The Concept of Media in the System Theory of Niklas Luhmann

This thesis deals with the concept of media by Niklas Luhmann which he developed as a key perspective for his theory of modern society. After the introduction, which is making clear the starting points of the system theory and the theory of society, follows a clear explanation - with a help of primary literature (especially Die Gesellschaft der Gesellschaft, Die Kunst der Gesellschaft, Die Realität der Massenmedien) - of Luhman's concept of media. The explanation goes from general distinction between media and the form to different types of media followed by massmedial communication. Selected contributions of contemporary theorists (Baecker, Esposito, Krämer) are integral part of the work. They give reflection and they further develop the topic of communication mediated by computer, which has been previously outlined by Luhman. In the end, the terms and the problems of computer communication are shown on current events on the Internet (Wikipedia, Facebook)
