Did you know this ?

How did '"HELLO"' come to be
used as a greeting over the
phone?::

The first word used to answer the phone was
the nautical greeting 'ahoy' because the first
regular phone system was in the maritime
state of Connecticut. Alexander Graham Bell,
the inventor, answered with the Gaelic 'hoy'.
But it was Thomas Edison's greeting of
'hello', an exclamation of surprise dating
back to the Middle Ages, that caught on, and
so we answer the telephone today with,
'Hello?' Another theory is that after
inventing the telephone, he rang his
girlfriend whose name was 'Hello', thus the
first word said by him on telephone became
a greeting. Before 'Hello' became popular,
telephone operators started conversations
with, "Are you there?
