context_page_description: Xerox Holdings Corporation is an American corporation that sells print and digital document products and services in more than 160 countries. Xerox is headquartered in Norwalk, Connecticut, though its largest population of employees is based around Rochester, New York, the area in which the company was founded. The company purchased Affiliated Computer Services for $6.4 billion in early 2010. As a large developed company, it is consistently placed in the list of Fortune 500 companies.
  On December 31, 2016, Xerox separated its business process service operations, essentially those operations acquired with the purchase of Affiliated Computer Services, into a new publicly traded company, Conduent. Xerox focuses on its document technology and document outsourcing business, and continues to trade on the NYSE.
  Researchers at Xerox and its Palo Alto Research Center invented several important elements of personal computing, such as the desktop metaphor GUI, the computer mouse and desktop computing. The concepts were adopted by Apple and later Microsoft.
context_section_description: In 1970, under company president C. Peter McColough, Xerox opened the Xerox Palo Alto Research Center, known as Xerox PARC. The facility developed many modern computing technologies such as the graphical user interface (GUI), laser printing, WYSIWYG text editors and Ethernet. From these inventions, Xerox PARC created the Xerox Alto in 1973, a small minicomputer similar to a modern workstation or personal computer. This machine can be considered the first true Personal Computer, given its versatile combination of a cathode-ray-type screen, mouse-type pointing device, and a QWERTY-type alphanumeric keyboard. But the Alto was never commercially sold, as Xerox itself could not see the sales potential of it. It was, however, installed in Xerox's own offices, worldwide and those of the US Government and military, who could see the potential. Within these sites the individual workstations were connected together by Xerox's own unique LAN, The Ethernet. Data was sent around this system of heavy, yellow, low loss coaxial cable using the packet data system. In addition, PARC also developed one of the earliest internetworking protocol suites, the PARC Universal Packet (PUP).
  In 1979, Steve Jobs made a deal with Xerox's venture capital division: He would let them invest $1 million in exchange for a look at the technology they were working on. Jobs and the others saw the commercial potential of the WIMP (Window, Icon, Menu, and Pointing device) system and redirected development of the Apple Lisa to incorporate these technologies. Jobs is quoted as saying, "They just had no idea what they had." In 1980, Jobs invited several key PARC researchers to join his company so that they could fully develop and implement their ideas.
  In 1981, Xerox released a system similar to the Alto, the Xerox Star. It was the first commercial system to incorporate technologies that have subsequently become commonplace in personal computers, such as a bitmapped display, window-based GUI, mouse, Ethernet networking, file servers, print servers and e-mail. The Xerox Star and its successor the Xerox Daybreak, despite their technological breakthroughs, did not sell well due to its high price, costing $16,000 per unit. A typical Xerox Star-based office, complete with network and printers, would have cost $100,000.
  In the mid-1980s, Apple considered buying Xerox; however, a deal was never reached. Apple instead bought rights to the Alto GUI and adapted it into a more affordable personal computer, aimed towards the business and education markets. The Apple Macintosh was released in 1984, and was the first personal computer to popularize the GUI and mouse among the public.
  In 2002, PARC was spun off into an independent wholly owned subsidiary of Xerox.
