Did you ever look down at your mouse while completing a computer task and wonder: where did you come from and when were you created? Well if you did (!) - this day back in 1981 saw the first commercially available personal computer mouse packaged with the Xerox Star Workstation.
While this was the first commercially available mouse, it was not the first mouse. The first mouse was developed in 1964 by Douglas Englebart at the Stanford Research Institute. That mouse was made out of a block of wood with two directional wheels on the bottom to control the cursor. The original mouse even had the cord coming out of the bottom - just like a mouse!
