Why do kdramas only have one season

Overview

Korean dramas, commonly called K-dramas, have developed a distinctive single-season format that differs significantly from Western television series. This approach emerged from South Korea's television industry structure that developed in the late 20th century. Major broadcasters like KBS (Korean Broadcasting System), MBC (Munhwa Broadcasting Corporation), and SBS (Seoul Broadcasting System) established production systems where dramas typically run for one complete story arc. The format became standardized in the 2000s with most dramas airing twice weekly (Monday-Tuesday or Wednesday-Thursday slots) for 8-10 weeks. This contrasts with American television's seasonal model where successful shows might continue for 5-10 seasons. The single-season approach allows for tighter storytelling and complete narrative resolution, which has become a hallmark of Korean television drama production. Historical examples include landmark dramas like 'Winter Sonata' (2002) with 20 episodes and 'My Love from the Star' (2013-2014) with 21 episodes, both following the single-season format that has dominated Korean television for decades.

How It Works

The single-season K-drama model operates through a pre-production system where most episodes are filmed before airing begins. This differs from Western television's often simultaneous production and broadcasting approach. Korean drama production typically involves: 1) Complete script development before filming begins, 2) Casting of lead actors who commit to the entire series, 3) Filming of approximately 70-80% of episodes before broadcast starts, and 4) A fixed episode count determined during pre-production. The production timeline usually spans 4-6 months from initial planning to final broadcast. This system allows for consistent quality control and prevents the need for mid-season adjustments based on ratings. The limited episode count (typically 16-20 episodes) enables writers to craft complete character arcs and plot resolutions without stretching stories unnecessarily. Broadcasters schedule these dramas in specific time slots (often 10 PM KST) with predetermined end dates, creating event television that viewers can commit to for a defined period.

Why It Matters

The single-season format significantly impacts both Korean television economics and global viewing patterns. For production companies, this model provides predictable budgeting and scheduling, reducing financial risks compared to multi-season commitments. It allows actors to take on multiple projects annually rather than being tied to long-running series. For international audiences, particularly through streaming platforms like Netflix and Viki, the format offers complete stories without indefinite waiting for resolutions. This has contributed to the global K-drama phenomenon, with shows like 'Crash Landing on You' (2019-2020) and 'Squid Game' (2021) demonstrating how single-season narratives can achieve massive international success. The format also influences storytelling techniques, encouraging tighter plotting and character development within limited episodes. As streaming services increasingly commission Korean content, some adaptations of the traditional model are emerging, but the single-season approach remains dominant in Korean television production.
