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 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 23, 1972 then President Ferdinand Marcos declared 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.

When democracy in the Philippines was restored in the People Power Revolution in 1986, other radio and television stations began to air, some with their original owners. The political instability of the country also added to the station's burden, when soldiers stormed into its studios for two days in a part of coup attempt to topple then President Corazon Aquino. At around 6 PM, the Radio Veritas backup transmitter failed and the station went off the air. News and updates about the uprising were now carried on by announcer June Kiethley of DZRJ, renamed to DZBB or Radio Bandido. DZBB's headquarters were kept secret to prevent a repeat of what happened to Radio Veritas.
