The term "HP" stands for Hewlett-Packard, an electronics company. Hewlett-Packard was originally founded by William Hewlett and David Packard in 1939. It is still in business today and is well-known worldwide.
The first product release of the Hewlett-Packard company was an audio oscillator, an instrument invented by William Hewlett and used to test sound equipment. The duo's first major customer was the Walt Disney Company, who place a large order in 1940. The company comes from humble beginnings, starting off in Hewlett's garage in Palo Alto, California. The firm is now known worldwide as a manufacturer of quality computer and electronic equipment.
