Back in the 1800's Samuel Morse, an American, invented a unique code of dots and dashes and assigned it to each letter and number to transmit information, hence the name Morse code.
On May 24, 1844 his first transmission from Washington, D.C. to Baltimore was "What has God wrought" and as if by magic, communications over long distances came to be.
Morse Code was used to broadcast to the world the end of both World Wars, it was also used by ships in distress, lighthouses, radio navigation beacons for aircraft, and short wave radio transmissions. Morse code still has its uses especially in times of power outage. Signals get through because they require less broadcasting power to transmit. 
Today is the anniversary of that first Morse code messages sent by Samuel Morse. The paper tape of that original message is on display in the Library of Congress in Washington, D.C.
Thanks to global positioning systems, communications have improved. From smoke signals to a worldwide communication system—I wonder what is next!
