It was in the 1920's that radio broadcasting started in India. It was begun by some Clubs in Calcutta and Chennai. These clubs were interested in arts and they started radio broadcasting, not with any financial motive. In the 1940's, radio broadcasting became a government air. In the Second World War, the Indian Radio became a means of propaganda for the Allied Powers (Britain, France, and America).
When India got freedom there were only 6 radio stations in India. They were broadcasting only for the people of cities. The 1950's, with the coming of transistors, radio became more popular. In those days a license was needed to keep a radio. By 1950, some 546,200 licenses were issued. Famous women like Amita Roy were working in the All India Radio.
