CD2:27 How do you communicate with people far away? Do you
call them on your cell phone? Do you email them? How
did people communicate in the past?
The oldest form of communication is the smoke signal.
People in Ancient China used the smoke signal in
1
800
BCE. They sent messages from tower to tower on the
Great Wall of China to signal danger or call for help.
People began writing letters in 600 BCE. But they couldn’t
send them in the mail. Messengers had to carry the letters
and give them to people. They took a long time to arrive!
In
1
844, Samuel Morse sent the first telegram. People
could send telegrams more quickly than letters. But they
still couldn’t talk to each other across long distances.
Alexander Graham Bell invented the telephone in
1
876. Now people could talk, but they had to be near a
telephone! There weren’t any cell phones until
19
73.
Tim Berners-Lee invented the World Wide Web in

and easily with the Internet.
