February 13 is World Radio Day, which celebrates the radio as a way of educating people, providing information, and promoting freedom of expression across cultures. World Radio Day is an annual United Nations (UN) event that promotes the importance of the radio in communicating information worldwide.

Each year the United Nations Educational, Scientific, and Cultural Organization (UNESCO) celebrates World Radio Day by planning activities with broadcasters, organizations and communities around the world.

Despite being over 100 years old, the radio is one of the most popular ways to exchange information, provide social interchange, and educate people all over the world. The first World Radio Day was officially celebrated in 2012.
