Company InformationHewlett-Packard Company, commonly known as HP, is a very large global corporation headquartered in Palo Alto, California, United States . Its products are concentrated in the fields of computing, printing and digital imaging. It also sells software and services.History and FactsHP was founded in 1939 by Bill Hewlett and Dave Packard, both graduates of Stanford University in 1934, as a manufacturer of testing and measurement instruments. Their first product was a precision audio oscillator, the Model 200A. Their innovation consisted of using a light bulb as a temperature-stabilized resistor in a critical part of the circuit. This allowed them to sell the 200A model for $54.40 while their competitors were selling less stable oscillators for over US$200. One of their first customers was Walt Disney Productions, which purchased eight Model 200B oscillators (at $71.50 each) to test the Fantasound. stereophonic sound system for the film Fantasia.HP is recognized by Wired magazine as the producer of the world's first personal computer, in 1968, the Hewlett-Packard 9100A. HP called it a desktop calculator because, as Bill Hewlett said: "If we had called it a computer, it would have been rejected by our customers' computer gurus because it didn't look like to an IBM. So we decided to call it a calculator and all this nonsense disappeared." The company has gained worldwide respect for a variety of products.
