A person often wishes to share an idea with someone else. People always are eager to get news of interesting happenings. Passing along ideas and news is called communication.
Making gestures and talking were probably the first ways of communicating. Later men learned to draw pictures, to write, and much later, to print. They learned to send signals with drums and smoke and mirrors. They worked out ways for messengers to travel fast from place to place.
During the past 100 years many new ways of communicating have been invented. Today we have the telegraph, the telephone, and the radio. We have message cables which cross oceans. We have moving pictures, filmstrips and television. Our newest means of communication is internet.
