The term "Owned" was originally conjured circa 1986 by a small Canadian Apple II user's group in Langley, BC. Primary usage was similar to current internet vernacular, but was usually restricted to computer hardware and not gaming.
Use was slightly adapted to indicate superiority over another person. Or to declare that said person is merely chattel.
Man, the Apple so owns(owned) the C64!
I *own* people like you!
