What is a radio?


What does “radio” mean?

The word “radio” is derived from the Latin word “radius” and it means “beam of light” which is a little bit weird because there is no beam of light when you use the radio. It was first applied for communications in 1881.


Who invented the radio?

The question of who invented the radio comes with a large portion of controversy. In 1893 the Russian inventor Nikolai Tesla demonstrated a wireless radio in Missouri. However it’s often Guglielmo Marconi who is credited as the inventor of the radio. The reason behind this is that he was the first one ever to be given a patent for the wireless telegraphy technology in England in the year 1896. A year later Tesla filed his patents for his radio in the United States of America and they were granted in the late 1900. The final win for Marconi in this battle was when he was the first person ever to transmit signals across the Atlantic Ocean on December 12, 1901.


During World War 1

Before the 1920s the radio was only used for ships to communicate when they were out at sea. Radio communications was sent with Morse code messages, which were sometimes hard to interpret from long distances. During emergency situations – good communication was a great benefit to the vessels in the water and could change the outcome of battles. During the war the radio was one of the most important inventions for the army and thereby the countries invested a lot of money in the production and development of radios.


Radio today

Today the radio is one of the world’s most important inventions – far greater then Tesla or Marconi ever could have imagined. Today radios are found in homes, cars, computers and phones. There are approximately over 10 000 000 000 radios in the world.
