Your question is vague, but I'll assume it's not intentional.
If the "this" you are referring to is computer history, it's general knowledge for IT nerds like myself. For a general primer on computing history, try this:
http://www.maxmon.com/history.htm
In a pinch, there's always google.
http://directory.google.com/Top/Computers/History/
It is a popular view amongst historians that the Internet, and specifically, the http protocol (worldwide web) only enjoyed mass consumer acceptance due to the explosion in PC ownership. So ironically if there had been a standardisation in the 60s, it may be likely the only place to find this sort of information would be in hard copy. Most local libraries will have some basic books on computing history.
If by "this" you are asking how I know if there had been government enforced standardisation, there would be no PCs.... I think it becomes self-explanatory once you understand general computing history. If the government had mandated that all cars have 3 wheels, we would have no 4 wheeled cars.
Finally, if by "this" you are asking how Joe knows that personal computing and computing in general has not reached a regulatable plateau in development, that is also self-explanatory given some general knowledge in computing trends. Radically new things come out every few weeks rather than every few years as in the car industry (PDAs, cellphone mergence, handheld computers, wearable computers, new processors, software exploits, software patches, hardware exploits, SPAM, new standards to combat SPAM etc).
