As News at 7 Davao (1979-93) The first GMA Davao newscast, named
News at 7 Davao brought the first newscast in Southern Mindanao that aired in 1979.
Southern Broadcasting Network Davao's newscast was aired locally. The newscast last aired in 1993.
As Testigo (1999-2014) Its main newscaster is Tek Ocampo; he started with Testigo (first named Testigo: GMA Super Balita) on October 4, 1999, and made a name as a national reporter for GMA News when he left the show in 2002. After his stint with GMA Manila, he returned to Davao to anchor the program again. To strengthen the regional network's commitment of bringing the latest, most credible and most comprehensive news from the region, in February 2013, the newscast started its international broadcast on
GMA News TV International alongside other regional newscasts
Balitang Amianan (now
One North Central Luzon) and
Balitang Bisdak. Testigo ended its 15-year run on November 7, 2014.
As 24 Oras Southern Mindanao (2014-2016) On November 10, 2014, the newscast adopted the branding of its now-main newscast
24 Oras as
24 Oras Southern Mindanao, following their change of graphics and theme music of the network's flagship newscast of the same name. On February 1, 2016, this program became the only GMA regional newscast to use the
24 Oras branding after two of its other regional newscasts reverted back to their original names,
Balitang Amianan (now One North Central Luzon) and
Balitang Bisdak (since 1999).
As 24 Oras Davao (2016-2017) On October 3, 2016, 24 Oras Southern Mindanao changed once again its branding simply as
24 Oras Davao. The rebranding coincided to the 17th anniversary of the regional network's news department alongside
GMA Cebu's
Balitang Bisdak, as well as expanding out the coverage of
GMA Dagupan's
Balitang Amianan. On January 2, 2017, the newscast updated its opening billboard, soundtrack, and lower third graphics similar to 24 Oras, together with other sister newscasts
Balitang Amianan and
Balitang Bisdak. On April 17, 2017, senior correspondent Real Sorroche was promoted as anchor of the newscast, with the launch of his segment
Usapang Real.
As GMA Regional TV One Mindanao (2017–present) After 24 Oras Davao, GMA Regional TV launched a news program covering the entire Mindanao island called
GMA Regional TV One Mindanao. The newscast is also considered the successor for other news programs produced by GMA for Mindanao, namely
24 Oras Northern Mindanao (formerly Testigo Northern Mindanao, from 2013 to 2015) of GMA Northern Mindanao and
Soccksargen Isyu Karon (from 2010 to 2011) and
Flash Bulletin (from 2010 to 2015) of GMA General Santos. At the same time, GMA Cagayan de Oro reopened its studios with former relief anchor and correspondent Clyde Macascas (later replaced by Cyril Chaves, Ethel Ipanag and James Paolo Yap), which is used by the newscast. Before the launch of its studio, reports and headlines from Cagayan de Oro and the rest of Northern Mindanao and Caraga are aired live from the GMA Cagayan de Oro Control Room. The Zamboanga, Sulu, Butuan, Kidapawan, Cotabato, Surigao, and Tandag stations were formerly direct satellite stations to
GMA-7 Manila before being reassigned as relays to GMA Davao since August 28, 2017. From Soccsksargen, BARMM, and Zamboanga Peninsula (including Zamboanga City), the newscast brings reports and headlines, the only one used
Cebuano and
Filipino for the Mindanaoan newscast from August 28, 2017, to November 24, 2019, now switched to full Cebuano language on November 25, 2019. On May 6, 2019, the newscast unveiled a minor revision of its title card, changing its font color to green, reflecting its co-produced
GMA Regional TV Weekend News (later
Regional TV Weekend News, now
Regional TV News), which was launched on May 11. One Mindanao was relaunched on May 6, 2019, adopting graphics and studio sets for Davao and Cagayan de Oro stations from the national newscast. In addition, the program opens its doors for viewers to become its live studio audience every Friday, similar to its sister regional newscast
GMA Regional TV Balitang Bisdak. Real Sorroche was last seen anchoring the newscast on July 1, 2021, and later eventually left the newscast on the same year for unknown reasons. Tek Ocampo left the newscast on September 17, 2021, to run for politics and was elected as City Councilor of the 1st District of Davao City. Co-anchors and correspondents Jandi Esteban, Cyril Chaves, and Rgil Relator joined Hilomen-Velasco in the anchor team on September 20, 2021, all taking turns anchoring the newscast, using the two-anchor format that the other regional newscasts adopted. The program started using the newly inaugurated and opened studios of the GMA General Santos Station on March 14, 2022, and the GMA Zamboanga Station on March 27, 2022, now in tandem with the GMA Cagayan de Oro Station and GMA Davao Station. Co-anchors and news producers Efren Mamac (Thursday co-anchor) and Jestoni Jumamil (Tuesday co-anchor) were added to the newscast's roster of anchors on May 1, 2022, until August 4, 2024, making the newscast the first GMA Regional TV newscast to adopt the 4-anchor format, albeit the anchors taking turns in anchoring the newscast. On August 4, 2024, co-anchor & correspondent Jestoni Jumamil announced that he would be having his final appearance as the program's anchor, leaving Hilomen-Velasco, Chaves, & Mamac as the remaining anchors for the newscast. On August 30, 2024, Krissa Dapitan marked her final appearance. Three days later, on September 2, 2024, the newscast tweaked a major revision of its title card. It changed its font color to blue, removed the logo for GMA Regional TV, and changed the graphics and OBB to reflect it under GMA Integrated News and GMA News Online. 28 days later, on September 30, 2024, the GMA Integrated News OBB replaced the GMA Regional TV's own OBB. The display of the headlines is also changed, with the main headline serving as the title and the program's name serving as the subtitle. With this change, Chaves and Mamac have been alternating as Hilomen-Velasco's co-anchor, and Mamac moved to the General Santos bureau. On May 9, 2025, the OBB changed, and Al Torres officially retired, being replaced by Weng dela Peña. On September 29, 2025, the news program became available via livestream on GMA Regional TV's social media accounts, alongside
Balitang Bisdak,
One Western Visayas, and
One North Central Luzon. ==Anchors==
