Just like a song you haven't heard in forever brings back all sorts of memories and feelings, seeing video of computers back in the day brings back visions of the first Doom and slowly loading pictures.  If you were at a computer using age in the 90's you may remember how incredibly different it was to be online.  This video is a brief look at how it might have worked had it been invented in the 90s.  I don't think it would have taken off quite as quickly.
