Not the famous companies — all 248 of them. Every listed Korean company filing under broadcasting, film and audio production, or publishing, from the 2025 annual reports. 68,809 people.
| Group | Companies | Staff | Avg tenure | Women | Avg pay | Company age |
|---|---|---|---|---|---|---|
| Broadcasting | 12 | 6,393 | 10.33 yr | 47.5% | ₩87.0m | 31.5 yr |
| Film, video and audio production | 40 | 10,540 | 7.32 yr | 56.9% | ₩63.1m | 25.7 yr |
| Publishing (includes games) | 196 | 51,876 | 5.44 yr | 34.1% | ₩77.4m | 22.5 yr |
| All content companies | 248 | 68,809 | 6.18 yr | 38.8% | ₩76.1m | 23.9 yr |
| Every listed Korean company | 2,779 | 1,865,198 | 11.29 yr | 28.0% | ₩95.1m | 43.5 yr |
Every group figure is weighted by headcount, so a 3,000-person studio and a 40-person label each count for their own staff rather than one company one vote. The last row is the same field on the same filing for the whole market — it is a baseline, not a ranking.
Broadcasting is 12 companies with 10.33 years of average tenure, the longest in Korean content and close to the market as a whole. Publishing and games sit at 5.44.
Set that against what those companies sell abroad. Terrestrial broadcasters were 81.5% of Korea’s television exports in 2012 and 7.2% in 2024, while independent producers went from 7.2% to 51.4% — the thirteen-year table is here. The export trade moved from the long-tenure companies to the short-tenure ones. The filings and the trade statistics are separate sources and we are placing them side by side, not claiming one caused the other.
Tenure is weighted by headcount, so each figure is the average tenure of a person working in that group rather than of a company. Companies are then banded by their own age, so the comparison holds firm age roughly fixed.
| Content (248 firms) | 6.18 years | 23.9 years old |
| Everything else (2,505 firms) | 11.49 years | 44.3 years old |
Content companies hold staff 1.86× less long, and they are 20.4 years younger. Band both sides by the companies' own age and the gap narrows — but it does not close.
| Company age | Content firms | Their tenure | Everyone else | Ratio |
|---|---|---|---|---|
| under 15 years | 68 | 3.91 yrs | 8.07 yrs | 2.06× |
| 15 to 30 years | 144 | 6.18 yrs | 9.37 yrs | 1.52× |
| 30 to 50 years | 35 | 8.39 yrs | 11.1 yrs | 1.32× |
| 50 years or more | 1 | 9.5 yrs | 13.6 yrs | — |
Across the 3 bands we will read, the ratio runs from 2.06× down to 1.32×. Holding firm age roughly fixed takes the gap from 1.86× to 1.32×, and never to 1. Being younger explains some of it, not most of it.
One band is left unread — the rule is fewer than 5 companies on either side. A band with fewer than 5 companies on either side reports no ratio, because a ratio over four companies is a reading of four companies. And these are listed companies only. Listed companies only. Much of Korean content production is unlisted and files none of this, so nothing here describes those firms. 2,753 companies disclose tenure, headcount and incorporation year, and every figure here uses those same rows.
Broadcasting holds staff 10.3 years, film 7.3, publishing and games 5.4. Pay runs the other way from what that suggests: film pays ₩63.1m against publishing's ₩77.4m while keeping people longer.

Film, video and audio production is 56.9% women. Publishing and games is 34.1%. Both sit above the whole listed market. The 22.8-point gap inside one sector is the larger fact and the filings do not explain it.
8 August 2026
Content firms average 23.9 years old against 44.3 for the rest of the listed market, and you cannot have long tenure at a young firm. Band companies by their own age and the tenure gap narrows from 1.86× to 1.32× — it never closes.
8 August 2026
Terrestrial broadcasters were 81.5% of Korea's TV exports in 2012 and 7.2% in 2024. Their staff average 10.3 years of service — the longest in Korean content. The producers who took the trade average 5.4 to 7.3.

Netflix's Korean catalogue has been watched 23.7 billion hours. The listed companies in that business keep staff 5.5 years against 11.3 across Korea's listed market — and their two halves are mirror-image workforces.

Fourteen of these companies — the best-known agencies and game studios — are broken out individually on the workforce page.
Two more tables sit on the company side of our data. Label reach counts how many readers each label's roster draws in English, and reach per artist divides that by the number of artists — which is where a label carried by one name stops looking like a label with a roster.
