February 13 is World Radio Day.


Who Invented Radio?
The word radio is derived from the Latin word radius which means ‘ray’. The term was adopted in the early 20 century to distinguish the radio from other wireless communication technology.
Two scientists, James Clark Maxwell and Michael Faraday arrived at the theoretical conclusion that electromagnetic waves existed. Heinrich Hertz, another scientist, later on, experimented and confirmed the findings of Maxwell and Faraday and proved that electromagnetic waves can be transmitted.
Guglielmo Marconi, was an Italian inventor, who is known as the father of long distance radio transmission. Fascinated by Hertz’s study on electromagnetic waves, Marconi further experimented by sending radio transmissions, which led to the development of wireless telegraphy.

Why Celebrate World Radio day?



World Radio Day seeks to raise awareness about the importance of radio, facilitate access to information through the radio and enhance networking among broadcasters. It was proclaimed on November 3, 2011 by UNESCO, and was originally proposed by Spain. According to the UNESCO’s website, World Radio Day is “a day to celebrate radio as a medium; to improve international cooperation between broadcasters; and to encourage major networks and community radio alike to promote access to information and freedom of expression over the airwaves.”
Any radio organization will be able to freely download content available to celebrate World Radio Day by broadcasting all day, on February 13, 2013, audio messages on the importance of radio from all over the world.
Radio is still used by many Millions around the world
Did you know that the radio is ranked number two in the list of ‘101 Gadgets that Changed the World’ according to History Channel?

Despite highs and lows, the radio is still a low cost medium and a source of information and entertainment that reaches out to a large number of people around the world.
Radio is a medium of communication that allows people to listen to news, music and other forms of entertainment. The sound you hear on your radio sets are signals transmitted through electromagnetic waves in a radio frequency range.

Today, there are over 1, 00,000 radio stations around the world. Worldwide, there are more than two billion radio sets in use — a proof that video never killed the radio star.
