XEROX Corporation
xerox
    A US company, founded in 1906, specialising in document
   related technology and services including photocopiers, printers
   and office software.  Xerox's acquisition of Affiliated Computer
   Services added business process and document management to their
   product range.  In 2013 they have 140,000 employees.
   Their research centre, XEROX PARC, prototyped several
   revolutionary advances in computing, which the company failed to
   exploit, including the WIMP desktop metaphor and XEROX Network
   Services.
