The process of mediatization of culture is actively taking place in modern society. Today, the media have a significant impact on the civic position, views and level of speech culture and communicative behavior of the population. The profession of a journalist is one of the most important and responsible professions. That is why a journalist has to convey a good speech: correct, appropriate, logical, expressive. Unfortunately, the speech of modern media workers is far from the standard. It is replete with speech, grammatical and stylistic errors and inaccuracies. The unintentional replication of such errors and unfortunate word usage can impoverish speech and lead to communicative risks. Observations show that modern media actively repeat words, constructions, and ways of speech interaction that are fashionable in colloquial speech and popular culture, which are often far from the norm from the perspective of the literary language. In mass media culture, especially in the blogosphere, speech aggression and detabooing of topics that were previously considered forbidden for public communication can be observed. Journalists are paying less attention to the form of thought expression, and therefore some lexemes in the media are abnormally expanding their compatibility and changing their semantics. The globalization of communication leads to excessive and inappropriate use of English loan words in the media. Due to changes in the value system of the Russian society, the mass media are increasingly quoting advertisements, popular foreign films and TV series. Journalists are less likely to turn to academic dictionaries and reference books, focusing on the speech of the population while selecting a speech variant. The mediatization of culture leads to the fact that native speakers have blurred ideas about good speech, rhetorical ideal, traditional values, and the level of linguistic reflection decreases.
