A celebration today of radio.
This year World Radio Day, an effort by United Nations Educational, Scientific and Cultural Organization, or UNESCO, to promote the importance of radio.
Chief of Media Development Mirta Lourenco says this year's theme focuses attention on radio and sports.
"The message is that radio should show diversity in sports coverage. Which would include gender diversity, that is more coverage of women's sports...women in sports."
Lourenco also encourages radio stations to cover more grassroots sports.
