DZBB (pronounced DZ-double-B; 594 kHz AM), broadcasting as GMA Super Radyo DZBB 594, is a 24/7 news-talkradio station based in Diliman, Quezon City, Philippines, aimed at the Mega Manila market. It is the flagship station of the Super Radyo Stations. It is a part 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 Double B 580 (1950–1989)
DZBB was established 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 kilocycles.
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, music and entertainment programming. 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.
As DZBB Bisig Bayan 594 (1989–1999)
The station was known 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 and Helen Vela were the personalities of the Bisig Bayan format.
As Super Radyo DZBB 594 (1999–present)
On January 4, 1999, the station was renamed "Super Radyo DZBB 594". 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, Balitanghali, and Celebri-TV.
In 2010, for the first time in Philippine radio history, DZBB and its rival station DZMM of ABS-CBN made a historical simulcast. 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. 
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 blow-by-blow boxing coverage, especially during Manny Pacquiao's fights (alongside Barangay LS 97.1 and Radio GMA AM and FM stations nationwide) and other major boxing fights (dubbed as Laban ng Lahi). As such, DZBB became the first radio station to do so.
