Tuesday is "World Radio Day".
It's a day promoted by the United Nations Educational, Scientific and Cultural Organization.
Chief of Media Development Mirta Lourenco says the initiative shows the importance of local radio.
This year's theme is celebrating radio's impact on sport at a grassroots level.
The message is that radio should show diversity in sports coverage, especially among women.
Lourenco stresses remote and rural areas rely on radio as their information provider.
