This article engages with the history of Swedish prison papers, situating them as alternative media within the broader media landscape shaped by the emergence and dismantling of the welfare state. The article not only aims to give a descriptive account of the history of Swedish prison papers but also builds and further develops theorizations of alternative media by constructing them not in opposition to established media but as in dialogue and exchange with them. As we show, prison papers have had repercussions for mainstream discourses beyond catering to niche audiences. Therefore, we suggest that alternative media should be understood as part of the broader media landscape rather than being situated outside of it. This also has implications for how we conceptualize newly emerging alternative media, also called alt-media, that are not progressive but populist and right-wing oriented, as well as supportive of conspiracy theories.
