World Radio Day is a global initiative to celebrate radio as a medium, to improve international cooperation between broadcasters and to encourage major networks and community radio alike to promote access to information, freedom of expression and gender equality over the airwaves.

Radio is the mass media reaching the widest audience in the world. It is also recognised as a powerful communication tool and a low cost medium.

This year, UNESCO focuses on encouraging radio stations around the world, whether a community, private, or public radio station, to have the tools to be the best radio stations they can be. And that means ensuring they are having continued dialogue with the industry, its audience and the public in general.
