The Heacock era

DZRH first went on air as KZRH on July 15, 1939,[4] after being founded by Samuel Gaches, the owner of H. E. Heacock Company, a department store company based in Escolta, Binondo, Manila. DZRH, which was then broadcasting on the frequency of 650 kHz, became the fourth commercial radio station in the Philippines and years later, it bought KZRC (now DYRC) from Isaac Beck in Cebu City. KZRH's radio broadcasts centered on musical, variety shows, comedy skits and short newscasts. Jazz and ballads became standard fare.

During the Second World War, the Imperial Japanese troops took over the stations, and KZRH was rebranded PIAM ("Philippine Islands AM"), becoming a tool for the Second Republic's propaganda.[5]

The birth and expansion of DZRH

After the War, three prominent businessmen—Maestro Frederico Elizalde and his brothers then-Ambassador JM and Manuel (also known as Don Manolo)—took over KZRH and KZRC. With the help of station manager Bertrand Silen, KZRH re-established its operations, this time at the Insular Life Building on Plaza Cervantes in Binondo, Manila. In June 1946, the Elizalde family established the new network as Manila Broadcasting Company.

KZRH returned to the airwaves under MBC on July 1, 1946, and first covering the live inauguration of President Manuel Roxas under its new republic. In 1948, after the international telecommunications conference in the United States where the Philippines changed its first letter to "D", KZRH changed its callsign to DZRH, and has been expanded to over 30 stations nationwide.

In 1949, DZRH began airing the first radio drama, Gulong ng Palad ("Wheel of Fortune"). Radio drama is one of the traditions of Philippine radio before the rise of television industry and continues until today this time on the FM band (only Ito ang Palad Ko, "This is my fate", one of the longest-running drama anthology series since 1973).

Martial Law and post-EDSA

In 1972, when then-President Ferdinand Marcos declared Martial Law, DZRH was temporarily closed for a few months. It was reopened but only under strict government censorship.[6] It was the only other time in DZRH’s history since the Second World War that the station's broadcast operations were interrupted.

In 1978, DZRH moved from 650 kHz to the current frequency at 666 kHz due to the switch of the Philippine AM dial from the NARBA-mandated 10 kHz spacing to the 9 kHz rule implemented by the Geneva Frequency Plan of 1975. In the same year, DZRH launched Operation Tulong ("Help"), a socio-civic organization that helps the people in time of need.

DZRH in February 1986 covered the controversial snap elections and the ensuing People Power Revolution that peacefully deposed President Marcos and installed President Corazon Aquino.

In 1989, DZRH celebrated its 50th golden anniversary by launching "50 Taon ng Radyo" ("50 years of radio") on Sunday, July 23, 1989. Ceremonies and events held at Rizal Memorial Stadium and Araneta Coliseum included parades, games, concerts, as well as outdoor and indoor fireworks displays.

In 1991, radio veteran Joe Taruc joined the station, where he hosted Damdaming Bayan which is now the longest-running public affairs program, as well as a morning newscast. Aside from being a newscaster, he was also became station manager, and later, Senior Vice-President until his death in September 2017.

In 1994, as part of their 55th anniversary, DZRH launched its own nationwide satellite radio broadcast reaching 97% of the Philippine populace. Thus, the slogan is "One Nation, One Station". It also bought some of the broadcast veterans such as Jay Sonza, Rey Langit and Ka Louie Beltran.


In October 2007, DZRH once again ventured into television broadcasting with the launch of DZRH RadyoVision (which is not related to the now defunct VHF TV station DZRH-TV Channel 11), which was renamed RHTV in 2008 and DZRH News Television in 2013. It is now known as DZRH News Television since 2013. The channel is currently being seen on Cignal Channel 18, SkyCable Channel 129, CableLink Channel 3 and some cable TV affiliates nationwide, and worldwide via livestreaming on their official website. It is also the first cable channel to broadcast via Facebook Live by mirroring the live stream of DZRH News Television to the Facebook servers.

In 2009, DZRH celebrated its 70th anniversary by launching of the "Fiesta Sitenta" as well as the launch of its first ever theme song for the station. In the final quarter of 2011, DZRH did changes in their programming line-up as well as the adoption of the new slogan "RH Agad!" ("RH right now"). In 2012, DZRH launched its new slogan, Ang Makabagong Bayanihan ("The Modern Spirit of Volunteerism") and also includes the theme song of the station.

DZRH celebrated its Diamond Jubilee on July 15, 2014 at the Manila Hotel with the launching of the coffee-table book and the special commemorative stamp courtesy of PhilPost.[7] In 2015, DZRH celebrated its 76th anniversary with the theme "76 Taon ng Balita at Serbisyo" ("76 years of News and Service"). In 2016, DZRH celebrated its 77th anniversary with the theme "77 Years: Serbisyong tapat sa inyo".


In 1985, DZRH revived its first logo with the yellow rectangle embedding the MBC Radio logo in the left, and the old DZRH wordmark set in red large Helvetica bold typeface.

In 2003, DZRH changed its new logo with the yellow rectangle with the DZRH News logo in the left set in Arial bold font, the DZRH wordmark set in large red Helvetica Bold remained and underneath the DZRH wordmark are the words No.1 set in smaller red Arial Bold font and the words Kaunaunahan sa Pilipinas set in medium green Arial Bold typeface.
