The article raises the question about a four-part disciplinary status of media linguistics. The object of analysis in media linguistics is media text. The subject of the media linguistics is speech activity reflected in the media texts. The main method of analysis in media linguistics is praxeological which allows to select four scientific areas of media linguistics, the objectification of speech activity in each area gets the own consideration aspect. The first area is the grammar of media speech, which aims to identify patterns of linguistic tools selection. The second area is the stylistics of media text, which shows the impact of typical speech activity conditions in the linguistic structure of media text and set of actions for achieving the communicative goals in different contexts. The third - media linguistic discourse study - reveals what types of polycode tools express intertextual connections in a procedural unity. The fourth area - critical-evaluative - reveals manifestations of “language abuse” in the media, the norms of productive speech activities and assessment criteria of its effectiveness. Consequently, media linguistics, being of a fourfold discipline, uses the specified path of praxeology. Local methods are used for achieving the research objectives in each part of the media linguistics. In the grammar of media speech - methods of analysis of speech act as the components of texts, in media stylistics - method of stylistic analysis of media textual models - typical communicative actions, born of the aggregates of speech actions. In media linguistic discourse study - semantic-pragmatic method, showing communicative actions develop model procedures of speech activity in the media. In criticism of media speech - methods of cultural and speech analysis and critical linguistics. The four highlighted areas, the ongoing in the analysis of the interaction, gradually reveal different sides of effective speech activity in the media environment.
