Subject: The Telephone - A Brief History
By Jason Morris
During the 1870's, two well known inventors both independently
designed devices that could transmit sound along electrical
cables. Those inventors were Alexander Graham Bell and Elisha
Gray. Both devices were registered at the patent office within hours
of each other. There followed a bitter legal battle over the invention
of the telephone, which Bell subsequently won.

Telex certainly should be called the original form of E-Mail. Far from
"dead" on a global basis, UN reports published in the "Brittanica Book
of the Year" indicate there are about three million Telex lines around
the globe. Contrary to the impression international telephone people
like to create, direct, immediate access via Telex still exists to
more of the world's political entities than does telephone. This has
been the case for many years. (Totalitarian governments must like
Telex; they have been known to shut down telephone service, but not
Telex. The suspected reason: It can be monitored with hard copy
easily, and often [has] been, too. Of course, they themselves use it
for military messages.)
