Source: Unknown.Bell's First TelephoneAlexander Graham Bell's interest in the education of deaf individuals
led him to develop the microphone and in 1876, what he referred as an
"electrical speech machine", better known today as a telephone. By 1878, Bell had set up a telephone exchange in New Haven, Connecticut.
By 1884, long distance connections had been made between Boston, Massachusetts
and New York City. Bell imagined great uses for his telephone but he
never imagined that telephone lines could be used for transmitting video
images. Since Alexander Graham Bell's death in 1922, the telecommunication
industry has undergone an amazing revolution. This revolution has gotten
to the point that one's ability to access information relies upon telecommunications
technology. Bell's "electrical speech machine" paved the way for the
information superhighway.
