Korean pop culture, in numbers

Screen

Korean titles reach the world two ways, and the average of them describes neither

Among 166 Korean titles that reached 20 countries or more, the first week already holds a median 39.1% of the countries they ever reach. But 58 of them started under 25% and 33 were nearly everywhere at once.

We set out to find the gateway market: the country a Korean title shows up in before it shows up anywhere else. The answer was that there is not one. Among the 166 Korean titles that reached 20 countries or more on Netflix’s weekly lists, the middle title is already in 14 countries in its first charting week.

So the question changed. Not where does it start but how much of the journey is already over when it starts.

The first week is most of a median title’s map

Median
Countries reached in the end 43
Countries in the first week 14
Share of the footprint already there 39.1%

Two fifths of everywhere, in week one. That is a fact about how Netflix charts move, and on its own it would suggest a single pattern: titles land, then top up.

They do not. There are two shapes

Share of countries reached in week one Titles Share
under 25% 58 34.9%
25–49% 42 25.3%
50–74% 33 19.9%
75% or more 33 19.9%

The two ends are nearly the same size. 58 titles built their footprint over weeks; 33 had it almost immediately. The median of 39.1% sits between two groups and describes neither of them — which is what a median does when the thing underneath is not one thing.

Built week by week

Title Countries In week one Share First week Started in
Ballerina 89 1 1.1% 2021-10-24 New Zealand
Black Knight 79 1 1.3% 2021-08-01 Bahrain
Happy Ending 47 1 2.1% 2022-11-27 Thailand
Land 43 1 2.3% 2023-01-01 Turkey
Sweet Home 42 1 2.4% 2023-11-12 Thailand

Ballerina charted in one country and ended up in 89. Nothing about that first country looks like a launchpad — New Zealand, Bahrain, Turkey are not where a Korean title is usually seeded, and no two of these five started in the same place.

An obvious objection is that our archive might simply have carried fewer countries in the early weeks, making an old title look like it began alone. It did not: the archive holds the same 93 markets in every one of the 265 weeks, minimum 93 and maximum 93. A one-country first week is a fact about the title.

Everywhere at once

Title Countries In week one Share First week
Humint 67 67 100% 2026-04-05
Outlaw 53 53 100% 2024-09-15
Dynamite Kiss 52 52 100% 2025-11-16
Physical: Asia 44 44 100% 2025-11-02
The Devil’s Plan 23 23 100% 2023-10-01

These titles never added a country after week one. Every market they were ever going to reach was reached in the same seven days.

Films land; series accumulate

Across the 54 films in this set the first week holds a median 50.0% of the eventual footprint. Across the 112 series it is 37.8%. A film has one week to be found. A series can pick up a market in its third week, and often does.

What this changes for someone shipping a title

If a catalogue is mostly films, the marketing question is are all the markets ready on the same day, because a film that misses week one has largely missed. If it is mostly series, the first week is a start rather than a verdict, and a market that stays quiet for a fortnight has not yet said no.

The dangerous move is to plan against the median. 39.1% is a number no title in this set behaves like. The full band table, both tails, and the format split are on the arrival table. Whether a title’s run at home says anything about any of this is a separate question, and we measured that too: the home-and-abroad table.

What this does not say: when Netflix released anything. We see the week a title appears on a country’s top 10, which is not the week it became available there. A title released everywhere on one day can still take a month to chart in half of those countries — and that gap is exactly what the table above is measuring.

Where these numbers come from

Sources

What we checked

  • The archive carries the same 93 markets in every one of the 265 weeks — minimum 93, maximum 93 — so a title showing up in one country in its first week is a fact about the title and not about thinner early coverage
  • Titles reaching fewer than 20 countries are excluded from every share, because a first-week share computed on three countries carries no information
  • The collector refuses to write its file if any single band holds more than 60% of the titles, because the finding is that there are two shapes and a single crowded band would mean there is only one
  • First-week country counts are checked against the named list of those countries, so a count cannot drift from the names printed beside it

What we left out, and why

  • Release dates. We see when a title appears on a country's top 10, not when Netflix made it available there, and the piece never treats the two as the same
  • Any word for why a title spread. A country can be added because more people started watching or because the titles above it fell away, and we cannot separate those
  • Viewing. A top 10 is a rank list; a title outside it is invisible here at any level of watching
  • Russia, whose list Netflix stopped publishing in February 2022
  • The word gateway. We went looking for one and the data says there is not one — the median travelling title is in 14 countries in the same week
