The Mother of All Demos

The complete video of Doug Englebart's famous live demo of SRI's Online System, the first computer mouse, a graphical interface, file sharing and dynamic file links and even video conferencing from December 1968 is available online here. This demo has become so famous in computer history it's often called "the mother of all demos". It really would have seemed like science fiction in 1968 when most computer users were submitted batch process jobs via punch cards to mainframe computers and waiting hours or days for a print out of their results.
