Sulena Majumdar Arora Radio is a device where news, music and other events from around the world are broadcast. The history of radio is very interesting because its service has been present in the world for more than a hundred years and many technological changes are taking place continuously in it. The first successful radio transmission occurred in 1901 when Guglielmo Marconi sent a message across the Atlantic Ocean. By the 1920s, radio broadcasting had become a popular source of entertainment and information, with radio stations spreading throughout the world. During World War II, radio played an important role in disseminating news and propaganda, and the development of portable radios enabled soldiers to stay connected to the outside world. In the modern era, television threatened radio’s popularity, but radio eventually managed to survive by emphasizing music, talk shows, and news programs. The advent of digital technology in the 21st century significantly changed the way radio is broadcast, with many people now listening to radio via the Internet and mobile devices. Despite these changes, radio remains an important medium of communication and entertainment, connecting people around the world. World Radio Day on 13 February, designated by the United Nations Educational, Scientific and Cultural Organization (UNESCO), provides an opportunity to recognize the invaluable work of radio in our lives. Radio has been a main source of communication and entertainment for over a hundred years, serving as a platform for sharing news, music and ideas around the world. Radio is an easy and inexpensive medium to stay connected with news and entertainment from around the world that reaches people in all corners of the globe, from urban to rural areas. This year’s theme, “New World, New Radio,” defines radio’s flexibility and innovation with changing times. In the midst of the COVID-19 pandemic, radio played a vital role in spreading credible health messages to the public. Especially for those people who did not have access to internet or media. In addition to its role in informing and educating the nation and the world, radio has the unique ability to engage people through entertainment. From music to talk shows and sports broadcasts to various programs, radio provides all services to the general public free of charge. The celebration of World Radio Day is an occasion to recognize the important role of radio in our lives and to honor the dedicated radio workers who work tirelessly to bring us news, music and entertainment every day. World Radio Day provides an opportunity to celebrate the impact of radio on our world and to acknowledge its important role in our lives.
