(in fact, KDKA's first general manager, whose name I've forgotten, is
considered to have coined the word "broadcast")

That would be a neat trick, seeing as how one cannot coin a word that
already
exists. The term "broadcast" came from agriculture.

Coining new meanings from older words happens all the time. Consider "Mace",
originally meaning a club (weapon), used as a trademark for a chemical that
repels attackers, and in danger of becoming a generic word.
