What’s the history behind that?
I stand corrected. Actually Jobs stole it from Xerox and Gates from Jobs. There is a lot of controversy regarding the trail but the time line is clear.

Also there is a documentary film on this subject that is the best source of undisputed facts, but I can’t remember the title. I will look for it.
