Commonwealth and Third Republic

On May 8, 1933, the United States-sponsored Insular Government established and operated radio station DZFM (then KZFM) in the Philippines on the frequency of 710 kilohertz with a power of 10,000 watts through the United States Information Service. In 1944, during the liberation campaign. In September 1946, two months after the restoration of Philippine independence thru the Treaty of Manila, KZFM was turned over to the Philippine government. With the transfer was born the Philippine Broadcasting Service (PBS), the second broadcasting organization after Manila Broadcasting Company (now MBC Media Group).

KZFM first operated under the Department of Foreign Affairs until it was transferred to the Radio Broadcasting Board (RBB), created by President Manuel Quezon on September 3, 1937. In 1947, an International Telecommunications Conference in Atlantic City, New Jersey, assigned the letter "D" to replace "K" as the first call letter for all radio stations in the Philippines. On January 1, 1952, the RBB was abolished to give way to the establishment of the Philippine Information Council (PIC) which assumed the function of the RBB, including the operation of DZFM. On July 1, 1952, after the PIC was abolished, DZFM and the Philippine Broadcasting Service (PBS) operated under the Office of the President. In 1959, the both were placed under the newly created Department of Public Information (DPI).

Years hence, the PBS acquired 13 more radio stations, one TV station, DZFM-TV Channel 10 which it time-shared with two other organizations, and changed its name to Bureau of Broadcast Services. September 13 is marked as the anniversary of the PBS.

In the 1960s, PBS' radio network expanded to the key provinces with DZEQ in Baguio, DYMR in Cebu, DYCI in Iloilo, DXRP in Davao and DZMQ in Dagupan.

Martial law and into the Fifth Republic

At the same time that the BBS creating its network, another government organization was building up its broadcast capability to rival, or in some instances, complement, that of the BBS. The National Media Production Center (NMPC) had acquired the facilities of Voice of America in Malolos, Bulacan in 1965 and steadily brought the old complex up to standards by a steady overhaul, fine-tuning, and outright replacement of outmoded equipment and machines. The NMPC operated the “Voice of the Philippines” (VOP), on both medium wave-920 kHz and shortwave 9.810 mHz transmissions. In 1975, the NMPC obtained DZRB-FM. With this new station and some provincial stations that came under its wings earlier, the NMPC was a network and effectively covered a wide range of the Philippine listenership.

In the 1970s, public broadcasting in the Philippines was thus represented by the BBS and the NMPC and catered to the educational and cultural needs of its audiences while endeavoring to keep it entertained with fare from indigenous material. Public service features were the keystone of its programs.

During the final months of Martial Law, both the BB and the NMPC were brought under one administrative roof in 1980 when the Office of Media Affairs was created to provide a loose union for both networks within the Broadcast Plaza along Bohol (now Sgt. Esguerra) Avenue in Diliman, Quezon City. It was not an ideal situation, since, as there had been no clear guidelines on the proper implementation of their respective operational strategies, the BB and the NMPC often squabbled, to the detriment of public broadcasting goals. Unification had created more problems for the OMA to overcome.

After the EDSA Revolution, the Office of Media Affairs was abolished, followed by both the NMPC and the BB. Under Executive Order No. 297, on the basis of the OMA, President Corazon Aquino reestablished the Bureau of Broadcast Services (BBS) and reinstated PBS as the network under the Office of the Press Secretary's control, which led to the formation of a national radio service based on the stations in which both the NMPC and BBS had, with the PBS hosting two national AM stations and a national FM station in Manila and a number of provincial owned-and-operated and affiliate stations in the country's administrative regions.

During the last months of the Aquino administration, PBS along with its TV counterpart, People's Television Network transferred its offices from ABS-CBN Broadcasting Center complex to PIA/Media Center Building in Visayas Avenue, Quezon City on January 22, 1992.

On January 2, 1995, PBS relaunched its flagship station (DZFM) as Radyo ng Bayan.

During the first years in the administration of President Benigno Aquino III, the PBS-BBS was transferred to the newly created Presidential Communications Operations Office (PCOO), after the OPS was abolished.

In the beginning of 2017, PBS relaunched its FM radio service with the relaunch of FM2 and the debut of FM1 as well, forming the basis of the national FM radio division under the agency, which was later reinforced by the launch of FM1 Davao, the first state-owned regional FM radio station serving Metro Davao.

On June 5, 2017, as part of the network's 70th anniversary, PBS relaunched its flagship brand Radyo ng Bayan as Radyo Pilipinas. Three months later, on September 18, sports station DZSR merged its programming with infotainment/cultural station DZRM and became Radyo Pilipinas Dos.

On July 16, 2018, PBS-BBS and the Global Satellite Technology Services Inc. (G Sat) signed a Memorandum of agreement allowing PBS-BBS to add its channels to its G Sat radio channel line up.^[2]

In October 2019, China donated over PHP130 million worth of radio broadcast equipment to the PCOO's Philippine Broadcasting Service (PBS). The donation includes live broadcast room equipment, FM broadcast transmitter equipment, and medium wave transmitter equipment. The Presidential Communications Operations Office (PCOO) will soon begin the rehabilitation of at least 14 (10 AM and four FM station) PBS Radyo Pilipinas stations nationwide.^{[3][4][needs update]} In 2021, the PBS welcomed a new network into the ranks - Radio Kidlat, a community radio network owned and operated by provincial electric cooperatives.

During his first State of the Nation Address, President Rodrigo Duterte announced that Congress would pass a proposed law merging the PBS with its TV counterpart, People's Television Network to form the "People's Broadcasting Corporation (PBC)", which serves a unified broadcasting entity of the republic encompassing radio, television, print and online media.

On April 10, 2023, DZRM officially rebranded as Radyo Pilipinas Tres which will serve as the country's public service station which aim's to give information for disaster preparedness, bulletins and updates, and information dissemination.

Under Executive Order No. 16 series of 2023 (Reorganizing the Presidential Communnications Office) issued in February 2023, the Philippine Broadcasting Service was renamed as the Presidential Broadcast Service - Bureau of Broadcast Services.^[5]
