This paper explores the new environment generated by the convergence-television-internet social networks. To this end, we look to characterize the “environment” in concept proposed by Marshall McLuhan. Second, we seek a characterization of the first social networking as a means hot and cold, with the conclusion that each social network generates its own environment and that, according to the contents thereof, can be cold or hot. Finally, we propose a set of lines of work to follow the purpose of exploring the contribution oh McLuhan around the environments, over all the electronic age, since it is an important path to follow to generate new knowledge about the mentioned socio-cultural environments and their impact.
