Built to Break

Products with a design deadline

If advertising manufactures the desire to buy, planned obsolescence manufactures the need to buy again. This chapter covers two genuinely different phenomena that get lumped together under that one phrase — one a documented, contested cartel; the other an openly acknowledged, uncontested business strategy — and the difference between them matters.

The lightbulb cartel

In January 1925, major lightbulb manufacturers — including Osram, Philips, the Compagnie des Lampes, and General Electric (participating indirectly through an overseas subsidiary, reportedly to limit its US antitrust exposure) — formally incorporated an international cartel in Geneva, dividing world markets into territories and quotas. The cartel also enforced a standardized bulb lifespan of roughly 1,000 hours, backed by a real enforcement mechanism: a central testing laboratory in Switzerland, and a documented schedule of fines levied against manufacturers whose bulbs lasted too long, alongside separate fines for exceeding sales quotas. This isn't speculative history — it's built on archival correspondence and meeting minutes a media historian found in Osram's own corporate archive decades later, and it's corroborated by a real 1949 US antitrust finding against General Electric that touched on the same international lamp-cartel conduct.¹

Where the popular retelling overreaches: bulbs before the cartel commonly ran 1,500 to 2,000 hours, occasionally as long as 2,500 — not a single clean number, and the popular "2,500 down to 1,000" framing compresses a range into a soundbite that sounds more dramatic than the underlying record supports. More importantly, the "purely engineered sabotage for profit" framing skips over a genuine, contested engineering trade-off: a lightbulb filament run hotter produces more light per watt but burns out faster, and a cooler-run filament lasts longer but wastes more energy as heat instead of light. The cartel's own defenders at the time invoked exactly this trade-off. Whether settling specifically on 1,000 hours reflected a legitimate optimization of that trade-off, or whether the fine structure (penalizing longer-lived bulbs specifically) shows the real motive was suppressing durability for profit, is a live disagreement in the historical record — not a settled question, whatever a given retelling implies.²

The pamphlet that gave the idea its name

In 1932, a New York real estate broker named Bernard London self-published a pamphlet titled Ending the Depression Through Planned Obsolescence, registering it with the Library of Congress.³ London's diagnosis of the Depression was that consumers were keeping cars, tires, radios, and clothing in use far longer than manufacturers expected, starving industrial demand. His proposed fix, genuinely radical: the government would assign every consumer product a legally mandated expiration date, after which the item would become legally "dead" and would have to be turned in or destroyed — forcing replacement purchases on a schedule, as deliberate economic stimulus. It was never adopted, and London remained an obscure figure, but he's credibly the source of the term "planned obsolescence" itself, coined in earnest as public policy rather than as a critique of industry.

Detroit's version — and why it's not the same claim

The clearest, least contested version of planned obsolescence isn't a secret cartel at all — it's a strategy General Motors adopted openly under president Alfred Sloan starting in the mid-1920s, in response to a market where most households who wanted a car already had one. Rather than compete only on mechanical improvement, GM introduced annual model-year styling changes, formalizing the approach in 1927 by creating the industry's first dedicated styling department (initially called the Art and Colour Section, led by designer Harley Earl). Sloan himself named the strategy "dynamic obsolescence" and discussed it candidly in his own memoir — there's no hidden-archive reveal here, no antitrust case, no dispute about whether it happened or why.⁴ It's well-documented mainstream business history, aimed at aesthetic and psychological obsolescence — the desire for the new look — not at physically degrading a car's durability or safety. Treating this and the lightbulb cartel as the same kind of claim, at the same evidentiary weight, overstates the more contested one and undersells how openly the other was always discussed.

Where Plenee fits

Depreciation is where this history lands in practical terms: every category built on a replacement cycle — cars, phones, fashion, appliances — depreciates on a curve partly shaped by decades of deliberate design decisions about how long a product should stay desirable or functional. Knowing that the replacement cycle was, at least in part, engineered rather than purely organic wear doesn't change the arithmetic of buying the three-year-old version of anything instead of the new one — it just explains why that arithmetic works as well as it does.
