Many of the things we do with our computers nowadays have been invented by Xerox.
It’s an amazing story, and often recounted - but let me summarize it here.
To be more precise, the story is about Xerox PARC, the Palo Alto Research Center.
Nearly everything that’s crucial for our computers today has either been invented there, or applied there for the first time.
Graphical displays, graphical user interfaces, WYSIWYG, windows, menus, Ethernet, laser printers, object-oriented programming.
These would all go on to be successfully implemented by every single computer company.
Except for Xerox.
