The French military opened the first radio broadcasting station in Dakar in 1932. It began broadcasting civilian programming in 1939. The origins of RTS are in Radio-Dakar, created in 1950, that broadcast eight hours per day. In 1951 two channels appear: Dakar Inter and Dakar Afrique, broadcast to listeners across western Africa. In 1959, the fusion of Mali and Senegal into the Mali Federation causes the creation of Radio Mali, its bases being in Radio Inter. On August 20, 1960, when Senegal separated from the Mali Federation, Radio Mali became Radio Senegal with two channels: one national and the other international. -sponsored functional literacy class for co-operative farmers in the city of Khenene in 1971 In 1962, Radio Senegal became the flagship member of the Union of African National Television and Radio Organizations and its successor, the African Union of Broadcasting. In 1965, the Senegalese government began its first television broadcasts, which come to an end in 1972. However, the Munich Olympics created a demand that incited the Senegalese government to create an institution producing both television and radio broadcasts. The Office de Radiodiffusion Télévision du Sénégal was created in 1973, operating two radio channels and a national television channel. On 4 October 1973, ORTS which had been in talks with Radio Gambia about producing a joint radio programme based on Senegambian history and broadcast in the local languages came to an agreement, and the first ever recording of the programme Chossani Senegambia was made. The Gambian team consisted of veteran broadcasters like Alhaji Alieu Ebrima Cham Joof, Alhaji Assan Njie, Alhaji Mansour Njie and Alhaji Ousman Secka. Alhaji Alieu Ebrima Cham Joof travelled to various parts of Senegal and the Gambia accompanied by his team of journalists including Cheickh Jallow, to interview the elders knowledgeable in Senegambian history. The Senegalese team also went to the Gambia to gather materials. Their team included: Ebrima Mbenga, Dodou Diego Diop and Alioune Cissé. The programme was pre-recorded and it was scheduled by both Radio Stations to go live at the same time and date, so that both Gambian and Senegalese listeners can listen to it at the same time. On many occasions, prominent Senegalese historians made live appearances at Radio Gambia studios and vice versa. The programme was generally accompanied by live music from prominent griots like Jali Nyama Suso, Alhaji Bai Konte, Alhaji Abdoulaye Samba and backing singers. Some of the prominent historians from Senegal that appeared on the programme included: El Hadji Demba Lamin Diouf, Modou Diouf, El Hadji Mansour Gueye and Gorgi Makura Mboob. From the Gambia they included: Dodou Nying Koliyandeh, Jabell Samba, Alhaji Babou Samba, Alhaji Bamba Suso, Doctor Lamin Mbaye, Alhaji Momodou Lamin Bah and Alhaji Sait Camara. The programme was a success in both Senegal and the Gambia, because no programme like that existed before in neither country. In 1992, the ORTS changed its name to the Société Nationale de Radiodiffusion Télévision Sénégalaise also changing its structure from government direction to a publicly funded, independently managed corporation.
