This themed issue of MIA advances our understanding of how digital media are implicated in processes of change. It interrogates how people engage digital media in creative practices that lead to interventions in their own or others' lives, and explores the intentionalities through which they do this, and the processes and experiences such activities involve. The intention is to bring to the fore the idea of intervening as a way of being active in the world as a scholar, creative practitioner, activist or simply someone living their everyday life in ways that seek to generate forms of change. The articles in this issue address the use of creative interventions for affective and community-constructing ends, examining and highlighting the conscious use of the digital to disrupt and subvert existing patterns in communication and culture, heralding new possibilities while promoting inclusivity and social innovation.
