One North Central Luzon

One North Central Luzon (also known as GMA Regional TV One North Central Luzon; previously known as 24 Oras North Central Luzon, 24 Oras Amianan and Balitang Amianan) is a Philippine news program of the GMA Regional TV in the North Central Luzon super region. The newscast delivers news and current affairs in Tagalog language. The news program is the first regional news program of GMA to be delivered in Tagalog, and the first in Luzon. Initially created to deliver news from North Central Luzon, the newscast expanded its coverage into Ilocos Region, Cordillera Administrative Region, Cagayan Valley and parts of Central Luzon as part of GMA Regional's plans to strengthen its local news division. Originally anchored by Jorge Guerrero, it premiered on May 5, 2008. Cris Zuñiga currently serves as the main anchor.

The newscast airs from Monday to Friday from 5:10 PM to 5:40 PM on GMA Dagupan (TV-10), GMA TV-5 Ilocos Norte, GMA TV-48 Ilocos Sur, GMA TV-7 Abra, GMA TV-5 Mountain Province, GMA TV-7 Tuguegarao, GMA TV-13 Aparri, GMA TV-7 Isabela, GMA TV-5 Baler, GMA TV-7 Batanes and GMA TV-10 Olongapo.

Balitang Amianan was also re-aired for national viewers under GTV's late night block "Local News Matters: GMA Regional TV Strip" on a weekly basis. It aired every Monday at 11:50 PM from May 18, 2020 to July 19, 2021.

The program also airs worldwide on GMA News TV.

As Balitang Amianan (2008–2014)
It first aired on Channel 10 in Dagupan and anchored by former anchor for TV Patrol North Central Luzon/TV Patrol Ilocos (now TV Patrol North Luzon) and Dateline Northern Luzon (now defunct) Jorge Guerrero and the first set of news reporters namely Joyce Segui, CJ Torida, Alfie Tulagan and Charisse Victorio. In June 2012, Jorge Guerrero left the show and moved to GMA Ilocos to become the solo anchor of Balitang Ilokano (later 24 Oras Ilokano) and was replaced by CJ Torida. Co-anchor and reporter Joyce Segui joins Torida on the anchor team in 2013. The channel's biggest expose so far is about a casino which was established in Poro, San Fernando, La Union.

On June 7, 2010, the newscast updated its opening billboard, graphics, together with other newscasts 'Balitang Bisdak'(GMA Cebu), 'Ratsada' (now One Western Visayas)' (GMA Iloilo and Bacolod) and 'Testigo' (now One Mindanao)' (GMA Davao); but just editing the music in the video editor like the 1979 hit 'Escape' by Rupert Holmes,in performance of Midnight Special/Don Kirshner's Rock Concert

To strengthen its commitment of bringing the latest, most credible and most comprehensive news from the region, in July 2013, Balitang Amianan started its international broadcast on GMA News TV International alongside other newscasts Balitang Bisdak and 24 Oras Davao (now One Mindanao).

The newscast's first incarnation ended its 6-year run on November 7, 2014.

As 24 Oras North Central Luzon/24 Oras Amianan (2014–2016)
Following changes of its now-main newscast 24 Oras, Balitang Amianan was rebranded as 24 Oras North Central Luzon effective November 10, 2014.

On August 31, 2015, 24 Oras North Central Luzon retitled as 24 Oras Amianan (after Ratsada 24 Oras of GMA Iloilo since July 20, now relaunched since August 27, 2018 as One Western Visayas) with an additional segment called "Trivia ni Araguy". 24 Oras Amianan aired its last telecast on January 29, 2016.

As GMA Regional TV Balitang Amianan (2016–2022)
On February 1, 2016, GMA Regional TV Balitang Amianan returned on the air after more than a year hiatus. On April 18, 2016, Faye Centeno joined as Torida's co-anchor in the newscast.

Since October 3, 2016, GMA Regional TV Balitang Amianan started its simulcast on GMA TV-5 Ilocos Norte, GMA TV-48 Ilocos Sur, GMA TV-7 Abra and GMA TV-5 Mountain Province as it expands its coverage area to the northern areas of the Ilocos Region and some parts of the Cordillera Administrative Region and Central Luzon (Balitang Amianan already broadcast in selected areas of Central Luzon [ Tarlac, majority Tagalog-speaking provinces of Nueva Ecija and Zambales, and selected areas of Pampanga, Bulacan, and Aurora in particular] in the beginning of news program, which is the reason for using the Filipino language as its medium); Central Luzon is a multicultural & multilingual region, with Tagalog/Filipino serving as a regional lingua franca & Ilocano as a main lingua franca in the northern areas of the region.

On January 2, 2017, the newscast updated its opening billboard and lower third graphics similar to 24 Oras, together with other newscasts GMA Regional TV Balitang Bisdak and GMA Regional TV One Mindanao.

Relaunch
On October 23, 2017, Balitang Amianan relaunched with a brand new set and segments (including the well-known Anto Tan?), as well as theme music and OBB, similar to its sister regional news program One Mindanao, GMA Regional TV's newscast for Mindanao stations, which was launched two months earlier. Longtime correspondent Joanne Ponsoy joined Torida and Centeno to anchor the newscast.

In July 2018, longtime reporter Jasmin Gabriel-Galban joined Torida and Ponsoy on the anchor team. She replaced Faye Centeno, who left the newscast.

On July 29, 2019, the newscast tweaks a minor revision of its titlecard, changing its font color to green, reflecting it with its co-produced national newscast GMA Regional TV Weekend News (later Regional TV Weekend News, now Regional TV News), which was launched on July 27. A week after, on August 5, 2019, Balitang Amianan updated their graphics and introduced new opening titles patterned with its co-produced national newscast (featuring the sceneries of the program's coverage area). The newscast had a more relaxed set-up with couches instead of the tables and chairs that viewers usually see on typical newscasts intending to be an extension of viewers' living room, further connecting the news anchors and the viewers.

On 2020, Balitang Amianan temporarily relayed its broadcast to GMA Bicol Region stations before the formal launch of Balitang Bicolandia: GMA TV-7 Camarines Sur, GMA TV-12 Albay, GMA TV-2 Sorsogon, & GMA TV-13 Catanduanes.

On March 15, 2021, Balitang Amianan expands its simulcast on GMA TV-7 Tuguegarao, GMA TV-13 Aparri, GMA TV-7 Isabela, GMA TV-5 Baler, GMA TV-7 Batanes, and GMA TV-10 Olongapo as it expands its coverage area to Batanes, Cagayan, Isabela, Nueva Vizcaya, Quirino, and other majority native Tagalog-speaking provinces of Aurora and Zambales; Balitang Amianan already aired in selected areas of Aurora & Zambales at the start of the news program, as those areas were reached by the airwaves of GMA-10 Dagupan. GMA Tuguegarao, GMA Aparri, GMA Isabela, GMA Baler, GMA TV-7 Batanes, and GMA Olongapo were former relay stations of GMA-7 Manila before being reassigned to GMA Dagupan on March 15, 2021. Three months later, on June 14, 2021, Balitang Amianan updated its opening billboard to reflect the addition of Cagayan Valley and the rest of Cordillera and Central Luzon (except for Bataan and Bulacan) to its coverage area.

From September 20 to November 19, 2021, Torida temporarily left the newscast while Gabriel-Galban returned to being a field reporter, leaving Ponsoy as a solo anchor until Torida returned. Co-anchor and Mornings with GMA Regional TV host Harold Reyes replaced Gabriel-Galban in the anchor team from February 25, 2022 to June 30, 2023, once again reviving the three-anchor format for the newscast and three other regional newscasts.

The newscast started using the newly opened studio of the GMA Ilocos Sur Station on April 25, while in tandem also using the studio of the GMA Dagupan Station. Co-anchor-correspondent Ivy Hernando joined the anchor team on June 10, 2022.

As GMA Regional TV One North Central Luzon (2022-present)
On September 5, 2022, the newscast was rebranded to "GMA Regional TV One North Central Luzon" as part of the newscast expanding its coverage to other Tagalog-speaking provinces of Bataan and Bulacan, being the third newscast to use the ONE brand, alongside One Mindanao from GMA Davao, GMA Cagayan de Oro, GMA Zamboanga and GMA General Santos and One Western Visayas from GMA Bacolod and GMA Iloilo.

Less than a year after the relaunch, the program started using the studio of the GMA Ilocos Norte Station on March 6, 2023. Co-anchor Breves Bulsao from PTV Cordillera joined the anchor team on May 24, 2023, making the newscast to be the first among other GMA Regional TV programs to adopt the 5-anchor format.

Anchor and former TV Patrol North Central Luzon (later TV Patrol North Luzon) anchor and correspondent Cris Zuñiga solely took over the newscast on July 26, 2023. Torida and Ponsoy had their last appearance as anchors the day before, transferring to the morning newscast Mornings with GMA Regional TV; this ended hosting of CJ Torida of the news program for 11 years. Harold Reyes and Breves Bulsao left the network while Ivy Hernando returned to being a field reporter. Zuñiga made his first national appearance in Regional TV News on July 31, 2023.
