Big Hit Entertainment 빅히트엔터테인먼트 was founded on February 1, 2005, by Bang Sihyuk.
The company signed the vocal trio 8Eight (Lee Hyun, Baek Chan, and Joo Hee) in 2007.
In 2010, Big Hit Entertainment and JYP Entertainment signed a joint management contract over the boy group 2AM. That year, Bang Sihyuk launched nationwide auditions and signed RM (formally known as Rap Monster), the first member of BTS.
In 2012, the company signed Lim Jeonghee. The girl group GLAM was formed as a collaboration between Source Music and Big Hit Entertainment. The group was active until 2014, when they disbanded due to controversy over one of the members, Kim Dahee, who was sentenced to prison following accusations of blackmail in relation to actor Lee Byunghun.
BTS debuted under Big Hit in 2013.
Following the end of the joint contract between Big Hit and JYP Entertainment in April 2014, three of the 2AM members returned to JYP, while Lee Changmin stayed with Big Hit in order to continue with his solo career and as part of the duo Homme. That year, 8Eight disbanded after Baek Chan and Joo Hee's contracts with Big Hit ended.
In May 2015, Signal Entertainment Group, a company specializing in artist management and television production, acquired Big Hit through a KR₩6 billion convertible bond. Signal also owns Better ENT, the agency founded by actor Song Seungheon, as well as another record label, Jungle Entertainment.
In May 2015, Lim Jeonghee parted ways with Big Hit Entertainment, following the expiration of her three-year contract with the agency.
In early 2017, Big Hit ended their stake relationship with Signal Entertainment Group. Big Hit issued a 6 billion won convertible bond to Signal Entertainment Group in 2015. After a year, Signal Entertainment Group made a full settlement of the bonds.
In February 2018, the duo Homme disbanded after Changmin's contract came to an end and he left the company to start his own agency. Lee Hyun continued on as a solo artist.
