The thirteenth of February was World Radio Day, a date set by UNESCO to celebrate and recognize radio for all that it is. According to UNESCO, despite the growing influence of the Internet and social networks, radio continues to be a prime source of information and entertainment. So, this World Radio Day we talk to UNESCO Communications Chief Mirta Lourenço about the importance of radio and its tenacity. After that, we learn about Cádiz's Carnaval chirigotas, and hear a sweet Valentine's tune.
