Long before televisions flickered in living rooms and smartphones lit up in pockets, a single voice travelling through the air kept entire villages informed. Radio broadcasting was, for decades, the most powerful tool of mass communication in the country, and despite the rise of newer technologies, it has refused to fade away. Its strength lies in something deceptively simple: sound. A spoken word can reach a farmer in a remote field, a fisherman at sea, and a student in a crowded city all at once. This post explores how radio became such a dominant medium, why it continues to matter, and where it is headed in an increasingly digital world.

The reach and characteristics of radio broadcasting
Radio is a one-to-many medium that transmits sound through electromagnetic waves to receivers spread across vast distances. What sets it apart from print and television is its low cost, portability, and ability to function without electricity-dependent infrastructure or literacy. A battery-powered transistor set in a tea shop can serve dozens of listeners at once, which is why radio took root so deeply in a country with diverse geography and uneven access to modern amenities.
The story of organised broadcasting here began in the 1920s with amateur radio clubs in Bombay, Calcutta, and Madras experimenting with wireless transmissions. The Radio Club of Bombay aired programmes in June 1923, followed soon after by Calcutta and Madras. These early efforts evolved into the Indian State Broadcasting Service, which was renamed All India Radio and aired its first broadcast on 19 January 1936. In 1956 it formally adopted the name Akashvani, a Sanskrit term meaning “voice from the sky.”
Why radio remains strong in remote areas
The most striking characteristic of radio is its ability to penetrate places where other media struggle. All India Radio’s terrestrial signal reaches 99.20% of the population across 92% of the country, making it the primary source of news and information in many rural regions. This kind of coverage is difficult and expensive to match through newspapers, which depend on distribution networks, or through the internet, which depends on connectivity and devices.
Radio is also resilient during emergencies. When cyclones, floods, or other disasters knock out power lines and disrupt mobile networks, battery-operated radio sets keep working. Community stations have repeatedly proven this value. When cyclone Fani struck Odisha in 2019, Radio Surabhi issued warnings and guided people in danger zones toward shelters. This reliability under pressure is one reason governments and disaster-management agencies continue to treat radio as essential infrastructure rather than an outdated tool.
Scope and accessibility across diverse audiences
One of radio’s greatest social contributions is its accessibility to people regardless of their reading ability. In a nation where literacy is still uneven, the spoken word removes a major barrier. Information that would be locked away in a printed pamphlet becomes available to anyone who can hear. This is precisely why audio-based communication has been called the most effective channel in many areas. As one community radio jockey in Haryana’s Nuh district explained, high illiteracy in the area means only audio can ensure effective communication.
The medium also embraces linguistic diversity in a way few others can. All India Radio broadcasts in around 23 languages and 179 dialects, covering communities whose languages may not even have a widely used written form. This multilingual reach allows a single broadcasting network to speak directly to hundreds of distinct cultural groups, preserving local identity while connecting them to the national mainstream.
The rise of community radio
Beyond the national network, community radio has emerged as a grassroots layer of broadcasting that serves small populations with hyper-local content. A landmark 1995 Supreme Court judgment declared airwaves to be public property meant to advance public good, which laid the legal foundation for community broadcasting. These stations are often run out of small rooms with minimal staff, yet they air content in local dialects produced by local people.
Their impact during crises has been remarkable. During the Covid-19 lockdown in 2020, a community radio station in Maharashtra’s drought-hit Satara district broadcast school lessons by local teachers so children without internet access could keep learning. The Confederation of Indian Industry has noted that community radio has become a trustworthy alternative to mainstream media in rural areas, keeping ethnic languages and cultures alive in far-flung villages while covering more than just local news. To strengthen this further, the Ministry of Information and Broadcasting introduced revised policy guidelines on World Radio Day in February 2024 to expand the effectiveness of community radio stations.
Balancing entertainment and education
Radio’s enduring popularity rests on its ability to entertain and inform in the same breath. The medium has always woven music, news, and conversation into a continuous stream that holds attention without demanding undivided focus. Listeners can cook, farm, drive, or work while the radio plays in the background, a flexibility that visual media cannot offer.
Music, news, and talk shows
Entertainment has been central to radio from the start. The Vividh Bharati Service, launched in 1957, focused on popular film music and remains beloved across generations. All India Radio also played a major role in preserving classical traditions, founding the Akashvani Sangeet Sammelan in 1954 as an annual showcase of Indian classical music. Legendary artists such as M.S. Subbulakshmi and Lata Mangeshkar were closely associated with its broadcasts.
At the same time, radio served serious public purposes. According to the Ministry of Information and Broadcasting, AIR was instrumental in spreading messages about literacy, health awareness, and agricultural knowledge after independence. Weather updates, family planning campaigns, and government welfare announcements all travelled through the airwaves to citizens who could not access other media. Farm broadcasting deserves special mention here, as dedicated Farm and Home units helped make radio a genuine agent of social change in rural and farm communities.
The talk-show format adds yet another dimension. Live phone-in programmes connect listeners directly with experts, doctors, and officials. The Prime Minister’s monthly programme Mann Ki Baat demonstrates how a talk format can engage diverse audiences across the country, with community stations permitted to rebroadcast it for their listeners. This blend of music for relaxation, news for awareness, and talk for participation is what keeps radio woven into daily routines.
The future of radio in a digital world
Far from being replaced by digital technology, radio is absorbing it. The transition from analog to digital transmission is already underway through Digital Radio Mondiale, or DRM, which improves sound quality and extends reach into remote and border areas. Pure DRM transmissions have been introduced in Mumbai, Kolkata, Delhi, and Chennai, with dedicated channels such as AIR News 24×7 and AIR Raagam 24×7, and car manufacturers like Hyundai and Maruti Suzuki have begun fitting new models with DRM receivers.
The internet has expanded radio’s footprint rather than shrinking it. All India Radio’s content now travels worldwide through the NewsOnAir app, podcasts, and official websites, integrating traditional broadcasting with modern digital media. The app offers over 200 live streams accessed by listeners in many countries, giving the network a genuinely global audience.
The podcasting wave
The clearest sign of radio’s evolution is the explosive growth of podcasting, which is essentially on-demand audio for the smartphone era. The country has already become the third-largest podcast market in the world, behind China and the United States, with listenership crossing 105 million in 2024 and projections pointing toward 200 million. This boom is driven by cheap data, rising smartphone ownership, and demand for localised content.
Crucially, podcasting is following the same path that made radio successful: regional language content. Platforms now offer podcasts in Hindi, Tamil, Telugu, Marathi, and other languages, bringing audio content to millions who live outside metro areas and do not speak English. Genres have widened well beyond news and education into comedy, culture, and true crime, signalling a maturing audio ecosystem.
It would be a mistake to read this digital shift as the death of traditional radio. Global data shows that AM/FM radio audiences among adults aged 25 to 54 grew by 6% year-over-year, and broadcast radio is projected to surpass linear television in ratings among that age group. The lesson is that audio as a medium is thriving in all its forms. Broadcast radio holds its ground through reliability and free access, while podcasting captures the convenience of personalised, on-demand listening. Together they confirm that the human appetite for the spoken word is stronger than ever.
What do you think? Will broadcast radio and on-demand podcasting continue to grow side by side, or will one eventually overshadow the other? And in an age of endless visual content, what is it about a human voice travelling through the air that keeps drawing listeners back?
