From outside Korea, 16 episodes can look like a storytelling form, the K-drama version of three acts. I don’t blame anyone for reading it that way. Yonhap still described the typical Korean series that way in 2020: 16 episodes, two a week, and a closed ending with no second season.
It’s plainer than that. Asia Today noted in August 2026 that dramas used to be built at 16 episodes to fit a slot of two nights a week for eight weeks. The standard used to be even longer. Hankook Ilbo points out that Korean hits up to the early 2000s, like Sandglass and All In, mostly ran 24.
That same Yonhap piece was about a show breaking the slot. tvN’s Hospital Playlist aired once a week, with episodes of roughly 90 to 120 minutes, and wrapped its first season in 12. I find that the clearest sign the count followed the calendar.
Paid by the episode
What kept the number in place was money. Korean broadcasters settle drama fees based on per-episode production costs, Hankook Ilbo reported in 2024, while streaming platforms buy rights against the total budget, with no minimum episode count. A producer told the paper that when TV was the only platform, they’d fit a drama to 16 or 24 episodes somehow, to suit the broadcaster. Now they plan 4 to 10 freely.
Ads were counted in sixteens too. Korean press calls the format sibyuk-bujak (16부작, “16-parter”), and Herald Business reported in 2022 that product placement deals set how often and how long a product appears on a 16-episode basis, and mid-roll ads work the same way. Shorter dramas also mean a network has to schedule more of them each year, which costs more.
The same piece noted that viewers had long pointed to excessive flashbacks and product placement unrelated to the plot in some dramas. I think the payment math explains that drag better than any theory about Korean storytelling. If the fee and the ad deal both assume 16, there isn’t much reason to write 12.
Shorter isn’t cheaper for everyone
Hankook Ilbo’s report adds that Studio Dragon’s dramas aired 42 TV episodes in the second quarter of 2024, down from 83 a year earlier, and the company cited that drop when its operating profit fell 35.7%. A producer told Asia Today that cutting episodes doesn’t shrink the budget at the same rate, because sets and lead casting are fixed costs.
TV has moved anyway. SBS’s Kim Bujang ran 10 episodes this summer and was a ratings hit. Asia Today says viewers who’ve gotten used to jeongjuhaeng (정주행, “driving straight through”), watching a whole season in order, tire quickly of repeated conflicts and side plots that wander off from the main story.
Not everyone reads this as progress. Drama critic Gong Hee-jung told Hankook Ilbo that short dramas focus on the lead’s story, so it’s harder to find ones where a lot of characters get room. She pointed to viewers going back on YouTube to Love and Ambition, a 1987 MBC weekend drama that ran 96 episodes.
