World Radio Day is observed on 13 February each year to mark the anniversary of the first-ever broadcast made by Reginald Fessenden on a regular commercial basis, using a 100-watt transmitter powered by a water-cooled power generator at Brant Rock, Massachusetts, in 1906. World Radio Day was announced on December 14, 2015. On this day, the International Telecommunication Union (ITU) and UNESCO marked the date to celebrate the role of radio in uniting people across borders. Also, it is a reminder that access to information can help societies flourish. As we look back at World Radio Day 2016, it's a good time to take stock of how far we have come and where we are going as we continue our journey toward digital broadcasting. History of the World Radio Day World Radio Day is an international holiday that celebrates the art of radio and the important role it plays in our lives. It began on 13 February 2001, when UNESCO first suggested that every year should be celebrated as World Radio Day. The date was chosen because it coincides with the birthday of Guglielmo Marconi, who is regarded as the inventor of radio communications. The idea for World Radio Day came about after Marconi's death when the United Nations Educational, Scientific, and Cultural Organization (UNESCO) decided to commemorate his work by declaring a special day. The day is celebrated by thousands of radio stations and millions of listeners around the world. In 2002, the United Nations General Assembly proclaimed 21 November as World Radio Day. The date was chosen because it is the anniversary of the birth of Marconi in 1874. How to Celebrate World Radio Day The day is celebrated by radio stations around the world. Many stations broadcast special programs, and some even offer prizes to listeners who can guess the number of radio sets in their area. The celebration of World Radio Day is also an opportunity for broadcasters to raise awareness of the importance of radio in their communities. In some countries, special broadcasts are transmitted on shortwave frequencies to other countries. These transmissions are usually intended for audiences who do not have access to local radio stations. For example, in2017, the BBC World Service transmitted a special program to its audiences in Sierra Leone. The program was intended to raise awareness of the importance of media freedom and free speech in that country. Other organizations, such as UNESCO, also use World RadioDay to highlight the importance of radio in their work. The UN General Assembly has designated February 13 as World Radio Day since 2011.
