Social Media has become an integral part of society. Tools like Facebook and Twitter enable people around the world to communicate, interact and share their opinions within seconds, with the number of users growing constantly. At the same time, the EU has made it a priority to intensify the communication between citizens and public institutions to make them more accessible and transparent. This thesis therefore asks the question, does the Austrian public sector see Fa-cebook and Twitter as a means to accomplish these goals? To answer this ques-tion we first need to define and explain the most important terms in this regard being, public sector, communication and citizen/customer. This is followed by a description of Web 2.0, Social Media and its possible use for the public sector, as well as a description of the explored platforms, Facebook and Twitter. During the course of this work three Austrian public institutions are investigated namely, the Ministry of National Defence and Sport (BMLVS), the Federal Ministry of the inte-rior (BMI) and the Parliamentary Administration. This is being accomplished by analysing their existing Facebook and Twitter presences, as well as interviewing an expert from each institution. The comparison of the results then leads to the conclusion, which is that the public sector does see Facebook and Twitter as a means to communicate with citizens but information is shared in only one direc-tion.
