Telephone, television, radio, and
telegraph all help people
communicate
with
each other. Because of these
devices, ideas and
news of events
spread quickly all
over the world. For
example,
within seconds, people can
know the results of an
election in
another country. An international
football match comes into the homes
of
everyone with a television of a disaster such as
an
earthquake or a
flood can
bring help from distant countries within
hours, help is on the way. Because of
modern technology like the
satellites
that travel around the world, information travels

War of 1812 between England and the

peace took
six weeks to reach America.
During these six weeks, the large and
serious Battle of New Orleans was
fought. Many people lost their
lives
after a peace treaty had been would not have died
if news had come in the
past,communication took much time
than
it does now.
There was a good reason why the world
seemed so much larger than
it does
today.
