During colonial rule, the erstwhile Travancore State set up the first Radio Station. The Princely State of Travancore has granted sanction for the establishment of a Broadcasting Station at Thiruvananthapuram, on 30th September 1937. His Highness the Maharaja Travancore showed great interest in broadcasting and formed a committee of the top officials to evaluate the possibility of installing a Transmitter at the capital Thiruvananthapuram. His Highness Sri Chithira Thirunal Balarama Varma inaugurated the Travancore State Broadcasting Station on 12th March 1943. The 5 KW Medium Wave Transmitter was installed at Kulathur and the Studio was located at old MLA Quarters. At that time two hours broadcasting on Friday evenings were aired by the station. Later it increased to Four day broadcast per week. After Independence when the Princely State of Travancore has joined in Indian Union, the Travancore Broadcasting Station also merged with All India Radio Network from 1st April 1950.
