The influence of text information, known as "telops," on the viewers of television programs is discussed. In recent television programs, textual information, i.e., captions and subtitles, is abundant. Production of a television program is facilitated by using telops, and therefore, the main reason for using this information is the producers' convenience. However, the effect on audiences cannot be disregarded when thinking about the influence of media on humans' lives. In this paper, channel theory and situation theory are introduced, and channel theory is expanded in order to represent the mental states and attitudes of an audience. Furthermore, the influence of telops is considered by using a scene of a quiz show as an example. Some assumptions are proposed based on the considerations, and experiments are carried out in order to verify the assumptions.
