A tétrade de McLuhan na pesquisa em comunicação: revisão sistemática de aplicações no Brasil e em Portugal

This article presents the results of an exploratory work to map the application of McLuhan’s tetrad, in communication studies in Brazil and Portugal. The methodology used was the systematic review of the literature in the last decade (2009-2019). For such mapping, academic works (theses, dissertations, articles and chapters) were located from indexing systems, public repositories and specialized search engines. The goal was to discover how the tetrad has been applied and to which purposes. Finally, the potentialities of this tool, called McLuhan’s “exploratory probe”, are pointed out.
