This episode explores the hidden histories behind planned obsolescence, examining how manufacturers have deliberately shortened product lifespans and shaped consumer desires. The guest traces two distinct stories: the clandestine Phoebus lightbulb cartel of the 1920s that conspired to reduce bulb life to one thousand hours, and Alfred P. Sloan's revolutionary marketing strategy at General Motors that introduced annual styling changes and color variations to drive psychological obsolescence. Together, these histories reveal how the consumer economy transitioned from physical breakage behind closed doors to internal psychological urges that compel buyers to continually replace functioning goods.
