Abstract
This study aims to clarify the characteristics of the "Oral History Collection" by the History of Content Industry Archives Research Center (HARC) at ZEN University through a comparative analysis with the prior initiative conducted by the Institute of Innovation Research at Hitotsubashi University and the Ritsumeikan Center for Game Studies. Based on quantitative text analysis (co-occurrence network analysis) focusing solely on the interviewers' utterances, the results revealed that HARC, led by media experts, exhibited a "hierarchical question structure" that deeply explores specific themes. In contrast, the prior academia-led initiative demonstrated a "chronological question structure" connecting individual career paths with historical backgrounds. Furthermore, a comparison regarding public media (text/video) highlights the respective characteristics: video preserving live presence and embodiment, and text offering accuracy and searchability. By organizing these distinct features, this paper presents the multifaceted potential of oral history in the history of the content industry.
