For the purposes of the final paper, a survey was conducted in which 215 Croatian citizens participated in order to examine their perception and attitudes towards trust in the media and the ethics of the Croatian Internet portals. It has been hypothesized that more than 50% of respondents do not trust the media. The hypothesis was confirmed and the conducted research showed that the surveyed citizens of Croatia do not have a large amount of trust in Croatian internet portals and believe that the portals do not operate ethically. The results of the research showed that the surveyed citizens of Croatia rate their trust with a score of 2 out of 3. Respondents believe that the Croatian Internet portals do not operate ethically and they do not have a positive perception of the portals. With the help of scientific literature, the paper explained the determinants of ethics, ethical principles and controversies, fake news and misinformation. The analysis of the results showed that the respondents were familiar with the concept of fake news and that they were moderately concerned about the increase in misinformation and fake news. In order to be able to draw some concrete conclusions, it is necessary to conduct a survey on a significantly larger number of respondents and determine the real trust of Croatian citizens in the media and the ethics of the portals.
