Korean pop culture, in numbers

Korean series that aired on a Korean network, and those that did not

A Korean series can reach a Netflix chart by two routes: it aired on a Korean television network and was licensed on, or it was made for streaming and never had a broadcast run. Split the charting series on that line and the two halves do not look like the same business.

Korean series that aired on a Korean television network and Korean series that did not — do they travel the same way?

The two groups, side by side

How this is counted. Reach is the number of markets a title appeared in at least once, out of 93. A place is one appearance in one country's weekly top 10.

The median series without a broadcaster on record reaches 9.8 times as many markets as the median series with one, out of 93. 79 of the 238 network series charted in a single country and never travelled at all; 1 of the 49 did. Between them the two groups hold 24,515 chart places.

The network route is not the losing one

It would be easy to read the table as one pipeline beating another. It does not say that. The 238 network series hold 14,847 chart places — 60.6% of everything Korean series took — against 9,668 for the other group. There are simply far more of them, each travelling less far. Two different businesses, both working.

The two groups also differ at the top of the chart: 65.3% of the no-broadcaster group reached number one somewhere against 32.4% of the network group. That follows from reach — a title in 39 markets has more chances at a number one than one in 4 — and is not a separate finding.

What we are actually reading, and why it might be wrong

We are reading "Wikidata records no first broadcaster" as "it did not air on a Korean network". That is a proxy, not a confirmed fact. What supports it is that every title in that group carries other company credits — the record is not blank, only the broadcaster field is — and that the group is the recognisable made-for-streaming slate.

The no-broadcaster group at 60 markets or more, alphabetically: All of Us Are Dead, Bloodhounds, Gyeongseong Creature, Hellbound, If Wishes Could Kill, Mask Girl, Mercy For None, Money Heist: Korea - Joint Economic Area, Oasis, Squid Game, The 8 Show, The Art of Sarah, The Glory, The Trauma Code: Heroes on Call, The WONDERfools. Alphabetical, not ranked. Read the list and judge the proxy for yourself — that is why it is printed rather than summarised.

Films go the other way, which is why we are not generalising

Among films the direction reverses, on much smaller medians. So this is a fact about Koreanseries, not a fact about streaming, and we are not going to write it as one. A film's broadcast history is also a weaker signal — films reach television after cinemas, if at all.
