The History of the Radio
The radio owes its development to the inventions of the Telegraph, and the Telephone. It all started with the discovery of radio waves, or waves that can transport music, speech, pictures, and much more. These waves are used in many modern inventions today.
The Growth of Radio Radio telegraphy was the sending of a message by using Morse code, or a series of dots and dashes. At this time, transmitters were called spark-gap machines; it was developed mainly developed for ship to shore communication. This was far from the public radio broadcasting we know today. Improving the Radio The radio improved mostly when it was overseas. Lee Deforest created space telegraphy. He made it possible to amplify the radio frequency. He was also the person who first called the radio, the radio. He also made it so the radio could have several different stations. It is a debatable issue when the first human voice was heard over the radio. But there are several ideas for when it was. By this time, people were experimenting with different ideas on radio waves.
The Radio Evolves In 1954, a small Japanese company called Sony introduced the first transistor radio. FM radio was developed to decrease static. All of these things lead up to the radio we know today.
The Beginning of the Radio In the 1860's a Scottish physicist, James Clerk Maxwell discovered the existence of radio waves. In the year of 1866, an American Dentist, Mahlon Loomis successfully demonstrated the use of wireless telegraphy. Many people experimented with the use of radio waves. In 1895 an Italian inventor, Guglielmo Marconi sent and received his first radio signal. In 1905, he developed the first radiotelegraph messaging.

When people started to broadcast on the radio, people were thrilled. Everyone wanted to hear the broadcasting, and radios were not just for boats anymore.
The first real radio broadcast was in 1915, when speech was transmitted from New York to San Francisco. On November 2, 1920, Westinghouse's KDKA started a daily broadcasting schedule.

Worldwide there are more than 2 billion radio sets in use, or about 1 radio for every 3 people.
