In February 1900, you could buy a camera for a dollar. It was a small cardboard box called the Brownie, simple enough for a child, and it sold more than 150,000 units in its first year.1 A dollar was not the company giving anything away. It was bait. The Brownie existed for one reason, documented in how it was conceived and marketed: to sell Kodak roll film.11 The camera was a one-time sale. The film was a habit - bought again, and again, and again, for the rest of a customer's life.

The story usually told is that Gillette invented the razor-and-blades model and Kodak copied it. Strike that. Eastman's photographic business was running on cheap hardware and recurring consumable sales from 1888, and Eastman Kodak Company was incorporated in 18922 - years before Gillette founded his razor company in 1901.9 The marketing label came later. The strategy was Kodak's, and it predates the model's most famous eponym.11

The camera was the price of admission, not the product

George Eastman understood something his hardware competitors didn't: a camera is bought once, but a photograph is bought every time. His 1888 box camera shipped at $25 with film inside, and it was engineered from the start to drive profit from high-margin film rolls and processing - a dynamic Eastman recognized explicitly as a way to expand the user base.6 Sell the device near cost, and every device becomes a meter that runs for decades. The whole company is built around a single causal loop: the cheaper the camera, the larger the installed base; the larger the base, the more film, paper, and processing chemicals flow back at fat margins.8 The hardware doesn't make the money. The hardware creates the customer who makes the money.

Eastman recognized that film would return more profit than cameras and focused on controlling the film market; this razor-and-blades model of sales would change little for several decades.2
From the historical record of Eastman KodakOn Eastman's deliberate strategy after the 1892 incorporation

The thesis, stated plainly: Kodak was never a camera company that happened to sell film. It was a film company that gave people a cheap reason to keep buying film - and it engineered that loop on purpose, before anyone had a name for it.

How thin hardware compounds into a near-monopoly

Run that loop for seventy-five years and the numbers stop looking like a business and start looking like a tollbooth. By 1976 Kodak controlled 90% of film sales and 85% of camera sales in the United States.3 That asymmetry is the whole tell. Why was the film share higher than the camera share? Because cameras were a battlefield - rivals could and did sell competing bodies. But once a customer was in the Kodak habit, the recurring blade-purchase belonged to Kodak almost by default. The lock-in was less often a technical one than a habitual one; brand loyalty and a yellow-box processing infrastructure on every drugstore counter kept customers in the ecosystem - softer than an ink cartridge welded to a printer, but at that scale, just as binding.

90%
of U.S. film sales were Kodak's by 1976 - a higher share than its 85% of camera sales, because the blade, not the razor, was the prize3

Why digital didn't undercut the model - it deleted it

Here is where the popular Kodak story gets the failure exactly wrong. A razor-and-blades business is famously robust against price wars on blades; you can survive a competitor cutting blade prices because the loop still spins. What no such business survives is a world that no longer needs blades at all. Digital photography did not make film cheaper. It made film unnecessary. The recurring purchase - the entire engine of the model - simply ceased to exist. Worse, the hardware logic inverted. In the film era, cheap cameras were a deliberate investment that paid back through consumables. In digital, by 2001 Kodak's cameras were estimated to lose roughly $60 per unit sold, with no film stream waiting downstream to recoup it.4 The cheap-hardware habit, once the smartest move in the company, became a bleed with nothing on the other side.

Chapter 115
Kodak files for bankruptcy with $5.1B in assets against $6.8B in debt.

Kodak held a 27% share of the U.S. digital camera market as late as 19994 - this was never a company that failed to see the technology. It saw it clearly, and even competed in it. The trap was subtler than blindness: the asset that had made Kodak rich was a recurring consumable, and the new world had no consumable to be the toll-keeper of. The company filed for Chapter 11 in January 2012, carrying $6.8 billion in debt against $5.1 billion in assets,5 and emerged in 2013 as a small B2B imaging firm whose 2022 revenue was $1.2 billion at a 14% gross margin.7 The empire built on a dollar camera ended up smaller than the margin it once skimmed from a single year of film.

Isn't this just a company that missed the future?

The fair objection is that this is the standard innovator's-dilemma tale: an incumbent too fat on legacy margins to embrace the disruption. There's truth in it - the film margins — reported by industry observers at around 80% at their peak10 — (treat any specific figure as an attributed estimate rather than an audited one) gave any digital alternative an impossible internal hurdle to clear. But that framing misses what makes Kodak's specific case sharper. The honest counter to the 'they should have gone digital faster' line is this: going digital faster would not have saved the business model, only the brand. The model's profit was structurally tied to a consumable, and digital had none. Kodak could have owned digital cameras outright and still watched its economics collapse, because the thing that made cameras worth selling cheaply - the lifetime of film behind them - was gone. The lesson is not 'don't ignore disruption.' It's that a razor-and-blades fortune is only as durable as the world's need to keep buying blades.

Know whether you sell the razor or the need for blades

Razor-and-blades is the most seductive model in business: cheap hardware, recurring margin, compounding lock-in. But its entire foundation is the assumption that the blade stays necessary. Two questions decide your fate, and most operators only ask the first. One: can a rival undercut my blade? (Survivable - the loop still spins.) Two: can a technology make the blade obsolete? (Fatal - the loop stops.) Kodak spent a century defending against the first question and was destroyed by the second. If your profit lives in a consumable, the threat to watch isn't the cheaper consumable. It's the world deciding it doesn't need a consumable at all.

Kodak's genius was real and it came first: sell the camera near nothing, and own the film forever. For three-quarters of a century it was one of the most beautiful loops in commerce - a dollar of hardware spinning off decades of high-margin habit. It didn't die because someone sold cheaper film. It died because the camera finally needed no film at all. The razor-and-blades model never lost its edge. The world simply stopped needing to shave.
