The biggest changes that social networks brought are related to the communication and transmission of news to readers. It is precisely because of those changes in the news receiving process and its impact that the need to further explore the analysis of social networks’ content regarding the topic of terrorism that users post accompanied with the hashtag ‘#terrorism’ has been recognised. In order to complete the research, a survey was conducted to determine the perception and attitudes of social media users when it comes to terrorism on social media. The sample included respondents from the Zagreb area (n=100). The results of the survey revealed that social networks really do take on the greatest informational role in the matters of terrorism, that written articles are the prevailing form of content for information regarding terrorism, which can be associated with censorship that makes disturbing images and videos not available, and that the level of popularity of a particular social network is different in individual countries, and therefore the amount of available information differs accordingly. For further research, it is recommended to include other subjects into the sample, i.e. users of social networks from the Republic of Croatia and to determine whether the obtained results are realistic.
