It all started with the radio waves From their prediction in 1860 it took science people 26 years to even prove that the rapid variations of electric current could be projected into space in the form of radio waves similar to those of light and heat. In 1866 an American dentist was able to make a meter connected to one kite cause another one to move, marking the first known instance of wireless aerial communication. Wireless signals proved effective in communication for rescue work when a sea disaster occurred.

A number of ocean liners installed wireless equipment. In 1899 the United States Army established wireless communications with a lightship off Fire Island, New York. Two years later the Navy adopted a wireless system. Up to then, the Navy had been using visual signalling and homing pigeons for communication.In the early 1900s, the great requirement for further development of radio was an efficient and delicate detector of electromagnetic radiation.

Lee De Forest provided that detector. It made it possible to amplify the radio frequency signal picked up by the antenna before application to the receiver detector; thus, much weaker signals could be utilized than had previously been possible. De Forest was also the person who first used the word "radio". The result of Lee DeForest's work was the invention of amplitude-modulated or AM radio that allowed for a multitude of radio stations. The earlier spark-gap transmitters did not allow for this.
