Korean titles travel 2 ways. The average describes neither

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 170 Korean titles that reached 20 countries or more on Netflix’s weekly lists, the middle title is already in 16 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

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

The two ends are nearly the same size. 58 titles built their footprint over weeks; 38 had it almost immediately. The median of 40% 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

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 268 weeks, minimum 93 and maximum 93. A one-country first week is a fact about the title.

Everywhere at once

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 55 films in this set the first week holds a median 50.8% of the eventual footprint. Across the 115 series it is 38.1%. 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. 40% 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.

What changed on 3 September 2026

Every figure in this piece was recounted against a rebuilt Korean title list, and this piece had a second problem of its own: its summary line and its opening paragraph disagreed with each other. The summary said 165 titles, the first paragraph said 173. Neither was the count. Both now read 170, which is what the data holds.

The shape of the finding is unchanged: the two ends of the distribution are still nearly the same size, and the median still describes neither of them. What changed is that a check now reads every one of these numbers out of the counted data on each build, so a figure cannot sit here disagreeing with the paragraph above it — or with the data — for weeks without the build going red.
