Subic Broadcasting Corporation (SBC) was first founded in 1969 as a daily radio companion of the people of Olongapo in providing news and entertainment. When it was incorporated on July 29, 1969 it began broadcasting on the AM frequency 1557 kHz as DWGO "Radio on the Go". After being temporarily closed during martial law in 1972, it resumed operation in 1976 on a new frequency - DWGO 1008 kHz. SBC later added a sister station on the FM Band - DWOK 97.5 mHz, which began its regular operation on March 20, 1996. SBC soon acquired a franchise for radio and television operation, which began to broadcast regularly in January 2011 as DWAB TV 22 - the first free TV Channel in Olongapo City.
