Abstract: The article considers the socio-philosophical prerequisites of modern media ecology. It is shown that, since media ecology as a scientific discipline was created and substantiated within the framework of social and philosophical representations of the largest representative of the Toronto School of Communications - Marshall McLuhan, - its instruments still bear the stamp of the philosopher's basic views. Even though many modern researchers working within this discipline do not share the McLuhan concept and polemic with him on a number of key issues in the theory of communications, the very research prospect of media ecology has a direct impact on their work. The article analyzes the materials of current publications on media ecology for the existence of theoretical problems related to the conceptual justification of the discipline toolkit.Among the most significant philosophical preconditions of media ecology stand out: the concept of historicism, as an assumption of the existence of an objective sense of history and the possibility of its comprehension; the concept of social realism, as an assumption of the existence of social groups as independent entities; the concept of technological determinism, as the assumption that technology has a direct mechanistic effect on society; and the concept of unifying the effect of the media, as the assumption that the medium of communication affects the entire social space in the same way.
