All India Radio Lahore began in 1937 and was the making of a generation of Punjabi and Urdu performers: Mohammed Rafi, Surinder Kaur, Prakash Kaur, and the writers and producers around them.
In 1947 the station went to Pakistan. All India Radio built a new station at Jalandhar in 1948, largely staffed by people who had come across, and it became the voice of Indian Punjab.
For four decades AIR Jalandhar was where Punjabi folk music was recorded, where Punjabi drama was performed, and where farm broadcasts told people what to sow. Its farm programme and Punjabi University's extension work between them carried the Green Revolution into villages.
Radio Pakistan Lahore did the same on the other side, and listeners on each side of the border tuned to the other's station because the signal carried and the language was the same.
Both archives hold recordings of Punjabi music and drama from the 1940s onward that exist nowhere else, and neither has been fully digitised or opened.
All India Radio Jalandhar has broadcast in Punjabi since 1948 and its programmes made the careers of a generation of singers and writers.
Radio Pakistan Lahore did the same on the other side, and the two stations were audible across the border, which is how each side heard the other's music through the closed decades.
Private FM in Punjab is commercial and urban and does very little in Punjabi that is not film music. Community radio exists at a handful of universities and almost nowhere else.
