D-12-ZB-TV (channel 12) is a television station in Batangas City, Philippines, airing programming from the GMA network. It is owned and operated by the network's namesake corporate parent alongside GTV outlet DZDK-TV (channel 26). D-12-ZB-TV's analog and Digital transmitter are located atop Mt. Banoy, and the Digital SFN relay transmitting towers are located at Barangay San Jose, San Pablo, Laguna.
In 2021, GMA Batangas started planning to upgrade as a new originating TV station. In 2022, GMA revealed the name of the flagship Filipino-language newscast of GMA Batangas, which it had launched on February 14, 2022, entitled "Balitang Southern Tagalog".[1] [2]
On, due to cost-cutting measures, GMA Batangas, along with GMA Naga, was downgraded into a relay (satellite-selling station) and Balitang Southern Tagalog aired its final broadcast for more than 2 years.
