There are a lot of disputes regarding the real potential and influence of online activism onto offline world events. In line with that the aim of this paper is to establish the relationship between online activism and potential for social activism in the events that are manifesting in the real world. For that purpose we have conducted a survey of a nationally representative sample of Serbia (around 1200 respondents). Online activism is measured through both usage of the internet as the main source of information, as well as usage of Facebook used as a tool for political participation. On the other hand, real world social activism is measured through belonging to different citizens and political organizations, as well as participation in different kinds of social protests. The results of our research revealed an interconnectedness between the intensity of online activism and the potential for offline social activism.
