On December 9, 1968, Stanford Research Institute scientist Douglas Engelbart demonstrated his unique invention – the computer mouse – for the first time
in public.

The name “mouse” derives from the resemblance of early models (which had
a cord attached to the rear part of the device, suggesting the idea of a tail)
to the common mouse.

The first marketed integrated mouse – shipped as a part of a computer -
came with the Xerox 8010 Star Information System in 1981.

Today, it's hard to imagine using a desktop or laptop computer without a mouse
(or one of its latter-day substitutes such as the touchpad). A mouse now comes
with most computers and many other varieties can be bought separately.

In celebration of this anniversary, Brown gives you a mighty mouse to enjoy -
just don’t ask to see the keyboard!
