This volume brings together a range of papers that fruitfully engage with the theme of the 2017 Annual Conference of the International Communication Association, held in San Diego, California: Interventions. Here "intervention" points to a range of communication practices that engage with a political event, social phenomena, industrial or socio-cultural practice, in order to alter and disrupt events and the norms and practices that contribute to their occurrence.　 Interventions prohibit events from proceeding in a "normal" course. Interventions approach or critique practices and phenomenon resulting from tensions or absences occurring in: events, structures, (institutional governmental, media industry), discourses, and socio-cultural and subcultural events. Intervention presents the opportunity to explore boundaries, assumptions and strategies that appear to be different or irreconcilable, viewing them instead as possibilities for productive engagements. Communication interventions—in both research and practice—insert insights from diverse voices, marginal positions, emerging organizational practices and digital technologies, to broaden and enrich dialogue. Interventions bring complex reframings to events and phenomenon. Interventions seek to alter a course and effect changed practices in a range of spheres: governmental and social institutions, cultural and nongovernmental groups; industry and organizational life, new media and digital spaces, socio-cultural environments, subcultural groups, health environments, affective and behavioral life, and in everyday life.
