Régis Debray is a well-known French philosopher and writer. From the late 1980s, Régis Debray began to study communication and media and tried to construct a new subject “media studies” in order to renew media concepts and broaden its research fields. He advocates the humanities of communication, focuses the interaction between technology and culture, and reflects common problems of cultural heritage and coexistence, which echoes Chicago School and Media Ecology. Introducing Debray’s thoughts would broaden the research horizon of communication in China and also be constructive for both subject depth and social development.
