This diploma thesis deals with the media representation of celebrities, as it is designed within the framework of the adopted American television format of the late-night talk show. In the first part of the thesis, attention is focused on problems of understanding of the phenomenon of celebrities by various authors, as well as on the development of the late-night talk show itself and its characteristic features. The theoretical starting point is the theory of representation (Hall), three levels of representation (Trampota) and social construction of reality (Berger, Luckmann). The method of critical discourse analysis is chosen for the research and the four principles for the analysis are described: commoditization, infotainment, personalization, congeniality. The practical part presents an analysis of the typical representation of celebrities due to the principles mentioned above in selected talk shows which were broadcast in English and Czech languages in 2015-2016, namely American The Tonight Show Starring Jimmy Fallon and Czech Jan Kraus Show. Keywords: Celebrity, Late-night Talk Show, Media Representation, Personalization, Congeniality, Infotainment, Commoditization
