World Radio Day is celebrated on February 13 every year to acknowledge and celebrate the significance of radio in shaping society and culture globally. It is a day to recognize the importance of radio in promoting information, education, and entertainment across diverse communities. PM greets everyone on the occasion of World Radio Day.

When Radio was Broadcast in India?

February 13 is observed as World Radio Day. Member countries observe February 13 as World Radio Day in honor of theUnited Nations‘ launch of radio broadcasting on February 13, 1946. Radio was first broadcast in India in 1923. The theme for World Radio Day 2025 is ”Radio and Climate Change.This day assists radio stations in their journalistic coverage of this critical problem.

This Day was proclaimed in 2011 bythe Member States ofUNESCOand adopted by the United Nations General Assembly in 2012 as an International Day, and February 13 became World Radio Day (WRD). Radio is a powerful medium for celebrating humanity in all its diversity and constitutes a platform for democratic discourse.

In the mid-1890s, building on techniques physicists were using to study electromagnetic waves,Guglielmo Marconideveloped the first apparatus for long-distance radio communication.

The invention of radio communication was preceded by many decades of establishing theoretical underpinnings, discovery and experimental investigation of radio waves, and engineering and technical developments related to their transmission and detection. These developments allowed Marconi to turn radio waves into a wireless communication system.

The idea that the wires needed for electrical telegraph could be eliminated, creating a wireless telegraph, had been around for a while before the establishment of radio-based communication. Inventors attempted to build systems based on electric conduction, electromagnetic induction, or on other theoretical ideas. Several inventors/experimenters came across the phenomenon of radio waves before its existence was proven; it was written off as electromagnetic induction at the time.

The discovery of electromagnetic waves, including radio waves, by Heinrich Rudolf Hertz in the 1880s came after theoretical development on the connection between electricity and magnetism that started in the early 1800s. A gadget World Radio is a Modern battery-operated portable shortwave radio receivers often called world radio or world band receivers are marketed primarily to those wishing to receive international broadcasts and are offered in a range of compact “travel size” to smaller “pocket size” units.

Indias Prime Minister Narendra Modi greeted everyone on the occasion of World Radio Day. He also invited everyone to share their ideas and inputs for this months Mann Ki Baat, scheduled on the 23rd.

In a post on X, Shri Modi wrote:

Happy World Radio Day!

Radio has been a timeless lifeline for several peopleinforming, inspiring and connecting people. From news and culture to music and storytelling, it is a powerful medium that celebrates creativity.

I compliment all those associated with the world of radio. I also invite you all to share your ideas and inputs for this months #MannKiBaat, which will take place on the 23rd-(23rd February 2025).

During some other experimenters, Oliver Lodge and Jagadish Chandra Bose, explored the physical properties of electromagnetic waves, and they developed electric devices and methods to improve the transmission and detection of electromagnetic waves.

In the mid-1890s, building on techniques physicists were using to study electromagnetic waves, Marconi developed the first apparatus for long-distance radio communication. On 23 December 1900, the Canadian-born American inventor Reginald.

By 1910, these various wireless systems had come to be called “radio”.

From a long view of the history of the worldseen from, say, ten thousand years from nowthere can be little doubt that the most significant event of the 19th century will be judged as Maxwell’s discovery of the laws of electromagnetism.”
