World Radio Day

The best way to relax is to turn on some music, and if you want to stay informed about what’s happening in the world, it’s worth listening to the latest news. For both, radio is the perfect companion. Not everyone knows there’s a holiday dedicated to it—World Radio Day, traditionally observed on February 13.

History

Historians believe that the discovery of radio waves belongs to scientist Heinrich Hertz, whose name is still familiar worldwide. He made them audible with a special device called a transmitter, to which antennas were connected. Experiments lasted for several years, but the word “radio” was only first used at the end of the 19th century. French physicist Édouard Branly, credited with inventing the radio semiconductor, was among those who helped shape its development.

Radio quickly captured public interest and gained popularity across the globe. It wasn’t just a source for important information; it also brought music, stories, and live broadcasts into people’s homes. The impact of radio was so significant that it led to calls for a dedicated holiday. In 2011, UNESCO declared World Radio Day as an international observance.

Interesting Facts

• Some of history’s most important announcements were first broadcast on the radio. For example, the people of Japan heard the voice of their emperor for the very first time when he announced the country’s surrender during World War II.
• In 1938, a radio play based on “The War of the Worlds” convinced some listeners that the country was truly under attack by aliens. Many panicked, believing the White House had been burned down and invaders were about to seize power.
• Radio remains relevant today, even as most people now use the Internet for news and entertainment.

How to Take Part

Take your old radio out of the closet and set aside all other sources of news and music for the day. Try spending the whole day tuned in to radio broadcasts. You could even host a radio-themed party and invite your friends. The only rule: no Internet! Imagine a world before the web was invented. Time will fly, and everyone will experience something new.
