Conclusions. The active development and large-scale spread of innovative means of communication based on the use of computer technologies significantly influence the strengthening of communication processes, activating changes directly in the language of communication. The development of information and communication technologies at the beginning of the 21st century. largely determines the direction of development of the modern language of communication and the transformational processes of speech culture. The spread of new media, which is directly related to innovative interactive information technologies controlled directly by users, along with changes in the forms and types of communication, led to transformational processes of speech culture. Under the influence of new media, the norms of speech culture are changing, which leads to a decrease in the quality of language culture. Modern media space, in contrast to traditional media of the 20th century – radio, television and print media – cannot be characterised as a model and standard of speech culture due to the presence in media texts of grammatical and spelling errors, elements of clericalism, outdated clichés, limited vocabulary and reluctance to use synonyms, the presence of street lexicon, barbarism, elements of colloquial language, activation spread of foreign vocabulary, illiterate construction of phrases, and incorrect use of words in a stable word combination. The language of new media is a unique organism that exists and develops according to its own rules. Non-compliance with the norms of speech culture, stylistics, violation of spelling rules, deliberate distortion of vocabulary, the use of foreign vocabulary, increased use of peculiar vulgar, and sometimes exaggerated mincing jargon are common in the Internet space. In this context, the promotion of the native language, the struggle for its purity and compliance with the rules, regardless of the field in which it is used, is of particular importance. Given the blurring of boundaries between real and virtual communication on the Internet, a high speech culture should become an example to follow.
 Key words: speech culture, new media, Internet, media space, mediatisation.
