The present study investigated the role Migrant World Television in South Korea plays in the development of a multicultural society formed due to international migration, as well as the media’s underlying meanings. Based on diachronic data obtained from interviews and observations, this study demonstrated that Migrant World Television is a connecting link between communities of transnational migrants and civil societies in South Korea and has initiated a form of active media participation and social engagement for transnational migrants in the last decade. Through the empowerment of grass-roots migrant media, transnational migrants of various backgrounds have gained access to channels that allow their voices to be heard, enable the consolidation of social reform dynamics through mutual alliances, and facilitate active engagement in the process of social transformation in South Korea.
