History
The first documented radial menu is attributed to a system called PIXIE in 1969. Some universities explored alternative visual layouts.
In 1986, Mike Gallaher and Don Hopkins together arrived independently to the concept of a context menu based on the angle to the origin where the exact angle and radius could be passed as parameters to a command, or the radius could be used to trigger a submenu.
The first performance comparison to linear menus was performed at 1988 showing an increase in performance of 15% less time and a reduction of selection errors.

Famous quotes containing the word history:
“The history of the genesis or the old mythology repeats itself in the experience of every child. He too is a demon or god thrown into a particular chaos, where he strives ever to lead things from disorder into order.”
—Ralph Waldo Emerson (1803–1882)
“To care for the quarrels of the past, to identify oneself passionately with a cause that became, politically speaking, a losing cause with the birth of the modern world, is to experience a kind of straining against reality, a rebellious nonconformity that, again, is rare in America, where children are instructed in the virtues of the system they live under, as though history had achieved a happy ending in American civics.”
—Mary McCarthy (1912–1989)
“What would we not give for some great poem to read now, which would be in harmony with the scenery,—for if men read aright, methinks they would never read anything but poems. No history nor philosophy can supply their place.”
—Henry David Thoreau (1817–1862)
