Planned obsolescence
Etymology
The phrase was popularized by Bernard London’s 1932 pamphlet proposing obsolescence as a way out of the Depression, and later by industrial designer Brooks Stevens in the 1950s, who framed it as instilling the desire to own something newer sooner. Journalist Vance Packard spread the critique widely in his 1960 book The Waste Makers. "Obsolescence" comes from the Latin obsolescere, to fall into disuse.
noun phrase · /PLAND ob-suh-LES-ens/
The deliberate design of products to wear out, break, or feel outdated so buyers replace them sooner.
What it names
It gives a name to the suspicion that your phone slows down, your appliance dies just past warranty, and last year’s model is suddenly unsupported by design, not by accident.
Example
When the manufacturer stopped issuing security updates after three years, it looked less like a technical limit than planned obsolescence.
Related idea
Planned obsolescence engineers the product to fail or age out; the right to repair movement is the countermove, pushing for hardware and parts that owners can actually fix and keep.
