The economics of transmedia synergy: Analyzing global platform leverage in the post-2025 K-pop ecosystem

This research investigates the structural transformation of the South Korean "Hallyu" industry into a totalizing transmedia ecosystem by 2026. By utilizing a mixed-methods approach, the study analyzes the economic ramifications of two landmark events: the 83rd Golden Globe victory of the animated feature K-Pop Demon Hunters and the unprecedented $1.5 trillion KRW revenue generated by the BTS 2026 reunion. This paper theorizes the "Transmedia Multiplier Effect," a mechanism through which singular artistic products are scaled into multi-platform intellectual property (IP). The findings demonstrate that the transition from platform dependence to "Platform Sovereignty" via proprietary systems such as Weverse has enabled the K-pop industry to bypass traditional global intermediaries, maximizing revenue through digital labor and the "Hook Model" of fan engagement. This study provides a comprehensive framework for understanding the future of the global creative economy, which has redefined fan interactions by transforming passive consumption into active participation through immersive digital experiences. Moreover, the integration of data analytics within proprietary platforms allows precise targeting and personalized content delivery, further enhancing fan loyalty and monetization. Consequently, the South Korean Hallyu industry exemplifies a pioneering model of a global creative economy adapting to the digital age.
