Lightbulb Conspiracy

The Lightbulb Conspiracy documentary that we watch this week was mainly about how the Lightbulb companies used to create Lightbulbs that lasted 1000 hours, but throughout the years these companies developed something called planned obsolesence. This tecnique was used by the Lightbulb companies many years ago and now days is being used by nos of the companies around the world. It also showed an example of a Lightbulb that was in a fire station that had lasted 100 years.
