RCA was built from the surplus of GE and Westinghouse.

So I don't think RCA was in any position to sue the General for anything.

Everyone in those days was in the commercial electronics business, small radios and communications and later television.

Other companies such as Rayethon, Murata Erie, Sylvania came along later.

Most of the residents of my small town migrated to Emporium and St. Mary's PA during WW II to get jobs in the small tube manufacturer plants.
Brookville PA, along with Dubois and Bradford also had tube plants.

Most of those plants shifted production to Powder Metals after the war.
Some upgraded their plants to produce light bulbs and other electronics.
