February 13
World Radio Day is observed on 13 February, which marks the day when the United Nations Radio was launched in 1946. Since its establishment, UN Radio has used its multilingual programmes carried by media outlets around the globe to tell the story of the international community’s efforts to meet the challenges of building a better world. Amid the rise of new technologies, radio remains the most accessible platform, a powerful communication tool and a low cost medium. Raising awareness of its unique value is one of the goals of World Radio Day that also seeks to improve international cooperation among broadcasters and encourage decision makers to provide access to information through radio.
