[1] DZBB-TV traces its history to Metro Manila radio station DZBB, owned by Loreto F. de Hemedes, Inc.,[2] later renamed Republic Broadcasting System, Inc. of Robert "Uncle Bob" Stewart.

[3] In 1974, RBS, including its TV and radio stations, were sold to a triumvirate composed of Felipe Gozon, Gilberto Duavit Sr., and Menardo Jimenez who introduced a programming concept catering to the new audience.

The political instability of the country also added to the station's burden, when soldiers stormed into its studios for two days as part of a coup attempt to topple then President Corazon Aquino.

Known as the "Tower of Power", which initially operated on a 50 kilowatt transmitting output from 1988 to 1998, the 777 ft (236.8 m) transmitter helped improve the channel's reception in Luzon, and was also the tallest man-made structure in the country at the time.

According to a December 2017 press release, the station's upgraded signal transmission covered the areas of Metro Manila, Rizal, Cavite, Laguna, Bulacan and parts of Pampanga, Bataan, Nueva Ecija and Batangas.

In 2018, National Telecommunications Commission released implementing rules and regulations on the re-allocation of the UHF Channels 14-20 (470–512 Megahertz (MHz) band) for digital terrestrial television broadcasting (DTTB) service.
