A good TV series can feel strangely familiar, even when it was made somewhere else.
You might be watching a Korean drama with English subtitles, a Spanish thriller dubbed into French, or a familiar sitcom remade with a completely new cast in another country. The story is recognisable, but the language, humour, rhythm and cultural details have shifted.
That is TV localisation at work.
For many years, international TV adaptation often meant creating local versions of successful formats. A show that worked in the United States might be rebuilt for audiences in Poland, India, Turkey or the Middle East. Sitcoms, talent shows, game shows and dramas have all travelled this way.
Today, streaming has changed the picture. Audiences can discover series from almost anywhere, often within days or even hours of release. Subtitles, dubbing and multilingual audio options have become part of everyday viewing. Netflix, for example, reported that more than a third of viewing in the first half of 2025 came from non-English language titles. The platform has also expanded language choice on TV devices, giving viewers access to a fuller range of available subtitles and dubbing options.
But the basic challenge has not changed: a programme still has to make sense, feel natural and carry emotion in another language.
That takes more than translation.
TV localisation is not just changing the words
When people think about localisation, they often imagine subtitles appearing at the bottom of the screen. That is part of it, of course, but TV localisation goes much deeper.
Dialogue has rhythm. Characters have a voice. Jokes rely on timing. References can be obvious to one audience and meaningless to another. Even a simple family argument can carry different emotional weight depending on the culture watching it.
A literal translation might tell the viewer what was said. A good localisation helps the viewer understand what was meant.
That difference matters.
In a sitcom, the translator has to preserve the joke without making it feel forced. In a crime drama, the language has to sound believable without losing precision. In a reality show, the subtitles need to keep pace with fast, overlapping speech. In a children’s programme, the wording has to be simple, natural and age-appropriate.
None of this happens by accident.
Subtitles, dubbing or a local remake?
There are usually three main ways to bring a TV series to a foreign audience: subtitles, dubbing or full adaptation.
Subtitles keep the original voices and performances. They are often the best choice when the emotion of the original acting matters, or when viewers are comfortable reading while watching. But subtitles come with limits. There is only so much text you can fit on screen, and viewers need enough time to read it.
Dubbing replaces the original dialogue with spoken dialogue in another language. This can make a series more accessible and easier to watch, especially for children, family audiences or viewers who prefer not to read subtitles. But dubbing has its own challenges. The translated lines need to match the timing of the scene, the emotional tone of the actor and, where possible, the movement of the mouth.
Local remakes go even further. Instead of translating the original show, the format is rebuilt for another market. Characters may be renamed. Locations change. Family dynamics are adjusted. Jokes are rewritten. Social habits, food, work culture and even the way people argue can all be adapted.
This is why some comedy formats are remade rather than simply subtitled. The basic idea may be familiar, but the execution has to feel local. A family sitcom, for example, depends on much more than the plot. It depends on how people interrupt each other, what feels rude, what feels affectionate, what counts as embarrassing and what kind of humour the audience recognises.
The same logic applies far beyond television comedy. The more culturally specific the material, the more carefully it needs to be adapted.
Why some shows travel better than others
Some stories travel easily. Others need more careful adaptation.
A detective story built around a murder investigation may be relatively easy for international viewers to follow. The structure is familiar: crime, clues, suspects, resolution. The cultural details still matter, but the basic engine of the story is widely understood.
Comedy is much harder.
Humour is often built from shared assumptions. It depends on social awkwardness, class, accents, slang, timing, embarrassment and local taboos. A joke that lands perfectly in one language can become flat or confusing in another. Sometimes the translator can find an equivalent. Sometimes the joke has to be recreated. Sometimes it has to be replaced entirely.
Family dramas also need careful handling. Ideas about respect, parenting, marriage, gender roles, workplace behaviour and personal space can vary widely between cultures. A scene that feels warm and ordinary in one country might feel rude, cold or unrealistic in another.
This is where localisation becomes a creative discipline, not a mechanical one.
The goal is not to erase the original culture. Often, the foreignness is part of the appeal. The goal is to make sure the audience can follow the story, feel the emotion and understand the choices being made on screen.
Streaming has raised audience expectations
Streaming platforms have made international viewing normal.
A series no longer has to be remade before it can reach viewers in another country. Audiences are increasingly used to watching stories in other languages, whether through subtitles, dubbing or a mixture of both. Korean dramas, Spanish crime series, German thrillers, French mysteries and Japanese reality shows can now reach international audiences without being rebuilt from scratch.
That does not mean localisation has become easier. In many ways, expectations are higher.
Audiences notice awkward subtitles. They notice dubbing that feels wooden. They notice when a character’s personality seems to change because the translation has flattened their voice. They also notice when cultural references are overexplained or stripped of flavour.
Good localisation has to stay out of the way. When it works, viewers are not thinking about the translation. They are just watching the show.
What TV localisation can teach brands and content creators
The lessons from TV localisation are useful well beyond entertainment.
Businesses now produce huge amounts of video content: training videos, product demonstrations, brand films, internal announcements, webinars, investor updates, recruitment videos and social media campaigns.
Many of these are created in one language first and then shared across several markets. The temptation is to translate them quickly and move on. But video does not work like a brochure or a static webpage. It has voice, pacing, visuals, music, captions, facial expressions and on-screen text.
If the translation is too long, it may not fit the subtitle timing. If the voice-over sounds too formal, the brand may lose warmth. If on-screen text is not adapted, the viewer may miss key information. If examples are too local, international audiences may understand the words but not the point.
This is why video localisation needs to be planned, not treated as an afterthought.
Before translating a video, it helps to ask:
- What does the viewer need to feel?
- What parts of the message are culturally specific?
- Will subtitles be enough, or would voice-over work better?
- Does the script need adapting before translation?
- Are there graphics, captions or visual references that also need localisation?
These questions can make the difference between a video that technically exists in another language and one that actually works in another market.
Localisation protects the story
The best localisation does not make content feel generic. It protects what made the original work in the first place.
In TV, that might be the chemistry between characters, the pace of a joke or the emotional weight of a scene. In business video, it might be the clarity of a training message, the credibility of a spokesperson or the feeling behind a brand campaign.
Translation carries the words. Localisation carries the experience.
That is why TV and streaming are useful reminders of a much wider truth: audiences do not respond to language in isolation. They respond to tone, timing, context and culture.
