This paper pays particular attention to a temporal reality that presented through the relationship between newspaper and broadcasting. It examines two cases of international broadcastings by The Japan Broadcasting Corporation in 1932: the 10th Olympic Game in Los Angeles and the League of Nation Council in Geneva. In doing so, it assesses the "social time" that should be distinguished from modern clock time. With drawing on Benedict Anderson's discussion of simultaneity, the author delivers a temporal reality of "social simultaneity" as a sort of social time, which emerges only through media communication and its materiality, in order to understand temporal features of the broadcasting in our modern society.
