The dub-vs-sub argument is older than streaming. It used to be a fight between anime fans on niche forums. In 2026 it has become a global question that defines how billions of viewing hours get delivered every month — and the data shows the answer is shifting faster than most streamers expected.
I've pulled the cleanest sources I could find: country-by-country dubbing data from the European Audiovisual Observatory MAVISE database, viewer-preference data from Preply and YouGov, Netflix and Crunchyroll public statements on subtitle activation, and the academic literature on dub vs sub viewer outcomes. Here is what the numbers actually say.
The map: who dubs and who subtitles
Europe is split almost exactly in half on this question, and the split is one of the most stable cultural patterns in media. The dividing line traces back to the 1930s, when sound film arrived and each country had to decide what to do with foreign-language content.
Strong dubbing countries: Germany, Austria, France, Italy, Spain, and most of Latin America. In these markets, roughly 85–95% of imported film and TV is dubbed for theatrical and prime-time TV release. Germany alone supports an industry of over 400 professional voice actors and around 50 dubbing studios. The German voice for Bruce Willis (Manfred Lehmann) is more famous in Germany than many native German actors.
Strong subtitling countries: The Nordics (Sweden, Denmark, Norway, Finland), the Netherlands, Belgium, Portugal, Greece, and most of Eastern Europe outside Poland and Hungary. In these markets, 80–95% of foreign content is subtitled rather than dubbed. Sweden subtitles around 90% of foreign TV; the Netherlands is similar. This is widely credited as one of the main reasons English fluency in these countries consistently ranks among the highest in Europe — children grow up reading subtitles on foreign cartoons rather than hearing their characters voiced in the local language.
The mixed and odd cases: Poland uses lektor — a single male voice reading all dialogue over slightly lowered original audio — for around 70% of TV imports, a format almost unique to that market. Russia historically used the same approach. Eastern Europe broadly splits between subtitling for cinema and lektor or dubbing for TV. China, Japan and Korea predominantly subtitle, though Japan has a sizable dub industry for kids' content.

The Gen Z shift: subs are gaining everywhere
What is genuinely new in the 2020s is that the country-level pattern is starting to crack along generational lines. Preply's 2024 US viewer survey found that 70% of Gen Z respondents (under 30) watch with subtitles "most of the time", compared to around 50% of all adult viewers. YouGov data on Americans under 30 shows the same pattern.
The shift is even sharper in traditional dubbing markets. Surveys from German broadcasting consultancies in 2023–2024 found that around 45% of German viewers under 25 now prefer Originalton mit Untertiteln (original audio with subtitles) for prestige drama, particularly for English-language Netflix and Apple TV+ content. That is unthinkable for the previous generation — Germans over 50 still overwhelmingly prefer dubs. France, Spain and Italy show similar generational splits, smaller in absolute size but in the same direction.
Two factors drive this: a generation that grew up on subtitled K-content and anime no longer perceives reading subtitles as friction, and the rising prestige of "original audio" for serialized drama where actor performance is a major part of the appeal.

The Squid Game moment: when subtitles became cultural
The 2021 release of Squid Game on Netflix was the inflection point. The show became Netflix's most-watched series ever (1.65 billion hours in its first 28 days at the time), and the resulting English-language discourse was almost entirely about whether to watch with the English dub or the original Korean audio. Korean-American TikTok creator Youngmi Mayer's viral thread arguing the English dub mistranslated significant cultural nuance was viewed tens of millions of times, and the "always watch with subs" stance became the dominant Western position more or less overnight.
Three years later, the effect is measurable. Squid Game Season 3 drew nearly 146 million views in its first 91 days in 2025, and Netflix's own data showed that subtitle activation on the show was significantly above the platform average even in traditional dubbing markets. The non-English series category as a whole now consistently produces top-10 global hits — 10 of the top 25 most-viewed Netflix shows in H1 2025 were in languages other than English, almost all watched at higher-than-average subtitle rates.
The cultural shift also created a smaller but loyal counter-trend: serious anime fans who fought the sub-vs-dub war for decades suddenly found mainstream audiences agreeing with them. Crunchyroll has reported that its subtitle viewership consistently outweighs dub viewership across all titles, with the gap widest on simulcast premieres where dubs lag the Japanese release by weeks or months.
What the research says about viewer outcomes
This is where the data gets interesting for anyone running a streaming platform or learning a language. A 2024 academic review in Translation Spaces covering 40+ subtitle/dub studies found three consistent effects.
Engagement. Viewers who actively choose subtitles complete more episodes per session and rate non-English shows higher on average. The effect is modest (single-digit percentage points) but consistent across studies and platforms. Netflix internal data, surfaced by executives in 2022–2023 interviews, has been quoted as showing the same pattern.
Comprehension and retention. For factual content (documentaries, news), dubbing produces marginally higher comprehension because viewers do not split attention between text and image. For drama and comedy, subtitled viewing scores equal or higher on plot recall — the original-audio prosody appears to carry information that even well-acted dubs lose.
Language learning. This is the clearest finding in the literature. Subtitled content is unambiguously better for language learning because viewers actually hear the target language. Dubs strip out the input the learner is trying to acquire, leaving only visuals. The 2025 study in the British Journal of Educational Psychology showed that bilingual subtitle setups — both languages shown simultaneously — produced the strongest vocabulary gains, outperforming either L1-only or L2-only conditions for intermediate learners.
The streaming platform reality
Streaming has not so much resolved the dub-vs-sub question as exploded it. Every major streamer now ships both options for almost every major release, defaulting based on region — but viewers can switch at any time. That is the genuinely new development: the country-level pattern that was almost untouchable for 80 years is now a default setting two clicks away from being overridden.
Netflix's average release in 2025 ships with around 30+ subtitle tracks and 12–15 dub tracks, with K-content and prestige originals frequently hitting 40+ subtitle languages. Disney+ averages around 25 subtitle tracks and 10 dubs. The gap between subtitle and dub coverage has widened consistently — subtitles are 5–10× cheaper to produce per language than full dubs, and as AI-assisted subtitle translation tools mature, the cost curve is bending further toward subtitles being shipped everywhere by default and dubs being reserved for major markets and children's content.
The flip side is also true: even with broad subtitle coverage, the languages a given show ships with are often a fraction of the languages its viewers want. A Spanish-language Netflix original might ship with 30 subtitle languages on launch, but a Turkish viewer watching an obscure Korean indie series may find only English subtitles available — or none — in the country they live in. This is the persistent gap that real-time translation tools fill.
What this all means
Three things are clear from the data:
One: the country-by-country pattern is real but eroding. Germany still dubs, Sweden still subtitles, but the under-25 demographic in dubbing countries is increasingly aligned with the subtitling default. Streamers are responding by elevating subtitle UX even in markets where dubs are the historical norm.
Two: original audio is winning the cultural prestige war. Squid Game changed the conversation in 2021, and three years of data show the pattern has stuck. For drama and non-English content specifically, original audio with subtitles is now the default among the most engaged viewers globally.
Three: subtitle coverage is the next bottleneck. Now that most viewers will accept (or prefer) subtitles, the question shifts to which languages are actually available — and the answer varies wildly by platform, region and content type. Tools that fill the gap by translating subtitles in real time are filling a demand that streamers will not close on their own at the pace the data suggests they need to.
That gap is what Sublo exists to close. Sublo translates the subtitles already on the screen — on Netflix, Disney+, HBO Max, Amazon Prime, Apple TV+, Crunchyroll, YouTube and the rest — using Gemini AI, into 40+ target languages. Including dual-subtitle mode for learners who want the original-audio + bilingual configuration the research supports. Install once and stop thinking about which platform supports which language.
The short version
Germany still dubs 90% of foreign content; Sweden subtitles 90%. But Gen Z in every market is shifting toward subs, and original audio has won the prestige war for serialized drama. Streamers are responding with broader subtitle coverage and narrower dub investment, but the country-by-language gap remains wide enough that real-time translation tools are the practical workaround for serious viewers.
If you want to watch foreign-language shows on Netflix, Disney+, HBO Max, YouTube and 8 other platforms with subtitles in your language — or dual subtitles for language learning — Sublo translates them in real time.
