The article analyses a new compositional peculiarity of modern fiction – the introduction of a text fragment related by its lexical and graphic features to one of the genres of network communication (chat, blog, electronic mail, etc.) into the structure of the literary works. The dialogue between characters, who communicate on the Net, becomes one of the stable text-forming means, performing various artistic tasks, including formation of the plotline, creating the image (atmosphere) of the time period, character images, reflection of “language taste of the epoch”, and so on. The reproduction of the main linguistic peculiarities of electronic genres, in its turn, enlivens the literary discourse to a considerable degree; the pastiche of network communication becomes one of the expressive means; the cultural dominant of our time – orientation towards visual perception of information – manifests itself. The research has revealed methods and means of transferring graphic and lexical features of genres of informal network communication in the fictional text. The main ways of reflecting the peculiarities of electronic speech are direct stylization (reproduction of alphabetic and other graphemes used in Runet) and indirect image (verbal designation of non-alphabetic graphemes), which becomes the basis of a new imagery, the tropics (laughing brackets, emoji got nervous, an offended smiley, etc.). The analysis of the features of the display of speech behavior on the Net allows to conclude about the formation of a kind of poetics for the artistic embodiment of the stable theme of modern literature – ”Man in the virtual sphere of communication and being”. The study is built on the basis of general philological analysis and specifically linguistic analysis of a fictional text (total number of analyzed works is about 60) and presents a part of the author’s separate research on the formation of Russian Internet lexis in the modern Russian language and realized within the framework of functional sociolinguistics.
