Core Contents Media

Core Contents Media (코어콘텐츠미디어, CCM) was a South Korean entertainment label that operated from 2007 to 2014 as a subsidiary of Mnet Media under founder and producer Kim Kwang-soo. Originally established in 1999 as GM Planning, the company was absorbed into CJ Group via Mnet Media in 2006 before relaunching under the Core Contents Media name in 2007. The label became one of the defining forces in 2nd generation K-pop, with its roster anchored by ballad trio SeeYa, vocal duo Davichi, and girl group T-ara.

SeeYa joined the label through the Mnet Media absorption and found chart dominance quickly, winning Best Female Group at the 2007 Mnet Asian Music Awards on the strength of hit single Love's Greetings. Davichi debuted in 2008 and became one of the most consistent ballad acts in Korean pop. T-ara debuted in 2009 and spent the next several years as one of Korea's top girl groups, generating international fans across Asia. The label expanded further with Coed School (2010), 5Dolls (2012), SPEED (2012), and The SeeYa (2012), a successor group assembled after Nam Gyu-ri departed from the original SeeYa lineup in 2009.

Kim Kwang-soo was removed from Mnet Media's board of directors in September 2009 and effectively broke the company's relationship with Mnet Media, leaving Core Contents Media operating independently for the remainder of its run. On October 1, 2014, the label was acquired by MBK Co., Ltd. and rebranded as MBK Entertainment. MBK subsequently debuted DIA (2015) before the label closed in 2022, with its remaining artists transferred to PocketDol Studio.
