The purpose of this study is to develop an interactive prototype for interactive television content design. The development process of the prototype for interactive television broadcasting consists of two stages. At the first phase of the process, eight experts' opinions were asked who accepted to take part in the study and are experienced in interactive TV and content from Netherlands, the USA, Australia, Singapore and Turkey. Therefore, this study is structured as a qualitative case study. According to the data obtained from the research, it was concluded that the design principles for interactive television broadcasting and the interactive applications for these principles carried out with 4 themes. These themes; creating interactive content appropriate to the visual language and aesthetics of television, second screen application in interactive television broadcasting, supporting control elements in line with the individual differences of the participants and providing online applications. In the second process step, in accordance with the data gathered from these interviews were applied to an interactive football program design. As a result, the content design created for each program offers the user a different level of interactive environment. Whether the program is appropriate to the visual language and aesthetics of television affects the user's behavior, the quality and naturalness of the interaction presented. The higher the number of online parameters changed in interactive football design, the higher the level of user participation in the football program. The level of interactivity in the football program is related to the interaction of the participants by making meaning through the personal symbols transmitted and the involvement of the participant in the content at the point of reciprocity, responsiveness and responsiveness.
