D-5-AS-TV was launched upon the establishment of GMA Network's predecessor Loreto F. de Hemedes Inc., which founded by Robert "Uncle Bob" Stewart, an American war correspondent.

On September 21, 1972, following the declaration of martial law by then-President Ferdinand Marcos by the virtue of Proclamation 1081, which forced the Congress and media establishments including RBS to closed down, D-5-AS-TV was shut down.

On April 30, 1992, as part of the network's Rainbow Satellite Network launch, Channel 5 Ilocos Norte officially became a satellite station to bring live broadcasts of Manila-sourced national programming via DZBB-TV, GMA's flagship TV station in Manila, allowing it to viewers in the Ilocos Region, utilizes a new logo to correspond with the rebranding and a satellite-beaming rainbow in a multicolored striped based on the traditional scheme of red, orange, yellow, green, blue, indigo and violet, with GMA in a metallic form uses a San Serif Country Gothic Extra Bold and analogous gloominess of indigo as its fonts in the letters.

However, the newscast suddenly got cancelled on April 24, 2015 due to the strategic streamlining of regional operations of the network, hence GMA Ilocos closed down its originating station.

The Ilocos stations, as well as Abra and Mountain Province transmitters are reassigned to Dagupan relays and began simulcasting Balitang Amianan newscast on October 3, 2016 (which later relaunched as One North Central Luzon since September 5, 2022).
