Radio was invented by Marconi in 1904.  Since 1924 the radio has been serving the people in every part of the world.
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.
James Clark Maxwell and Michael Faraday arrived at the theoretical conclusion that electromagnetic waves existed and Heinrich Hertz, another scientist, confirmed and proved that electromagnetic waves can be transmitted. Guglielmo Marconi, an Italian inventor fascinated by Hertz’s study on electromagnetic waves, further experimented by sending radio transmissions, which led to the development of wireless telegraphy.
Early theoretical and experimental innovations by scientists such as David Hughes, Nikola Tesla, Jagdish Chandra Bose and others have also contributed to the development of radio communication systems as they exist today. The sound you hear on your radio sets are signals transmitted through electromagnetic waves in a radio frequency range.

Fun facts
·       Did you know that the radio is ranked number two in the list of ‘101 Gadgets that Changed the World’ according to History Channel? It is second only to smart phones.
·       One incident that truly demonstrated the power of the radio way back in the 1930s is the dramatization of H.G. Wells’ “The War of the Worlds”. On October 30, 1938, a regular programme was interrupted by a news bulletin announcing the invasion of earth by Martians, and what followed was utter panic and chaos. It was later found that the radio adaptation of the science fiction was altered to present it in a more realistic way.
·       This is not so much a fun fact, but a fact nevertheless that mentions radio. In 1979, the British musical duo, “The Buggles” released the hit song “Video Killed the Radio Star”, the lyrics of which implied that by combining audio and visual effects, television had made the radio — a thing of the past or obsolete.
·       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.



A 2009 study by The Council for Research Excellence (a consortium of researchers representing advertisers, agencies, networks and cable companies), called "How U.S. Adults Use Radio and Other Forms of Audio," found that broadcast radio remains the dominant form of audio consumed at home, work and in the car. "Broadcast radio reaches those aged 18-34 at rates equivalent to the general adult population, with 79.2% of younger adults listening to broadcast radio for an average of 104 minutes a day among listeners," reported the study. Thus, while radio faces distinct challenges, it remains a medium of vast importance to the public.
If properly managed, radio programs may work wonders in the socio-cultural life of a country. From our radio sets we listen news, music features, speeches, dialogues, discussion on the social problems guidelines in the matter of education, and talk on various matter on daily life. The speared of knowledge has become quicker and easier with the help of radio while sitting in our comfortable drawing rooms, we may listen to a great leader or speaker on the air.
