History of Radio

People listen in their cars and living rooms every day, but few are familiar with the place where the radio is actually coming from. The radio, as we know it today owes its existence to two previous inventions, the telegraph and the telephone. In the 1860s, the existence of radio waves was predicted by James Clerk Maxwell, but most likely never have imagined the technology that could lead a.

In 1895, Italian inventor Guglielmo Marconi sent and received the first radio signal, which demonstrates the possibility of radio communication. Sent the first wireless signal across the English Channel in 1899 and after two years have passed, received a single letter S that was broadcast from England. This event marked the first time a transatlantic telegraph was successful.

When radio was first used, not to transmit the audio as it does today, but signs of dots and dashes like Morse code. There are two accounts of the first human voice is transmitted by radio, and it is clear that it is authentic. Nathan B. Stubblefield broadcast Hello Rainey in 1892 in Murray, Kentucky. The other is attributed to Reginald A. Fessenden, who is said to have issued a test program of music and talk in 1906, which could be tried within a few hundred miles.

True broadcasting, as it is thought of today, began in 1915 when the speech was broadcast from New York to California and from Virginia Paris. The first daily radio programs began in 1920 with the return of the Harding-Cox election broadcast. Only seven years later, the European commercial radiotelephone with North America and then three years later, South America.

Today, radio has become a common form of technology, most people did not notice it. However, the ancestors of radio technology probably had no idea that one day the radio would be normal in any car or even listen to radio stations via Internet. Because of his work and research, we all have access to music and information virtually anywhere you go.
