The tattered history of OOP
OOP has been a mixed bag, but I say this only because like with the PC, the creative vision of OOP was lost. What follows is largely based on Alan Kay's presentation called "The Computer Revolution Hasn't Happened Yet" that he gave at the 1997 OOPSLA conference (available at Google Video), and a paper he wrote many years ago, available online, called "The Early History of Smalltalk", among other sources.
