Hey, just so you know ... this post is now about 16 years and 10 months old. Please keep that in mind as it very well may contain broken links and/or outdated information.The beloved computer mouse turned 40 earlier this week. Check out some of these great video clips from Doug Englebart’s 1968 demo at Stanford. Jump right to clip #12 to see Doug demo the mouse and explain how it works. Did you know they used to call the cursor (or pointer) the bug? Really cool, amazing stuff.
