In this article, we explore the history of Swedish newspaper carriers through the lens of the union struggles within the Swedish Transport Workers’ Union. This focus allows us to make visible the influence of a profession that has largely been overlooked in media history. Mobilizing around working conditions, the workers put pressure on the newspapers in terms of the size and weight of the papers with consequences for the editorial work. There was also a strong stance against commercial advertising and additional supplements that had consequences for the financial situation of newspapers. Hence, through their union struggles newspaper carriers directly influenced the outlook of newspapers in Sweden in the post-war era. In extension, we consider newspaper carriers as soft media infrastructures that had a crucial role and influence on the formation of the Swedish public.
