The report presents theoretical framework of relationships between terrorist organisations and media, and it describes them as an interactive modelling of a message. It introduces the concept of mediatisation of terrorism, and it offers a definition of this process. Moreover, the report develops it with six theoretical hypotheses related to: influence of media on selection of terrorists’ targets, adaptation of an act of terror to the ‘logic of media communication’, personalisation of terrorism and celebritisation of terrorists, creation of biased and oversimplified stereotypes, transformation of terrorist objectives into catch-phrases, as well as a role of political violence in agenda-setting of main news broadcasts. The presented concept will be verified in the ongoing comprehensive, quantitative-and-qualitative study on mediatisation of terrorism in American television, that will investigate the process between September 11, 2001 and the Boston Marathon Bombing in 2013. 

The most important issue of this paper is contained mostly, though vaguely, in the title. What is agenda-setting and how it is related with freedom of speech domain? In further part I will try to present those, theoretically distant problems. I will also try to present how political and business organizations can affect on daily agenda, so in fact how thy can create access to free speech. There are some situations in mass media world, when those practices can be considered as internal or external censorship. In this paper I specific cases, all selected from American political and media systems. I think that US system is full of contradictions, from law confl icts (state vs federal law, First Amendment), owners of mass media competition (corporations, FCC) and finally state controlled media on the contrary to free speech (censorship).
