Purpose: In recent years, the problems of tabloidization of TV news programs and abuse of telops in TV news have grown. Telops in TV news were originally intended to improve understanding of the contents by introducing an information redundancy effect. This study examined by experiment the information redundancy effect of telops when watching TV news.

Methods: The experiment included two components: 1) tracking the eye movements of subjects when watching TV news, and 2) examining the degree to which the subjects understood the news contents. As subjects, 22 undergraduate and graduate students participated in the experiment. The participants were divided into two groups: a telop group who watched TV news with telops, and a no-telop group who watched the news without any telops. In the experiment, the differences of eye movements and understanding of the news contents were measured and analyzed.

Results: The results from eye movement tracking showed that eye movements in the telop group tended to react sensitively to the appearance of telops. Also, the analysis of understanding showed that the correct answer rates of the telop group were higher than those of the no-telop group for several of the questions. Thus, information redundancy affected the understanding of TV new contents in the experiment. However, telops induced some misunderstanding of some questions.
