Planned obsolescence is the practice of designing products with artificially short useful lives so that customers have to buy replacements sooner. The term was coined in 1954 by industrial designer Brooks Stevens at an advertising conference in Minneapolis, where he described it as “instilling in the buyer the desire to own something a little newer, a little better, a little sooner than is necessary.” What started as a marketing philosophy has since evolved into a set of engineering and software strategies embedded in everything from lightbulbs to smartphones.
How It Actually Works
Planned obsolescence takes several distinct forms, and most modern products use more than one at a time.
Contrived durability is the most straightforward version. A product is built with components that are weaker than they need to be, or with parts that can’t be replaced. Think of a pair of wireless earbuds with a sealed battery: once the battery degrades after a couple of years, the entire product becomes trash. The manufacturer could have made the battery swappable, but chose not to.
Systemic obsolescence works through software rather than hardware. When an operating system stops supporting older devices, those devices lose access to new apps, security updates, and sometimes core functionality. The hardware still works, but the software ecosystem moves on without it.
Perceived obsolescence is subtler. It’s the gap between what you already own and what’s currently on the market. Researchers studying this phenomenon identified five dimensions that drive it: aesthetic changes (your product looks dated), social pressure (everyone around you has the newer version), technological improvements (even minor ones), commercial marketing (new launches that frame your product as old), and environmental messaging (newer products marketed as greener). All five dimensions were shown to increase the intention to replace a product that still works perfectly well.
The Lightbulb That Started It All
The most famous example predates the term itself. In the early 1920s, the world’s major lightbulb manufacturers formed a secret cartel called Phoebus. At the time, a standard household bulb lasted between 1,500 and 2,000 hours. By 1925, the cartel had standardized bulb life at just 1,000 hours. This wasn’t a side effect of cost-cutting. As IEEE Spectrum documented, the cartel invested considerable technical effort into engineering a shorter-lived bulb. They had to make it worse on purpose, which took real work.
The Phoebus cartel is often treated as a quirky historical footnote, but it established a template. If companies in a market collectively shorten product life, no single competitor suffers because consumers have nowhere else to turn.
Why Companies Do It
The economic logic is simple. Research from Stanford’s Graduate School of Business frames planned obsolescence as “the production of goods with uneconomically short useful lives so that customers will have to make repeat purchases.” A company with market power generally benefits from shorter product lifespans because each replacement sale generates new revenue. When a product lasts too long, the manufacturer eventually runs out of new customers and has to wait for the existing ones to come back.
This creates a cycle. Shorter lifespans mean more frequent purchases, which fund more product development, which generates more marketing, which accelerates the feeling that what you own is outdated. Companies face pressure to continuously innovate not necessarily because customers need new features, but because growth in revenue depends on it. The result is a linear economy: take resources, make a product, dispose of it, repeat.
Smartphones as a Case Study
Software support timelines are one of the clearest windows into how obsolescence is built into modern products. When a phone stops receiving operating system updates, it gradually becomes incompatible with newer apps and vulnerable to security threats. The phone still turns on, but its useful life is effectively over.
How long you get depends heavily on which brand you buy. Apple commits to a minimum of five years of software support, but most iPhones receive at least six years of updates regardless of price tier. Google set a new benchmark with its Pixel 8 series, promising seven years of both operating system upgrades and security patches, though its older models only got three years of upgrades and five years of patches. Samsung’s latest flagship phones now match Google at seven years, while most of its other recent phones get four years of upgrades and five years of security patches. Budget models from Samsung sometimes drop to three years.
These timelines have improved dramatically in just a few years. Before 2021, three years was considered generous for an Android phone. The shift happened partly because of competitive pressure and partly because regulators started paying attention. But even seven years is a fraction of how long the physical hardware could function with continued software support.
The Environmental Cost
Shorter product lives generate more waste, and the numbers are staggering. In 2022, the world produced a record 62 million tonnes of electronic waste. Less than a quarter of it, just 22.3%, was properly collected and recycled. The rest ended up in landfills, informal recycling operations, or simply lost track of entirely. Global e-waste generation is climbing by 2.6 million tonnes every year, rising five times faster than documented recycling rates.
Electronics contain valuable and sometimes hazardous materials: rare earth metals, lithium, lead, mercury. When a phone or laptop is discarded two or three years before its hardware fails, all of those materials are wasted prematurely. The environmental cost isn’t just the device you throw away. It includes the mining, manufacturing, and shipping required to produce its replacement.
What Regulators Are Doing About It
The European Union has passed the most aggressive legislation to date. Its Directive on the repair of goods, which member states must implement by July 31, 2026, targets planned obsolescence directly. Manufacturers of products like refrigerators and smartphones will be required to repair those products within a reasonable time and at a reasonable price. They must provide access to spare parts at reasonable prices as well.
The directive goes further than just parts availability. It explicitly prohibits manufacturers from using contractual clauses, hardware designs, or software techniques that prevent repair, unless there’s a legitimate and objective reason. That last clause is significant because it closes the loophole companies have used for years: claiming that sealed designs or locked-down software exist for “quality” or “safety” reasons when they primarily exist to push consumers toward buying new.
Several U.S. states have passed their own right-to-repair laws, though they vary widely in scope. France has gone a step further with a “repairability index” that scores products on how easy they are to fix, displayed right on the packaging at the point of sale.
How to Recognize It
Not every product failure is planned obsolescence. Parts wear out, technology genuinely improves, and sometimes a new product really is worth upgrading to. But there are patterns worth watching for. If a product uses proprietary screws or adhesives that make opening it nearly impossible, that’s a design choice, not a necessity. If a battery is glued in rather than held by clips or screws, the manufacturer has decided your product has an expiration date tied to battery chemistry. If software updates slow down your device or remove features that previously worked, that’s systemic obsolescence in action.
The most reliable defense is also the simplest: before buying, check how long the manufacturer commits to software support, whether replacement parts are available, and whether independent repair shops can service the product. These details, once buried in technical documentation, are increasingly easy to find as consumer awareness grows and regulation forces transparency.
