Scientific video blogs (vlogs) are quickly developing online platforms for sharing scientific information as video content and covering a wide range of scientific topics for disseminating scientific information to a broad auditorium. In this paper the communicative and pragmatic parameters of a scientific video blog as an internet discourse genre are studied; the characteristics and features of scientific video blogs as well as their contribution to online communication are analysed. One of the key features of scientific video blogs discussed in the paper is the use of visual presentations for sharing complex scientific concepts through images, graphs, animations, demonstrations, etc. in a visually attractive manner, which increases the overall understanding and engagement of the audience. The linguistic parameters of vloggers’ verbal delivery play an important role in delivering scientific information effectively. They should use clear and persuasive language, avoiding jargon and difficult technical terms that may hinder comprehension and provide conversational and informal language style, making the content more accessible to viewers of various backgrounds. The interactive approach creates a sense of community and permits to exchange the ideas and knowledge. Scientific video blogs aim to bridge the gap between scientific research and the general public, making complex concepts more understandable and relatable for the diverse target audience, for which vloggers should tailor their content, using relatable examples, analogies, and storytelling techniques to enhance comprehension. Scientific video blogs have appeared as a popular genre of internet discourse, offering a unique and engaging platform for the dissemination and popularization of scientific knowledge. By creating visual presentations, using clear verbal delivery, and interactive elements, vloggers effectively communicate complex scientific concepts to a diverse audience. The communicative and pragmatic parameters of purpose, target audience, and credibility further contribute to the success and impact of scientific video blogs and are the subjects of further linguistic research.
