Electronic media bring new possibilities for human communication and lead to significant changes in its forms. The book deals with the language and construction of Internet texts, their increasing spontaneity and informality, the oscillation between the spoken and the written, between standard and non-standard language, between public and private, the switching and mixing of languages, genres and styles. It highlights hypertextuality, interactivity and multimodality (use of emoticons, images, videos) as essential features of Internet communication. The participants in this communication are characterized by the need for self-presentation, associated with creativity and playfulness, but also by the need for contact with other users. The authors analysed large datasets (from 2018-2021), paying particular attention to online film reviews, online written sports broadcasts, institutional communication on Twitter, the formation of politeness norms on the network, and public-affairs vlogs on YouTube.
