When was the radio made?
Guglielmo Marconi (the inventor) successfully sent the first radio message across the Atlantic Ocean in December 1901 from England to Newfoundland, Marconi's radio did not receive voice or music. Rather, it received buzzing sounds created by a spark gap sending a signal using Morse code (Morse code is a series of clicking noises that are able to be translated into words if you know it). It was first made in 1898
How does the radio work?
The radio receives electromagnetic waves from the air that are sent by a radio transmitter. Electromagnetic waves are a combination of electrical and magnetic fields that overlap. The radio converts these electromagnetic waves, called a signal, into sounds that humans can hear.
When and what was the first broadcast on the radio?
Reginald Fessenden transmitted the first radio broadcast in history from Brant Rock Station, Massachusetts. Ships at sea heard a broadcast that included Fessenden playing the song O Holy Night on the violin and reading a passage from the Bible.
What was a big use for the radio?
The radio came of age during World War I. Military leaders recognized its value for communicating with the infantry and ships at sea. During the WWI, many advancements were made to the radio making it more powerful and compact.
There is no single process for manufacturing a radio. The manufacturing process depends upon the design and complexity of the radio. The simplest radio has a single circuit board housed in a plastic case. The most complex radio has many circuit boards or modules housed in aluminum case.
Its golden age
On November 2, 1920 the first commercial radio station went on the air in Pittsburgh, Pennsylvania. It was a huge success, and began the radio revolution called the "Golden Age of Radio." The Golden Age of Radio lasted from the early 1920's all the way to the the late 1940's when the television brought in a whole new era. During this Golden Age, the radio evolved from a simple device in a bulky box to a complex piece of equipment. People would gather around the radio and listen to the latest news and radio plays. The radio occupied a similar position as today's television set.
