The rise of South Korean TV formats has been significantly driven by the institutional framework formed through public–private partnership. In addition to the media conglomerates’ active engagement in the format market, the Korea Creative Content Agency (KOCCA) and the Korea Format Alliance (KFA) have provided supportive policies and market intelligence, and the private institutions have contributed through initiatives such as the Format Lab Project. This network has created a favorable environment for format development, financial support, talent cultivation, creative incentives, intellectual property protection, and international collaboration. As a result, South Korean format producers have been able to keep pace with global format trends and successfully expand into overseas markets. One of the most successful format is the genre of the real-variety shows, which integrated local variety show elements and imported reality TV formats. This genre exemplifies South Korea’s distinctive form of cultural hybridity under television globalization. This study analyzed the format production network behind one such real-variety show, Grandpas Over Flowers—including its producers, writers, and technical teams. The results showed how this show embodies the three key success factors of international reality formats: casting, setting, and editing. Through these creative and technical practices, South Korea has effectively challenged the traditional center–periphery model of television globalization, repositioning itself from a peripheral participant to an influential central innovator in the global format market.
