Global networks of information and interactions have created new conditions for access to myriad literacies, languages, and communities. Engagements with transnational texts and communities can support the imagination of lives different from one's local context. This article presents data from two qualitative studies of adolescent literacy practices about popular‐culture texts produced in Korea. Although these adolescents did not reside in Korea, the authors found that they constructed transnational spaces through these multimodal literacy practices: imagining different lives and engaging in multilingual mediascapes. Adolescents in both studies expressed a sense of belonging not exclusive to their places of residence. The findings support the argument that multimodal literacy practices developed through engagement with another country's popular‐culture texts support imaginative identity construction. These findings have implications for researchers and educators interested in multimodal literacies, digitally mediated learning, multilingualism, and transnational studies.
