Bombo Radyo Philippines

Its flagship station, Bombo Radyo Iloilo, based in Iloilo City, was founded on July 6, 1966. Since the beginning of operations, the station's studios were located inside the Florete Building on Mapa Street in Iloilo City Proper, until they were relocated to the Bombo Radyo Broadcast Center alongside Luna Street in La Paz District. The station has been the top radio station since its inception during the 1970s.

DYFM was then part of the Northern Broadcasting Corporation. Don Marcelino, the grand old man of Bombo Radyo, accepted a joint venture agreement with former Ilocos Sur Governor, Antonio D. Villanueva, enabling the station to begin its broadcasts.

From humble beginnings and starting with a small number of employees, the Florete Group then acquired the operations of NBC with ten stations and two affiliates in the whole archipelago. It also entered a management alliance together with Consolidated Broadcasting Systems, Newsounds Broadcasting Network and People's Broadcasting Service. From 1967 to 1975, Bombo Radyo Philippines established every station in Laoag, Vigan, Cauayan, Bacolod, General Santos, Palawan, Baguio, Daet and Davao.

In 1976, Dr. Rogelio Florete, through the advice of his mother Doña Salome Florete, had started to helm the day-to-day operations of Bombo Radyo. In the same year, the network launched its first FM station DYRF. From then on, the network continued to expand to several markets, including the acquisition of DWXB from Universal Broadcasting Network in 1987, which would later on carry the call letters DWSM.
