In September 2021, a 23-year-old named Zaria Parvez was a little over a year into her first job out of Rutgers University, working as a global social media manager at Duolingo, the language-learning app. The company had a mascot, a green owl named Duo, that had existed largely as a static logo and an in-app notification character reminding users not to skip their lessons. Parvez was given the company's TikTok account with no real strategy attached to it and, by her own later account in interviews, little more than freedom to experiment.
She began posting videos of a person in a Duo owl costume behaving strangely: dancing badly, appearing to threaten users who skipped their language lessons, inserting itself into whatever meme format was circulating that week. There was no single viral video that made the account. There was a year, then two years, of near-daily posting, most of it unremarkable by any individual measure, building an audience that had no equivalent single moment anyone could point to as the turning point.
By 2023, Duolingo's TikTok account had tens of millions of followers, more than most media companies and a large share of Fortune 500 brands combined, and the owl had become, by several marketing industry rankings, one of the most recognized mascots on the internet, on the strength of a strategy that had produced no individual video capable of explaining the outcome on its own.
The ad everyone still remembers
In February 2010, Wieden+Kennedy released a television commercial for Old Spice featuring the actor Isaiah Mustafa, shot in a single continuous take, in which Mustafa addressed the camera directly while transitioning between a bathroom, a boat, and a horse. The ad, "The Man Your Man Could Smell Like," aired during the Super Bowl and was, by most measures available at the time, an immediate and significant success. Old Spice reported meaningful gains in body wash sales in the months following the campaign, and the ad has been taught in advertising and marketing courses for over a decade since.
Old Spice followed the campaign that July with a second phase, a series of short videos in which Mustafa responded in character to real comments and questions from viewers on social media, produced and posted within hours of each request, an approach that was itself considered innovative at the time.
What is discussed less often is what happened to Old Spice's marketing in the years after. The brand never produced a follow-up campaign that matched the cultural reach of the original, despite continuing to invest in comedic, high-production advertising built around the same tone and, in some cases, the same actor. The single campaign had generated an enormous spike in attention and a real, if temporary, increase in sales. It had not, on its own, produced a compounding audience that Old Spice could keep returning to.
Compounding rewards time, not drama
In a codicil to his will, signed shortly before his death in April 1790, Benjamin Franklin left a bequest of £1,000 each, roughly $4,400 at the time, to the cities of Boston and Philadelphia, with a specific and unusual instruction. The money was to be lent out to young tradesmen at interest, and the accumulated fund was to sit largely untouched for 200 years, with a partial disbursement permitted after the first 100.
Franklin wasn't leaving Boston money. He was leaving it time.
Franklin was not, by the standards of his era, an extraordinarily wealthy man leaving a fortune to be preserved. He was making an explicit bet on the mathematics of compounding: that a modest sum, left to accumulate without being spent, would eventually become substantial through nothing more dramatic than time and reinvestment.
By 1990, when the 200-year term expired, Boston's fund, invested somewhat more aggressively over the two centuries, had grown to roughly $5 million. Philadelphia's fund, managed more conservatively, had grown to a little over $2 million. No single year of either fund's history was in itself remarkable. The outcome existed only because nearly every year's gain had been permitted to remain inside the account and become the base for the following year's growth, for two hundred consecutive years, through wars, depressions, and currency changes that Franklin could not have specifically anticipated.
The shape both stories share
Old Spice and Duolingo were both, at different points, run by people with real creative skill, and both approaches required genuine institutional commitment to execute. The difference between them was never talent. It was whether the campaign was built to produce a single spike that would then have to be repeated from a standing start, or built to deposit into something that could keep compounding without needing to be re-earned from zero each time.
So you see: attention spikes. Distribution accumulates.
A campaign that spends its full effort producing one enormous moment behaves like a withdrawal against nothing: memorable, often profitable in the near term, but requiring an equally large new effort to produce the next moment, because nothing was left in reserve. A slower, more repetitive effort, one that looks, from month to month, almost too small to matter, behaves like Franklin's bequest: unremarkable in any single year, and only explicable in retrospect once the accumulated base has grown large enough for the same ordinary effort to produce a return that a single spectacular campaign never could.
It's worth being precise that this is not an argument that consistency alone guarantees an outcome. Duolingo's TikTok strategy required years of genuinely funny, well-produced content before the account's size made the strategy look, from the outside, as though it had been obviously correct from month one. A year of mediocre, unfunny posting compounds into nothing at all. The account still had to be worth watching, the same way Franklin's fund still had to be lent out competently for two centuries rather than simply left in a drawer.
What compounds and what doesn't
Once distribution is understood as compounding rather than transactional, a few instincts that feel reasonable turn out to be mistakes.
Old Spice's 2010 campaign remains, by most advertising industry accounts, one of the most celebrated single pieces of creative work of its decade. It is also, fifteen years later, a case study that marketing students are shown specifically because it did not repeat, and because no campaign the brand produced afterward came close to matching it.
Duolingo's owl, by contrast, has no single video anyone points to as the moment it worked. Zaria Parvez left her original role at Duolingo in 2023 to take on a broader position within the company, and the strategy she began has continued without her under the same team's stewardship, compounding on a base that no longer depends on any one person's individual instinct for what the internet finds funny in a given week.
Franklin's bequest, similarly, produced no notable year on its own. It produced two centuries, and then a number that made two centuries visible all at once.
The real difference was never the size of the moment. It was whether anything was built to be still standing there the following year, ready to receive whatever came next.
So, distribution isn't just reach. It's accumulated trust. Every newsletter subscriber, podcast listener, YouTube subscriber, and returning customer is another deposit into the same account.
Engine
If distribution compounds the way capital does, a few things follow for anyone building something today.
The first is where the audience actually lives. Compound growth requires a base that persists between publishing events: a following, a list, a community that isn't rented from a platform that can reset the relationship at any time.
Without that persistence, every release is functionally Old Spice's ad: excellent on its own, with nowhere to deposit the gain.
The second is what gets measured. A single campaign is usually judged by its own numbers in isolation. A compounding system should be judged by its trajectory instead: is the base growing, is the returning audience share increasing, is each release requiring less cold outreach than the one before it.
The third is what gets funded consistently rather than occasionally. A compound curve only works if the base keeps receiving deposits. An audience that stops hearing from a company starts forgetting it, the same way an account that stops receiving deposits stops growing.
The founders who treat distribution as a sustained practice rather than a periodic campaign are the only ones in a position to experience the upward bend in the curve, because they're the only ones who kept the base intact long enough to reach it.
