Xerox PARC is 40
The birthplace of Smalltalk (and a ton of other innovations in software and hardware) turned 40:
PARC researchers devised the world's first WYSIWYG editor, the GUI, bitmapped display object-oriented programming methodology, and, yes, the first commercial mouse, all of which were quickly rolled into the Alto workstation - a recognizable modern PC. PARC's boffins also gave us Ethernet and laser printers.
