History of the Radio
|Marconi Radio Receiver|
When Benjamin Franklin discovered that there were negative and positive charges in electricity, the search to use electricity as means for communication was started. Radio signals were sent through the many cables of the telephone network and were used mainly for the military.
Nikola Tesla was the inventor of the model for radio, but only in theory. However, Tesla's invention of transformers and the Tesla coil helped in the production of radios. These were some of the core components used in radios.
|Guglielmo Marconi 1901|
Bose did apply for a patent as the inventor of the radio, in 1901 and was awarded it in 1904. However, Marconi by this time had already received the recognition and patent for being the inventor of the radio.
The first wireless transmission of voice, however, was not made until 1895, when Russian, Aleksander Poppov sent a secret message to a ship on the ocean. This was kept secret and the Russian government only recently has given Poppov this credit.

In 1912, the American airwaves became regulated by the Federal government. All ships had to include a radio and a trained operator. Any amateur radio operators needed to be licensed. As other inventors and businessmen were beginning to see the potential for these amplified radio waves, World War I broke out and the government took over all radio broadcasts and closed down any other radio stations that were not needed.
