No, they were invented at the University of Illinois, produced
by Owens-Illinois, and originally implemented as computer
terminals by Magnavox. They were in production by 1972.

Fujitsu bought rights to some of the patents and produced their
own plasma panels for computer and defense use. IBM did
too -- and later sold their plasma panel line to Photonics.

Sony didn't enter the picture until more than 20 years later.
