Youth Media and its Digital Afterlife traces how youth-generated media changes after it’s been released to the public. The research highlights contested cases in which young people’s projects have fundamentally shifted, in terms of their scope and scale, and what’s at stake, as a result of the post-publication activities of readers, viewers, users, and community members. Projects of interest, which include media stories and youth-designed mobile apps, fall into one of three inter-related areas: journalism, arts production, and advocacy efforts. Working in conjunction with the MAPP team, the study examines the tricky role of “youth voice” in political organizing and messaging, and identifies implications of youth media’s digital afterlife for how we understand, investigate, and support young people’s engagement in participatory politics.
