This article constructs a theoretical model of digital intermediation: a process of three key, and unseen, components for cultural production in our contemporary media environment. Digital intermediation is a content production and consumption process that incorporates the cultural characteristics of technologies, agencies and automation. First, the article describes the key components of digital intermediation that bring about the production and distribution of cultural artefacts. Second, the article describes digital intermediation as a process of production and consumption amid these three components. Third, the article articulates the problems digital intermediation creates by examining the loss of user agency over the production of and access to cultural artefacts. Finally, the article highlights how digital intermediation problems can be addressed by cultural institutions, specifically public service media, to shore up user agency within automated media environments.
