DZBB (pronounced DZ-double-B; 594 kHz AM), broadcasting as GMA Super Radyo DZBB 594, is a 24/7 news-talk radio station based in Diliman, Quezon City, Philippines, serving Mega Manila and neighbouring provinces. It is the flagship station of the Super Radyo stations, and one of the assets of GMA News and Public Affairs, the news division owned by RGMA, a subsidiary of GMA Network Inc. The station's studio is located at the GMA Network Center, EDSA corner Timog Avenue, Diliman, Quezon City, while its transmitter is located at Barangay Panghulo, Obando, Bulacan.
As Dobol B 580/594 (1950–1989)
DZBB marked its inaugural broadcast, as the station's signal (although it was static marred) was wafted on the air for the first time on March 1, 1950 by Robert "Uncle Bob" Stewart, in a small office space in Calvo Building, Escolta, Manila with mostly second-hand equipment and an old, surplus radio transmitter. The station was then broadcasting on the frequency of 580 kHz.
Despite the scarcity of new broadcasting facilities, the station has scored many milestones with its news, senate and congress coverage, breaking news, exclusives, and blow-by-blow accounts of major national events. It also pioneered with trendsetting shows such as Camay Theater of the Air, Lovingly Yours, Helen, Kahapon Lamang, Tawag ng Tanghalan, Newscoop, and Kwentong Kutsero. Some of these shows eventually went to television. DZBB was also the first to air live coverage extended not just to news and public affairs, but also to entertainment and educational programs.
In 1957, DZBB moved to its new and current home at EDSA, Quezon City.
Due to the success of DZBB, Stewart ventured into television on October 29, 1961 as DZBB-TV Channel 7 with the branding of RBS-7 (now known as GMA-7 Manila). The station was seized and closed in September 1972 due to Martial Law. Two years later, Channel 7, DZBB and other provincial radio and television stations were eventually sold to the triumvirate of Gilberto Duavit, Sr., Menardo Jimenez and Felipe Gozon. At the same time, DZBB returned to the airwaves under the branding "Dobol B", and was a full service radio station with news, public service and entertainment programming. The station also covered important news coverages during the 70s and the 80s. In 1979, DZBB moved to the present frequency of 594 kHz, in response to the adoption of the 9 kHz spacing on AM radio stations in the Philippines under the Geneva Frequency Plan of 1975.
As DZBB Bisig Bayan 594 (1989–1999)
The station was rebranded as "Bisig Bayan" from July 17, 1989 to January 3, 1999. Their new identity made the station more popular to radio listeners in Metro Manila. Rafael "Paeng" Yabut, Bobby Guanzon, Lito Villarosa, Rene Jose, Rey Pacheco, Raul Virtudazo, Jimmy Gil, Arman Roque, Rose "Manang Rose" Clores, German Moreno, Inday Badiday, Helen Vela, Augusto Victa, and Pol Caguiat were the personalities of the Bisig Bayan years.
Also in the early 1990s, DZBB evolved into a 24-hour round-the-clock broadcasting service, in order to keep up with the pace of delivering news to its listeners, and came out with Kape at Balita, a morning news/commentary/talk show hosted by Bobby Guanzon and then GMA News reporter Jessica Soho in 1992, which expanded to television the same year.
As Super Radyo DZBB 594 (1999–present)
On January 4, 1999, the station was renamed "Super Radyo DZBB 594" and the transmitting facilities moved to a new 50,000 watt transmitter in Barangay Panghulo, Obando, Bulacan. Much of their programming focuses on news and current events, and it still simulcasts GMA and GMA News TV programs such as 24 Oras, Saksi and Balitanghali.
In 2010, for the first time in Philippine radio history, DZBB and its rival station DZMM of ABS-CBN made history as they joined forces in the name of public service. Two children named James and Jesus asked for help to find their missing parents named Pascual and Norma Bantillan from Bohol on a rival program on DZMM Aksyon Ngayon Global Patrol and were eventually reunited through DZBB's program Aksyon Oro Mismo.
In 2014, DZBB kept its winning streak in Mega Manila as it continued to lead rival stations in ratings, according to data from Nielsen Media Research. DZBB grabbed the lead in Mega Manila in June 2014 and has since sustained leadership in the area, which it repeated in 2017. 
In 2017, DZBB officially launched its first ever jingle for the station and its newly renovated radio booth, as well as the relaunch of Dobol B sa News TV, after 5 years of hiatus on television.
DZBB's programs are mostly news, current issues, and news analysis produced by the GMA News and Public Affairs department. Their morning radio shows were anchored mostly by news anchors and personalities from television.
The station also has a newscast entitled Super Balita, as well as a simulcast of news and public affairs programs of GMA Network.
On some occasions, DZBB would also air live and exclusive blow-by-blow boxing coverage, especially during Manny Pacquiao's fights (alongside Super Radyo stations nationwide). As such, DZBB became the first radio station to do so.
As of 2018 DZBB also live streams select programs on its official FB page.
