SB19's history begins in 2016 when they were formed by ShowBT Philippines, the local subsidiary of South Korean ​entertainment company ShowBT Group. The group's members—Josh, Pablo (formerly Sejun), Stell, Ken, and Justin—​were selected through auditions aimed at discovering talents for the K-pop style training system. Initially intended for ​company events, they were later launched as a boy group under the decision of former CEO Geong Seong Han.

In October 26 2018, SB19 officially debuted with the ballad single "Tilaluha". Despite modest initial success, their ​breakthrough came in 2019 with the release of "Go Up". This single gained significant attention after a fan-uploaded ​dance practice video went viral on social media platforms like Twitter and Facebook. This unexpected surge in ​popularity propelled them into mainstream awareness, leading to appearances on various radio and television programs ​both locally and internationally.

Throughout the end of 2019 and the beginning of 2020, SB19 embarked on their first nationwide concert tour titled ​‘SB19: Get in the Zone’, expanding their fanbase and solidifying their presence in the Philippine music scene. Their ​achievements that year included becoming the first Filipino act to appear on the Billboard Next Big Sound chart and ​entering the Billboard Social 50, peaking at No. 2 in August 2020, highlighting their growing international appeal.

In 2020, SB19 continued to build on their success with their debut album "Get In The Zone", which featured popular ​tracks like "Go Up" and "Alab (Burning)". They also achieved notable positions on Billboard charts, further establishing ​their position as a rising force in the global music industry.

The years 2021 and 2022 saw SB19's expansion into new territories with releases like their extended play "Pagsibol" and ​singles such as "What?" and "Bazinga", the latter of which made history by debuting on Billboard's Hot Trending Songs ​chart. They also made significant cultural impacts as ambassadors for the National Commission for Culture and the Arts ​and through international performances.

In 2023, SB19 formally announced the establishment of their independent label, 1Z Entertainment, marking a new chapter ​in their career. They released the EP "Pagtatag!" and announced a global tour, showcasing their continued evolution and ​commitment to their artistic vision. "GENTO", the lead track from the EP debuted strongly on the Billboard World ​Digital Song Sales chart, entering at No. 8. This achievement marked SB19's first top 10 placement on this prestigious ​chart, showcasing their increasing global appeal and solidifying their presence in the international music scene. The ​GENTO era of SB19 underscores their international appeal, marked by their selection to perform at the 2023 Asia Artist ​Awards. They also headlined several music festivals, including the Aurora Music Festival 2024 in Pampanga and a few ​other international events: the Round: ASEAN–Korea Music Festival 2023 and Playlist Live Festival 2023 in Indonesia, ​and Pistang Pinoy sa Korea 2024 in South Korea.

Overall, SB19's history is characterized by their journey from being local talents to becoming trailblazers in the ​Philippine music industry.
