MUMBAI: When the internet drops, when mobile networks fail, when power cuts darken screens, one medium still finds a way to speak. Radio. No passwords, no data plans, no scrolling, just a human voice and a willing ear.

That enduring power is why 13 February is observed globally as World Radio Day. First proclaimed by UNESCO in 2011 and later adopted by the United Nations General Assembly in 2012, this day recognises radio’s invaluable contributions to information, community cohesion and freedom of expression. Radio reaches both megacities and the most remote hamlets, carrying local voices into global conversations across India and beyond.

Why 13 February matters
The date marks the 1946 launch of United Nations Radio, created to share news about world affairs and promote dialogue after the devastation of World War II. In a world rebuilding fractured societies, radio’s ability to traverse borders and connect communities was and remains unparalleled.

Radio’s renewed relevance in crisis and community

1. A lifeline when everything else fails
   Across disasters, conflicts and shocks to infrastructure, radio often remains the most reliable channel for real-time information.

In India during the initial COVID-19 lockdown, radio listenership grew by about 23 per cent, and 82 per cent of the population tuned in for news and updates on the pandemic. This surge underlined radio’s role as a trusted source of verified information when people were confined to their homes with limited access to other media.

Emergency broadcasts guided communities on containment measures, shared helpline numbers and countered misinformation, often in local dialects that other media overlook.

2. Education without walls
   Radio has long supported learning outside classrooms. During pandemic restrictions, when schools were closed, several radio stations across India aired educational programmes for children who lacked internet or devices. The medium’s simplicity, a basic receiver, meant listening was possible even in low-connectivity regions.

This inclusive reach helps adult farmers learn new techniques, women access health advice, and students continue learning even when textbooks are unavailable.

3. Bringing voices into the mainstream
   Often, radio serves as the voice of the marginalised. Community radio stations broadcast in local dialects, discuss grassroots issues and elevate stories that national media rarely capture.

According to research on community radio stations in India, around 63 per cent of interviewed listeners reported tuning in daily, attracted by locally relevant content tailored to their communities’ needs.

Human stories behind the statistics

1. Sangham Radio: women’s voices on the airwaves
   In rural districts of Telangana, Sangham Radio, India’s first all-female community radio station, broadcasts programmes developed and presented entirely by Dalit women. It serves about 40 villages and covers topics ranging from farming and health to women’s rights and local culture.

Listeners have credited the station with empowering women, fostering legal awareness and even helping find lost livestock. It stands as a clear testament to how radio can serve as both an information source and a social change agent.

2. Radio Mattoli: voter awareness in remote tribal hamlets
   In the forests of Wayanad, Kerala, community station Radio Mattoli has been instrumental in promoting civic participation. Ahead of elections, its broadcasts in several tribal dialects encouraged residents in isolated hamlets to vote, helping reach turnout numbers that rival those in urban centres. Radio’s ability to speak directly in people’s own languages proved essential in reaching audiences beyond conventional campaign channels.
3. Radio Mewat and health awareness
   In Nuh, Haryana, community radio played a critical role in healthcare communication by organising awareness camps and broadcasting information on government health schemes such as Ayushman Bharat. These efforts significantly boosted local uptake of healthcare services, illustrating radio’s ability to catalyse real behaviour changes in rural populations.
4. Agricultural advice changing lives
   Government studies show that farmers who listened to agricultural programmes on community radio adopted improved techniques, from organic manure application to pest management, which boosted crop yields and increased incomes. In one community, pulses yields increased significantly after farmers shifted practices based on advice heard on radio.

Radio’s emotional resonance in everyday life
In India’s villages, radio remains more than a medium. It is part of the daily rhythm. Before dawn, a transistor might play devotional songs. By sunrise, it delivers news and weather. During long days in the fields, radio accompanies farmers. In evening gatherings, it becomes a shared experience.

Elderly listeners often describe radio presenters as familiar voices, friends in isolation. For many migrants living away from home, radio broadcasts in their native languages offer comfort and continuity. In households where literacy is not universal, radio’s spoken word bypasses barriers and creates inclusion.

Global relevance beyond India
Radio’s reach is not only local. It is global. UNESCO surveys estimate that radio continues to be among the most accessible mediums in developing countries, with penetration rates often exceeding 75 per cent. This broad reach makes radio indispensable in regions where internet access remains limited.

World Radio Day celebrations increasingly spotlight radio’s role in tackling contemporary challenges such as climate change communication, where community radio helps communities prepare for and respond to extreme weather events. Experts stress the importance of local language programming and inclusive participation in climate discourse.

Beyond nostalgia: Radio’s evolving future
Despite predictions that digital media would eclipse it, radio has adapted. Traditional FM and AM broadcasts now coexist with digital audio streaming, podcasts and hybrid apps. Major broadcasters such as BBC and All India Radio integrate online streams with terrestrial stations, expanding reach while retaining local relevance.

But radio’s essence remains the same. A human voice connecting with millions regardless of geography or economic status. It does not require literacy or costly technology. It only needs openness to listen.

A medium that still matters
World Radio Day celebrates not just radio’s storied past, but its living impact in today’s world. In emergencies, it informs. In villages, it accompanies daily life. In communities, it empowers. Radio has outlasted many media trends because it speaks to the fundamental human need for connection and reliable information.
