The current discussion on the teaching of literary theory in the context of new media is mainly carried out at the technical level, which has obviously missed the point, because the influence of new media on literature is by no means like that of a simple tool or carrier. Instead, it is directly related to the fundamental problem of literature. New media literature is such a brand-new literary style that the existing literary theories are unable to effectively explain it. The prejudice against and misunderstanding of new media literature reflect the deep crisis of literary theory. In order to recover the status of literature and art discipline as a "meta-discipline" relative to other literary disciplines, it is necessary to redefine literature based on the reality of current new media literature and to construct a historical and anti-essentialist literary theory.
