A three-dimensional model of news recirculation: towards a unified understanding of news sharing.

This paper responds to calls for theory-building about news sharing on social media, arguing for a unified understanding of sharing practices both online and off. Developing a theoretical understanding of news sharing requires broadening our gaze to include other communicative technologies, such as postal mail, email, voice calls, and in-person conversation. In a conceptual contribution based on reflections about my participation in long-term multi-method collaborative studies in the US, I argue that news sharing is an act of commitment at the core. I also propose a three-dimensional model of news recirculation. The first two dimensions, publicness and ephemerality, are ideological - although they widely misrecognized as properties of specific channels and platforms. People enact a third dimension of practice, voice, when they recirculate news.
