In 2011, UNESCO’s Executive Board brought a recommendation to the General Conference, and this recommendation was to institute a holiday dedicated to observing the importance of radio. This request was based on a proposal by Academia Espanola de la Radio and was supported by major international broadcasters, broadcasting associations, and broadcasting unions.
The date of February 13th was chosen because that’s the day when United Nations Radio was created in 1946. This date was approved at the 36th session of the General Conference. On January 14th, 2013, UNESCO’s proclamation was formally endorsed during the United Nations General Assembly’s 67th session, and the resolution was subsequently adopted.
