In Sweden, as in many other european countries, alternative media with immigration-critical profiles have managed to establish themselves as new players in the media landscape in a way that challenges mainstream media (MSM) because their message is that MSM, seen as an integrated part of the political system, conceal or distort information that does not fit the “politically correct” agenda and/or that media discourse is constrained due to taboos upheld by journalists, especially in relation to anything related to immigration. Research on these immigration-critical alternative media (ICAM) is scarce and this paper presents results of a comparative quantitative content analysis, where articles from the most important ICAM is compared to articles from MSM. Through this comparison it is possible to characterize ICAM through the key points where they differ from MSM. The results suggest that they have a much narrower scope of topics (mainly politics, social issues, crime, war and conflicts) compared to MSM. They are also characterized by a much more negative tonality and critical perspective. Furthermore, the relationship between ICAM and MSM is studied through an analysis of how often ICAM refers and links to content in MSM. Over sixty precent of the ICAM articles contained references to MSM, suggesting a relationship of dependence, rather than just one of opposition. The results are discussed in relation to notions of filter bubbles, echo-chambers and cyberbalkanization.
