As the lecture is on Monday and the seminars Tuesday/Wednesday it is unlikely that you will have access to the reading (Winston, B. (1998), Media, Technology and Society: a history from the telegraph to the internet London: Routledge, pp321-336.). If you would like to read something else you could take a look at some of the articles in a special issue of the journal New Media and Society edited by Jankowski et al (2004) 'What’s Changed About New Media?' 6(1).
