who have made TV programs, it is suggested that each structure is related to the program's aim. Further more I conducted a trial survey to the several university students in order to acquire the feature of "network-structure", for this structure has not clarified enough its merit or effect. The subjects were several university students. As a result of the research, it is suggested that "network-structure" brings out the various respond and a lot of questions from the viewers.
