The article explores how emotionality is manifested in the news texts covering politically sensitive topics, using as the case study coverage of the 75th anniversary of WWII Victory in news programmes of the Russian TV “Channel One”, “Russia TV” and RT. Proceeding from the key theoretical assumption of medialinguistics defining media texts as an integral unity of verbal and media components, the author singles out and analyzes markers of emotionality at both - language and media levels, paying special attention to lexis and the way it is supplemented by illustrations and video footing. The analysis of the news flow is based on the information model, which allows to structure the process of news formation according to the following stages - selection of events for news coverage, interpretation of facts, shaping images, forming stereotypes and cultural-ideological context. The goal of the study was to identify markers of emotionality and analyze how emotionality affects the interpretation and the perception of facts, paying special attention to realization of the category of broadcasting style defined as the tone of voice, or tonality news media use when addressing their audience. Conceiving emotionality as both explicitly manifested and implicitly present quality, the study singles out its three types as represented in the analyzed media texts - 1) specific pretentious style, used by newsreaders and commentators to stress the dignity and solemnity of the event; 2) deliberate affectation disguised as emotionality on the part of news anchors while presenting topically sensitive news items; 3) emotionality as spontaneous display of sincere emotions observed in interviews, dispatches of correspondents and commentaries of the participants of the events. The results of the study could serve as a basis for further analysis of emotionality markers in different types of media discourse, including news, commentary and debate on politically sensitive issues in traditional media and social networks.
