Radio is one of the most amazing and effective inventions of the last century. Radio Pakistan came into being with the independence of Pakistan in 1947. From the very beginning, Radio Pakistan made many efforts for the promotion and development of Urdu language, consciously and unconsciously. Urdu programs were started from Radio Pakistan to acquaint people with Urdu language. Later, Urdu experts were hired to correct the accent and pronunciation of Urdu language. The services of Radio Pakistan are very important in popularizing Urdu poetry through music. Drama is an important genre of literature and radio played an important role in bringing and popularizing Urdu drama to the masses. Many radio dramas of Radio Pakistan were later published in book form and proved to be an important addition to Urdu literature. Another important service of Radio Pakistan in relation to the promotion of Urdu language and literature is the publication of the Urdu radio magazine "Ahang". "Ahang" is the only Urdu magazine of Pakistan which has been continuously published since 1948. In short, services of Radio Pakistan for the promotion of Urdu language and literature have been assessed thoroughly.
