Alexander Graham Bell entirely utilized the expression "hi" . The principal call he made was to his right hand who was in the bordering room and he said "Come-here. I need to see you."
"Hello" really originated from hola which intended to stop and focus. Alexander Bell wanted to utilize Ähoy"as in the boats those days which co-unexpectedly was misheard by Edison.
In 1877, Edison kept in touch with T.B.A. David, the leader of the Central District and Printing Telegraph Company of Pittsburgh:
Companion David, I don't figure we should require a call chime as Hello! can be heard 10 to 20 feet away.
What you think? Edison - P.S. to begin with cost of sender and recipient to make is just $7.00.
