Book excerpt: Through a critical examination of the Korean diaspora in transnational contexts as a case study, Korean Digital Diaspora: Transnational Social Movements and Diaspora Identity unmasks the process of how people of the diaspora have built social interactions and communication with others online, how they have orchestrated social movements, and finally, how they have narrated and reshaped their diaspora identities in their everyday lives. Utilizing an ethnographical approach, including in-depth interviews, participant observation, and a field study in New York City and Philadelphia, Hojeong Lee delineates how digital media technology has expanded into a new form of diaspora, digital diaspora, within the Korean diaspora community, and how it has mobilized the social movements of Korean diaspora members. Accordingly, Korean diaspora members have begun to imagine their community as a transnational global diaspora. Korean Digital Diaspora concludes with an analysis of how the changed attitudes of diaspora members have also influenced how they define themselves and how they are reshaping their diaspora identities. This multi-site, three-year study reveals the nexus of media, individuals, and society, highlighting the transnational social movements of diaspora members.
