Just one year after its 1997 foundation, the company launched its first game, Lineage, after which it turned into the world's top online game company.

Today, NCSoft has expanded beyond the boundaries of South Korea opening subsidiaries in the U.S.A., Thailand, Japan, China and England. With around 3,000 employees, the company has estimated revenues of $686.6 million (2012). Reportedly, Kim Tack-Jin sold 25% of his stake at Nexon in June 2012. That earned him $685 million and left him approximately 10% of the company's stakes.
