>>In December 1968, engineer and inventor Douglas C. Engelbart and a team of more than a dozen engineers and staff from the Augmented Human Intellect Research Center (AHIRC) gave a demonstration at San Francisco’s Civic Center Auditorium to show off what they called the oN-Line System (NLS). The demo, which lasted for about an hour and a half, became known as “The Mother of All Demos” because for many of the 1,000 computer technology professionals in the audience, it was the first time they saw personal computers used interactively, rather than crunching numbers via punch cards.<<

cant add much more to that other then this is probably one of the most important demo's ever in the history of computing and one of the reasons why we have computers in its current form

its all there and as they say the rest is history

Reading over it now

It's crazy to think how for this technology has come. It's like when I think about how there was no internet growing up, and a time when I wrote my papers on an electric typewriter. And a time when I'd never ever would have thought is be discussing random nonsense with people around the globe on a video game forum.

I thought this was going to be a thread about Grimoire.

what i think is crazier is how fully formed this demo and the xerox star from parc ( 1973 ) already were http://en.wikipedia.org/wiki/Xerox_Alto
it just took 16\11 years for it all to become "affordable" enough for the home user with the macintosh in 1984
the alto almost did everything the macintosh did

and its pretty much thanks to parc that we are even talking to each other here at all

but this demo is where it all started demo not demon ;p
