- A quarter fewer Korean titles reach a Netflix top 10 than in 2022. The space they hold did not shrink
Mon Aug 10 — 289 Korean titles charted somewhere in 2022 and 216 in 2025, while the places they held rose 7.9%. Remove each year's biggest title and the ten largest gained just 3.6 points — most of the concentration is one show returning.
- Korean films leave a Netflix chart exactly as fast as everyone else's. Korean series do not
Mon Aug 10 — Across 210,355 finished runs, a Korean film holds a country chart for 1.96 weeks on average and every other film for 2.02. Korean series run 3.7 weeks against 2.71 — and removing each group's biggest title barely moves it.
- A Korean series that opens at number one lasts six weeks. One that opens at ten lasts one
Mon Aug 10 — Opening position is the only fact anyone has on the first Monday. Across 8,324 Korean series runs it moves expected length by 0.56 weeks a step — against 0.44 for other series, 0.33 for Korean films and 0.22 for other films.
- Korean series are widest in week one only 20% of the time
Mon Aug 10 — Hold run length fixed and most of that gap closes — among titles that lasted five to eight weeks it is 26.6% against 28.6%. Among those that lasted nine weeks or more it does not close: 9.7% against 24%.
- At number one a Korean title has a 1.2% chance of being gone next week. At number ten it is 70.2%
Sun Aug 09 — Everything written about a chart is about getting on it. We measured 11,722 departures instead — the position a Korean title held the week before it vanished, against the 10.0% each rank would take if position did not matter.
- Korean titles are commonest in the middle of the chart — except in ten markets, where they own the top
Sun Aug 09 — Across 93 Netflix markets Korean titles hold 7.9% of chart places. In the 20 markets where their share runs 5–10%, they hold only 5.4% of number-one places. In the ten where they are strongest it inverts: 36.6% at number one against 27.4%.
- Our headline 7.9% is not one place a week — it is nothing, and then several at once
Sun Aug 09 — Korean titles hold 7.9% of Netflix country chart places. Spread evenly that would put at least one on 56.3% of country-weeks; the real figure is 42.0%. Empty weeks run 58.0% against 43.7%, and crowded weeks 4.0% against 0.6%.
- What a chart position does not tell you — and why it tells you least on the chart Korean titles sit on
Sun Aug 09 — Netflix attaches hours viewed to 10,720 global chart rows and to 0 of its 499,180 country rows. Knowing a rank narrows the possible hours by 47.3% on the non-English series chart — least of the four, and the one Korean titles sit on.
- Korea's Netflix chart led Southeast Asia for 51 of 421 Korean titles. Usually they enter the same week.
Sat Aug 08 — Of the 421 Korean titles that reached Southeast Asia's top 10, Korea's own chart got there first for 51 and in the same week for 165 — and never charted 151 of them at all. Series enter together; films scatter.
- Korean titles climb the Netflix chart after they arrive. Most other titles peak in week one.
Sat Aug 08 — Across 93 markets, 57.4% of Korean chart runs reach a higher rank than their opening week against 40.5% for everything else. Longer runs give more chances to climb — and the gap holds inside every run-length band.
- Six Korean titles fill half of America's Korean chart places. In Vietnam it takes 52.
Sat Aug 08 — Across 93 markets the typical Asian one has charted 247 different Korean titles and the typical market elsewhere 85. Matching markets by how many Korean places they hold removes a third of that gap. Two-thirds of it survives.
- Korean titles hold 7.9% of the world's top-10 places. Where they were strongest, the share fell by a third.
Sat Aug 08 — Across 93 countries and 265 weeks the global share has not moved since 2022. That average hides nine Asian markets where Korean titles held 30.3% of places and now hold 19.5% — all nine fell, and Korea's own chart did not.
- There is no K-drama season. The Korean share moves 2.5 points across twelve months — and 14.2 in a week.
Sat Aug 08 — Month by month, Korean titles hold between 6.6% and 9.1% of the world's top-10 places. Remove each month's biggest title and the band gets wider, not narrower. What moves this number is releases, not the calendar.
