A few days ago, I posted two videos that unexpectedly went viral and gathered about 1 million views together, on Instagram & TikTok.
The first was about something most Romanians do without thinking twice: we call sneakers Adidasi. Not Adidas sneakers. Just sneakers. Any sneakers.
What I thought was a local habit turned out to be much bigger than that. People from all over the world started commenting with their own versions. Xerox. Jeep. Pampers. Google. Brand names that had slipped into everyday language and started doing a different kind of work.
That was the part that caught my attention.
Because once a brand becomes the word people use for the whole category, something strange has happened. The brand has moved beyond the marketplace and entered language itself.
And that, to me, is one of the most fascinating things in branding.
What genericide actually is
There is a legal term for this phenomenon: genericide.
It describes what happens when a trademark becomes so widely used that it stops functioning as a brand name and starts functioning as the generic name for the product itself. At that point, the word no longer points to one company in particular. It points to the category.
From a cultural point of view, that sounds like the highest possible form of success. Most brands fight for recognition. A few achieve memorability. Almost none become so embedded in everyday speech that people use them without even noticing.
But from a legal point of view, that same success can become a liability.
A trademark only works if it remains distinctive. The moment the name stops identifying a specific source and starts naming the thing itself, the company’s claim over that word becomes weaker.
That is the paradox. A brand can become immensely powerful in culture while becoming more vulnerable in law.
Why this is such a powerful form of brand success
There is something almost mythic about a brand becoming part of ordinary language.
It means the brand no longer needs to introduce itself. It no longer needs to explain what it is or why it matters. The word has already taken root. It lives in memory. It gets repeated in conversation. It gets passed down casually, often without anyone knowing where it came from.
This is different from awareness.
Awareness is when people recognize the name.
This is when the name becomes the shortcut.
And shortcuts matter because language is full of them. We use words to compress reality into something manageable. A single term can carry an entire category, a set of expectations, a feeling of familiarity, even a sense of what is normal. So when a brand name becomes that shortcut, it has done more than win attention. It has become part of how people organize the world.
That is not just commercial success. That is cultural success.
Why the same success becomes dangerous
And yet this is exactly where the trouble begins.
What makes a trademark valuable is its ability to distinguish. It tells you who made the product. It signals origin. It preserves difference.
But once the public starts using the brand name as a generic term, distinction begins to blur. The word still circulates, maybe even more than before, but it no longer belongs to the company in the same way. It has been absorbed into common use.
That is why companies are often so defensive about language.
From the outside, it can seem excessive. Why would a company care so much about how people use a word? Why send warnings, corrections, legal notices?
Because they are not only protecting vocabulary. They are protecting distinction.
The fight is not really over grammar. It is over whether the word still points back to them, or whether it has drifted away and become public property.
The Aspirin example
Aspirin is one of the clearest examples of this.
It began as a Bayer trademark. But in the United States, the word eventually became generic. Over time, it stopped being understood as the name of one company’s product and became the general term for the product itself.
That is what makes genericide so interesting. It is not a story of a brand failing to spread. It is a story of a brand spreading so completely that it loses the very boundaries that once made it protectable.
In other words, the brand succeeds so thoroughly that it stops being experienced as a brand at all.
What this reveals about branding
I think this points to something deeper than trademark law.
It reveals that branding is not just visual, and it is not just commercial. Branding is linguistic. It is cognitive. It is cultural.
We often reduce branding to surfaces: logos, color palettes, typography, websites, campaigns. All of that matters, of course. But underneath those visible elements is something more fundamental. A brand is also a pattern in the mind. It is a set of associations that becomes easier to retrieve over time. It shapes what people notice, what they expect, and what they remember.
Language plays a major role in that process.
Words are not neutral containers. They guide perception. They simplify choice. They make one interpretation feel obvious and another feel distant. When a brand secures a place in language, it gains access to one of the strongest mechanisms of memory there is.
That is why this subject feels bigger than a quirky naming habit. It touches the core of what branding actually does.
When a brand crosses into culture
What interests me most is the moment a brand stops behaving like a company asset and starts behaving like a cultural object.
That is the threshold examples like Adidasi reveal.
At that point, the brand is no longer just being marketed. It is being spoken. Repeated. Inherited. Normalized.
And once that happens, the brand begins to move according to cultural logic, not just business logic. People use the word because other people use it. It spreads through imitation, convenience, and habit. It gets detached from the company that created it and woven into ordinary life.
The company may still own the trademark in a formal sense, but culture has its own rules. Culture does not ask who coined the word. It asks whether the word is useful, familiar, and easy to pass along.
That is why this whole phenomenon feels so revealing. It shows where branding ends and culture begins, and how thin the line between them can be.
The lesson for founders and brand builders
If you are building a brand, there is a lesson here, although maybe not the obvious one.
The goal is not simply to be known. Plenty of known brands are weak.
The goal is to become mentally available in a clear and distinctive way. You want people to remember you easily, but you also want that memory to remain attached to you. Not to the category in general. Not to a vague idea. Not to a commodity.
That means strong brands need two things at once: familiarity and distinction.
Too little familiarity, and nobody remembers them.
Too little distinction, and people remember the category but not the source.
The hard part of branding is managing both. You want to become intuitive without becoming generic. You want to become culturally legible without dissolving into the background. You want your name to travel, but not so far that it stops pointing back to you.
That is a subtler challenge than most branding conversations make it seem.
Why language matters so much
The more I think about this, the less I see it as a niche trademark issue and the more I see it as a language issue.
Language quietly structures behavior. It shapes what feels normal, what comes to mind first, what sounds interchangeable, what seems like the default. We rarely notice this because language works best when it feels invisible. But that invisibility is exactly what gives it power.
When a brand enters language, it enters that invisible layer too.
It begins shaping behavior not through persuasion alone, but through familiarity. Through repetition. Through the small efficiencies of speech and thought.
That is why companies fight over words so intensely. They understand that a word is never just a word. A word can become a position in the mind. And a position in the mind can become preference, habit, and choice.
Final thought
What began as a funny observation about Romanians saying Adidasi ended up opening a much larger question.
What does it mean when a brand becomes the word?
On one level, it is a sign of extraordinary success. Few brands ever become that deeply embedded in memory and culture.
On another level, it is a warning. The same process that makes a brand unforgettable can also erode its uniqueness.
That is the tension at the center of genericide.
A brand wants to become familiar enough to live in people’s minds, but not so diffuse that it stops belonging to itself.
And maybe that is one of the clearest reminders of what branding really is.
Not decoration.
Not exposure.
Not just recognition.
A struggle over meaning, memory, and language.
