The present article analyzes the possibilities of the commenting translation in rendering modern media texts in online media discourse. The paper, which deals with Russian national and cultural realia, focuses on the methods of their translation into German. It investigates original publicist articles in Russian and their translations into German presented on dekoder.org. Russian cultural realia have been grouped thematically into the following categories: onomastic realia, administrative and governmental realia as well as the association-based realia. This realia corpus helped to elicit the forms and foreground the peculiarities of commenting translation as a tool to ensure adequate communication through the means of modern information and communication technologies. It has been proved that commenting translation is a method of translation, which can often be used alongside with other methods (transcription, word-by-word translation, finding equivalents and functional alternatives, etc.). It has also been found out that a commentary can be added to a translated media text by means of a note in a pop-up window, an information article (so-called “gnose”) or a hyperlink to other publicist texts. Pop-up notes and information articles provide readers with additional information, while a hyperlink stimulates the reader to read them
