This paper addresses a neglected aspect of replay as media discourse, focusing on the judgmental debate among the perceptual experiences it provides. This paper revisists Harry Collins’ (2010) conception of “ubiquitous expertise” as the epistemology of sports judgment. Collins argues that because of the widespread use of video replays, sports judgment is no longer exclusive to a select group of experts, but has instead become common and widely practiced in front of a TV. While Collins’s argument is persuasive to some extent, its flaw lies in its exclusive consideration of replay as a visual technology. This paper examines replay as a type of media discourse that involves the interplay of video replay footage and sportscasters’ commentary. The ethnomethodological analysis focuses on the specific use of replay in sports broadcasts, clarifying the structure of the “instruction for seeing” (Goodwin 1996). The results demonstrate a departure from Collins’ argument. Collins presumes that the viewers must possess a profound understanding of the rules and regulations of the sport in order to make their own judgments. On the contrary, this paper demonstrates that such assumptions may be unnecessary and that the media discourse may guide the viewers to be able to make their own judgment. According to this paper’s findings, the mundane competence of understanding media discourses is more essential and fundamental for “ubiquitous expertise” than knowledge of the sport’s rules.
