But that's the most interesting part of the article - that Amazon and HBO projects are being worked on by NORTH KOREAN workers!!! I totally agree with the HN headline and I'm glad it got me to click and read the entire article.
It's also wild that it somehow makes financial sense to outsource a core input into your product. A company that makes animations outsourcing animation makes as much sense to me as a software company outsourcing engineering. Though we do have a plane company that outsources making planes, but that's going some sort of way right now...
But anyway studios have been outsourcing animation work to Asian countries for a while now.
You might have seen some of the work product from one of the larger Japanese animation studios: TMS Enterainment who has worked on things like Batman: The Animated Series, Batman Beyond, The New Batman Adventures in addition to shows like Tiny Toon Adventures and Transformers in the 80-90s.
Some more recent(ish) examples are Cartoon Network outsourcing the animation for Steven Universe to Rough Draft Korea located South Korea and Nickelodeon outsourced some of the work for Korra to a Japanese company called Pierrot.
I'm just rambling at this point so I'm going to just leave a few links below that can do a better job of illustrating than I'm able to.
