Since the early 21st century, Hallyu creators have developed new forms of transnational practices. With increasing numbers of non-Korean members in K-pop idol groups, local music has become more transnational than ever before. Hallyu has also increasingly been integrated into global streaming services like Netflix, as the recent successes of Okja (2017) and Kingdom (2019) proved. The arrival of multinational streaming services has intensified the transnational nature of television production by revolutionizing South Korean cultural creators’s connection to global audiences. And with webtoons becoming new sources for global television dramas, films, and anime, transmedia storytelling has become a new form of transnationalization. Together, these forces have transformed how Hallyu has been crossing and remaking boundaries. This roundtable pushes the empirical and theoretical limits of the existing studies of Hallyu to map out its new developments across different geo-cultural areas, including East Asia, North America, Latin America, and Europe. Through the collective discussion of five panelists, it also seeks to articulate how Hallyu is establishing new paradigms of global cultural transnationalization. We actively exchange our ideas and findings with audiences who are interested in the dynamic process and diversity of the global penetration of Hallyu. Jihyun Ahn, associate professor at the University of Washington at Tacoma, presents her research on K-pop’s shifting new boundaries. Ju Oak Kim, assistant professor at Texas A&M International University, offers her perspective on the changing modes of television production and circulation in the era of streaming services. Wonjung Min, adjunct assistant professor (History and Asian Studies) at the Pontificia Universidad Católica de Chile, shares her field research on the formation of Hallyu fan culture in Latin America. Meanwhile, Kyong Yoon, associate professor (cultural studies) at the University of British Columbia at Okanagan, discusses the recent transnational and digital activism of K-pop as can be seen in the #BLM (black lives matter) movement. While moderating the roundtable and the interactive discussion with the audience, Dal Yong Jin, distinguished SFU professor (Communication) at Simon Fraser University, Canada, also contributes his own observations on new theoretical trends in Hallyu studies.
