Why Korean dramas are filmed while they are still being broadcast to viewers
In short: The high-stakes world of K-drama production relies on a unique live-shoot model. Because scripts are often unfinished, crews film episodes while the series is already airing. This allows production teams to pivot plotlines and character screen time in real-time based on audience feedback, creating a uniquely responsive viewing experience.
The Korean drama industry operates on a high-pressure schedule that defies standard international television production norms. While the first four episodes of a series are typically completed in advance, the remainder are shot continuously during the broadcast run. This live-shoot model is so demanding that actors often resort to 'jjok-jam'—a term for irregular, uncomfortable naps taken on set—to manage the exhaustion of filming while episodes are already airing. In extreme cases, production teams have been known to deliver 70-minute episodes to stations in ten-minute installments, with the final scenes being cut while the earlier parts are already playing on screens nationwide.
This frantic pace is driven by a desire to maintain total flexibility. Because scripts are not finalized before production begins, writers and directors can adjust the narrative based on viewer feedback and ratings. If a character becomes unexpectedly popular, their screen time may increase, or plotlines may shift to align with audience expectations. This responsiveness is a defining feature of the industry, though it comes at a cost; the intense pressure has historically led to production delays, budget overruns, and, in rare instances, severe financial instability for production companies unable to meet their obligations.
The industry’s structure has evolved significantly since the 1960s. Originally, actors were salaried employees of major networks like KBS and MBC under an exclusive 'Gong-chae' recruitment system. By the 1980s, the industry shifted toward a more merit-based, flexible model. Today, production is largely outsourced to independent companies, and the rise of global streaming platforms like Netflix has transformed K-dramas into a massive economic engine. In 2022 alone, South Korea sold US$561 million in television content abroad, a figure that now surpasses major industrial exports like electric vehicles and secondary batteries.
Despite the shift toward global streaming, the core of the K-drama remains deeply rooted in Korean cultural values, blending traditional Confucian themes with modern individualism. While genres now range from horror comedy to legal thrillers, the industry remains a powerhouse of female creative talent, with women accounting for 90% of the screenwriting profession. Whether through the 'fusion sageuk' historical dramas or contemporary office satires, the industry continues to balance its intense, real-time production methods with a global ambition that has turned local stories into a worldwide phenomenon.
