The Hewlett-Packard Company (nyse: HPQ), commonly referred to as HP, is a technology corporation headquartered in Palo Alto, California, United States. HP is the largest technology company in the world and operates in nearly every country. HP specializes in developing and manufacturing computing, storage, and networking hardware, software and services. Major product lines include personal computing devices, enterprise servers, related storage devices, as well as a diverse range of printers and other imaging products. Other product lines, including electronic test equipment and systems, medical electronic equipment, solid state components and instrumentation for chemical analysis were spun off as Agilent Technologies in 1999.

HP markets its products to households, small to medium size businesses and enterprises both directly, via online distribution, consumer-electronics and office-supply retailers, software partners and major technology vendors.

HP posted US $91.7 billion in annual revenue in 2006 compared to US$91.4 billion for IBM, making it the world's largest technology vendor in terms of sales. In 2007 the revenue was $104 billion, making HP the first IT company in history to report revenues exceeding $100 billion.

HP is the largest worldwide seller of personal computers, surpassing rival Dell, according to market research firms Gartner and IDC reported in January 2008; the gap between HP and Dell widened substantially at the end of 2007, with HP taking a near 3.9% market share lead. HP is also the 5th largest software company in the world. It is one of the only American PC-focused computer companies publicly traded under the New York Stock Exchange.

Founding

William (Bill) Hewlett and David (Dave) Packard both graduated in electrical engineering from Stanford University in 1935. The company originated in a garage in nearby Palo Alto during a fellowship they had with a past professor, Frederick Terman at Stanford during the Great Depression. Terman was considered a mentor to them in forming Hewlett-Packard.

The partnership was formalized in 1939 with an investment of US$538. Hewlett and Packard tossed a coin to decide whether the company they founded would be called Hewlett-Packard or Packard-Hewlett. Packard won the coin toss but named their electronics manufacturing enterprise the "Hewlett-Packard Company". HP incorporated on August 18, 1947, and went public on November 6, 1957.

Of the many projects they worked on, their very first financially successful product was a precision audio oscillator, the Model HP200A. Their innovation was the use of a small light bulb as a temperature dependent resistor in a critical portion of the circuit. This allowed them to sell the Model 200A for $54.40 when competitors were selling less stable oscillators for over $200. The Model 200 series of generators continued until at least 1972 as the 200AB, still tube-based but improved in design through the years. At 33 years, it was perhaps the longest-selling basic electronic design of all time.
