San Francisco, December 9th, 1968: [[We see a figure talking into a headset. It's a fair assumption that it's Douglas Engelbart.]] Douglas: ... We generated video signals with a cathode ray tube... We have a pointing device we call a "mouse"... I can "copy" text... ... and we have powerful join file editing... underneath the file here we can exchange "direct messages"... [[Douglas continues to narrate. Some music is playing.]] Douglas: ... Users can share files... ... files which can encode audio samples, using our "masking codecs"... The file you're hearing now is one of my own compositions... Music: I heard there was a secret chord [[Douglas continues to narrate.]] Douglas: ... And you can superimpose text on the picture of the cat, like so... This cat is saying "YOLO", which stands for "You Only Live Once"... ...Just a little acronym we thought up... {{Title text: Actual quote from The Demo: '... an advantage of being online is that it keeps track of who you are and what you’re doing all the time ...'}}
