Books, sites, and articles for alumni and friends on the history of HP and many predecessor companies.

On Nov 1, 2015, the legal name of the Hewlett-Packard Company was changed to HP Inc. and a new, completely separate company -- Hewlett Packard Enterprise (no hyphen; singular; green-rectangle logo) -- was spun out. Portions of HPE were later spun out into DXC and Micro Focus, which have spun out other separate companies. Details: HP Breakup  (Note: HP Labs is part of HP Inc. -- but Hewlett Packard Labs is part of Hewlett Packard Enterprise.)

HP Breakup Timeline shows each event as HP spawned Agilent, Keysight, Hewlett Packard Enterprise, HPInc, DXC Technology, Micro Focus, Perspecta... Each is a completely separate company. hpalumni.org/hptimeline
