A quarter fewer Korean titles reach a Netflix top 10 than in 2022. The space they hold did not shrink

Netflix has announced a larger Korean slate for 2026. Its own charts have been moving the other way: 276 Korean titles reached a country top 10 somewhere in 2022, and 203 did in 2025 — a fall of 26.4% across the four full years we hold.

The obvious reading is that Korean titles are losing ground. They are not. The places those titles held went up. The full table, every year including the part years, is at fewer titles, same shelf; the company-level version of the same question is at did the charts concentrate.

Same shelf, a quarter fewer titles on it. Places per title rose from 26.5 to 36.6.

That last column is the one to distrust. It is one number divided by another, both of which moved, and on its own it cannot say which. So we took it apart.

Where the places went

The first column looks like a field closing up: the ten biggest titles went from holding 45.4% of every Korean chart place to 57.3%.

The second column is the same measurement with each year’s single biggest title taken out, and it tells a much smaller story — 42.8% to 46.6%, a gain of 3.8 points rather than 11.9.

The third says the rest of the field barely moved at all. A title outside the top ten held 15 places in 2022 and 16.4 in 2025.

So the concentration is not a thicker head. It is one title:

Between 2022 and 2024 the largest Korean title of the year took 6.5% to 8.3% of all Korean chart places. In 2025 one show took a quarter of them, and it is the same show that took 27.3% in 2021.

We are not naming a second or a third. One title holding a quarter of a year’s places is a fact about the shape of the chart; a list of the ones behind it would be a ranking, and we do not publish those.

What actually changed

Strip out the year that Squid Game returned and what is left is narrow but real:

• 73 fewer Korean titles reached a top 10 in 2025 than in 2022, and the number falling into the smallest band — five chart places or fewer across an entire year — went from 167 to 117.
• The places did not follow them out. Korean titles held 7,303 places in 2022 and 7,423 in 2025.
• The middle did not absorb them either. Places per title outside the top ten went from 15 to 16.4, which is a 9% rise across four years.

Fewer titles, the same shelf space, and no obvious beneficiary among the titles that are still there. The one place the arithmetic lands is the top: 2025’s biggest title held roughly 1,800 chart places against roughly 600 for 2022’s biggest.

That is the chart a 33-title slate is arriving into.

What this cannot tell you

It counts what reached a top 10, not what was released. A year with fewer charting titles may have had fewer Korean titles released, or the same number with fewer of them charting, and Netflix publishes no release counts by country of origin that would separate those. We cannot tell you whether the supply shrank or the chart got harder to reach.

It also says nothing about viewing. A top 10 is a rank list; a title just outside it is invisible here at any level of viewing, and the 73 titles that stopped charting may not have stopped being watched.

And a note on our own arithmetic: seasons of one show are counted as that show. Netflix lists seasons separately on its charts, and if we counted them separately a returning show would look like several new titles — which is exactly the thing this article is trying to measure.
