In 2011, UNESCO Member States proclaimed  February 13 as World Radio Day. A year later, in 2012, the United Nations General Assembly officially recognized the date within the United Nations system, in acknowledgement of the unique value of radio as a means of communication.

The International Association of Broadcasting (IAB) was one of the pioneering organisations in actively promoting and supporting this process, contributing to the establishment of a day dedicated to celebrating one of the most influential and accessible media.

Radio plays a fundamental role globally and, to this day, remains the most widely used medium of communication in the world. Through radio, we learn about what is happening in every corner of the planet and share stories, information and culture. It has accompanied different generations and, far from losing its relevance, continues to adapt and strengthen its presence in everyday life.

Throughout history, radio has been the voice of those who had no voice, a space for resistance against authoritarianism and a key tool for the defence of democracy. Its diversity of content, perspectives and formats promotes public debate, pluralism of ideas and the full exercise of freedom of expression.

Radio has also made it possible to connect small, remote communities that often have no access to other means of communication. In these contexts, radio plays an essential role by informing people, broadcasting alerts and emergency announcements, and ensuring that nobody is excluded from access to information.

For all these reasons, and many more, celebrating World Radio Day reaffirms the importance of radio as a medium. It is also an opportunity to promote international cooperation between broadcasters, encouraging both large networks and local radio stations to continue strengthening press freedom and freedom of expression.

The celebration in 2026 will be held under the slogan 'AI is a tool, not a voice'.

Artificial intelligence now occupies an increasingly important place in our society. It facilitates access to information, helps us to understand complex issues and optimises many daily tasks. However, AI is not a voice; it is a tool.

When used responsibly, AI can enhance the quality of radio content, boost accessibility, and streamline production processes. However, it cannot replace the human values, sensitivity, professional judgement and credibility that radio professionals develop day after day.

When used ethically and in the public interest, to support creativity, editorial judgement and the values of radio professionals, AI can strengthen audience trust.
