Theoretical apparatus of media studies and other interdisciplinary linguistic fields were employed for comparative analysis of genre characteristics. The paper is part of a longitudinal study of print media genres over the period of 2002-2010. The aim of the research is to(a) define and compare genre characteristics of the British, U.S. and Georgian print media,(b) examine and define structural and linguistic(semantic, pragmatic, semiotic) characteristics of the British, U.S. and Georgian quality newspaper genres,(c) define deictic composition of newspaper articles and(d) study expression of coded meanings in media texts. In this paper, I will focus on two major genres of quality print media: news and features. The media genres are analysed within the theoretical framework of pragmatics, semantics, semiotics and media studies.展开更多
