The Great Lightbulb Conspiracy https://spectrum.ieee.org/the-great-lightbulb-conspiracy

> On 23 December 1924, a group of leading international businessmen gathered in Geneva for a meeting that would alter the world for decades to come. Present were top representatives from all the major lightbulb manufacturers, including Germany’s Osram, the Netherlands’ Philips, France’s Compagnie des Lampes, and the United States’ General Electric. As revelers hung Christmas lights elsewhere in the city, the group founded the Phoebus cartel, a supervisory body that would carve up the worldwide incandescent lightbulb market, with each national and regional zone assigned its own manufacturers and production quotas. It was the first cartel in history to enjoy a truly global reach.

Devil's advocate: Incandescent lifetime is inversely related to efficiency, thus Phoebus cartel prevented spread of long-life but inefficient bulbs.

An also should add that color temperature on incandescent lamps play a role on its lifespan, want long lasting lamps? Lower the current (or increase the resistance).
