Non-English programming moved from niche shelf to center of catalog after Squid Game became Netflix's most-watched series debut ever in September 2021, reaching 111 million households in its first four weeks. Money Heist from Spain, Lupin from France and Dark from Germany had already hinted at the potential, but Squid Game turned it into doctrine. By the mid-2020s, platforms commissioned original series in dozens of languages, and Korean, Spanish and Turkish dramas regularly appeared in global top-ten lists alongside English titles.
What made international shows viable?
Technology, mostly. Dubbing and subtitles improved dramatically in quality during the late 2010s, and recommendation systems stopped sorting by language, pushing titles to viewers who never searched for them. Netflix, present in 190-plus countries, discovered that a hit anywhere was a hit everywhere if the algorithm found the right audience. Barriers that had defined the old television market, distribution borders and language gatekeeping, simply did not exist on global platforms. Money Heist, originally a modest Spanish network drama cancelled after one season, was revived by Netflix's international success and became a worldwide phenomenon.
Why was Squid Game the turning point?
Scale. Earlier international hits had large audiences, but Squid Game dominated every market at once, topping Netflix's charts in more than 90 countries and becoming a global conversation complete with Halloween costumes and reality-spinoff plans. It proved foreign-language content was not a supplementary category but a potential flagship, and its creator, Hwang Dong-hyuk, had shopped the script for about a decade before Netflix ordered it. Seasons followed in December 2024 and June 2025, each a global event, and the franchise became the clearest argument for the strategy.
What do platforms gain from local production?
Double value. A local original serves its home market with content broadcast networks cannot match in budget, and if it travels, the same investment pays off worldwide. Production outside Hollywood also costs less on average, so a Korean or Turkish drama that breaks out can deliver better returns than an American series with triple the budget. Global platforms now operate studios on multiple continents, and commissioning executives describe their slate as a portfolio of local bets with occasional global jackpots.
Which countries lead the trend?
South Korea became the flagship exporter, with dramas, thrillers and variety formats commanding worldwide audiences after 2021. Spain sustained a steady run of hits from Money Heist to later crime and teen series. France, Germany, Italy and Brazil each produced global breakouts, while Turkey's drama industry, already a broadcast export power, found new reach through streaming. Even smaller markets, like Denmark and Poland, hosted titles that charted internationally. The pattern rewards strong local industry infrastructure more than any particular language.
How did audiences change?
Viewers stopped treating subtitles as a barrier. Younger audiences in particular grew up reading captions even in their own language, and by the mid-2020s dubbing quality had risen enough that many viewers never noticed a title was foreign. Parasite's Oscar win for best picture in February 2020 had already signaled the cultural shift in film. On television, the algorithm did the quiet work: audiences who finished one Korean thriller were immediately served another, and preference clusters formed across borders rather than within them.
Are there limits to the global strategy?
Some. Cultural specificity does not always translate, and many local originals stay local, which platforms accept as the cost of serving home markets. There are also industrial concerns: production booms in Seoul, Madrid and Istanbul raised costs and strained crews, and creators in some countries have pushed back on deals that hand worldwide ownership to the platform. Regulators in Europe and elsewhere now require local content investment as a condition of operation, formalizing what had been a voluntary strategy.
What comes next for global content?
Deeper integration rather than novelty. Expect more co-productions that blend markets from the development stage, more format adaptations moving in every direction, and non-English titles treated as default tentpoles rather than discoveries. The lesson of the streaming decade is that audiences follow stories, not languages, and the platforms that internalized that first are now the ones everyone else imitates.
