This presentation illustrates the the historical evolution of the media media strategy of the Muslim Brotherhood (MB) in Egypt. It then summarizes the results of a content analysis of the official English websites of the Muslim Brotherhood (MB) and its political arm, the Freedom and Justice Party (FJP), over the week leading up to the Egyptian constitutional referendum of 15th December 2012. We show to which degree different communication functions that are central to social movements and political parties were present on the websites. Furthermore we summarize an analyse of collective action frames employed in the provision of information on these sites.
