Fans watch the idols and the games. Almost nobody counts the people who run the companies behind them. These are 14 listed Korean firms, from their own filings — how long staff stay, how many there are, and who they are.
Company-reported average tenure across all employees, in years, from the latest annual filing. Shown in two groups because they are different kinds of business — not as one ranking.
K-pop labels, drama studios and broadcasters. These are younger businesses with high project turnover, and the average time an employee stays is correspondingly short.
Game publishers and developers. They are larger and, on this measure, keep staff longer than the agencies do.
Women as a share of total headcount, from the same filings. The two groups sit on opposite sides of the halfway line, and it is not close.
The entertainment agencies are majority-women workforces; the game studios are majority-men. A 50% line is the reference — this is a composition, not a score.
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.

This is not a ranking, and not a judgement. A short average tenure at a young company is not a worse number than a long one at an old company — it is a different one. We put the figures side by side and name the reason they differ.
Not included: privately held agencies and studios, which file no comparable disclosure. One company on our first list — DAEA TI (045390) — was dropped after checking its filing: it makes railway signalling equipment, not music or games.
