For 75 years, AIR has been distinctive part of the Indian way of life. From a small beginning, in the form of radio clubs in 1927. With one of the largest network of SW/MW/FM transmitters, AIR, reaches the remotest corners of the country to serve the people. People living in far flung areas with modest means can also have access to its programmes if a small transistor radio set run on dry batteries is available with them. AIR functions on a moto “Bahujana Hitaya Bahujan Sukhaya” i.e. promote the happiness and welfare of the masses through education, information and entertainment. To this end it has evolved a three-tier system of broadcasting viz. national, regional & local. AIR services are operated through Primary Channels, the National Channel, Commercial Broadcasting Services (Vividh Bharti), FM Channels & External Services.
Today AIR has a network of 213 broadcasting centers covering 90% of the area & almost reaching the entire population of one billion.
