Radio/Audio broadcasting [1919 to 1950s]

Crystal set was the most common type of receiver before vacuum tubes, although some old radios used some type of amplification through electric current. Inventions of the triode amplifier, motor-generator, detector etc enabled audio radio. The use of amplitude modulation make more than one station can simultaneously send signals.

During the middle of 1920s, amplifying vacuum revolutionized radio transmitters and receivers. John Fleming developed an earlier tube known as an oscillation valve. The Dutch engineer Hanso Schotanus  made the first regular wireless broadcast. Hanso Schotanus broadcast his popular program four nights per week until 1924.

Invention of radio

James clerk Maxwell proved mathematically that electromagnetic waves could propagate through free space. Heinrich Hertz demonstrated propagation of radio.

Nikola Tesla experimentally showed the transmission and radiation of radio frequency energy in 1892 and 1893 proposing that it might be used for the telecommunication.

In 1895, Marconi built a wireless system that capable of transmitting signals at long distances.  From his experiments, the phenomenon that transmission range is proportional to the square of antenna height is known as “Marconi’s law”. This formula represents a physical law that radio devices use.

Guglielmo Marconi demonstrated application of radio in commercial, military and marine communications and started a company for the development of radio communication.

In 1901, Marconi conducted the first successful transatlantic experimental radio communications. In 1904, The U.S. Patent Office reversed its decision, awarding Marconi a patent for the invention of radio and  Marconi established the first commercial transatlantic radio communications service, between Clifton  Ireland and Glace Bay.
