What is the SK Founding Story?
The SK Group's journey began on April 8, 1953, with the establishment of Sunkyong Textiles Ltd. in Seoul, South Korea. Founded by Chey Jong-gun, the company's initial focus was on rebuilding the nation's textile industry after the Korean War.
The Genesis of an Industrial Giant
The SK Group's origins are rooted in the post-war era of South Korea, a period demanding significant industrial reconstruction. Chey Jong-gun's vision for Sunkyong Textiles Ltd. was instrumental in this national rebuilding effort.
- Founded on April 8, 1953, as Sunkyong Textiles Ltd.
- Acquired from the South Korean government as abandoned Japanese property.
- Focused on textile production as a foundational industry.
- Achieved a milestone in 1958 by producing Korea's first polyester fiber.
The company's early operations were built upon acquiring Sunkyong Textiles, which had been a joint venture between two Japanese firms and was subsequently taken over by the South Korean government. Chey Jong-gun's entrepreneurial spirit was driven by a desire to industrialize the war-torn country, and the textile sector was seen as a crucial starting point. This foundational business led to a significant achievement in 1958 when the company successfully manufactured Korea's first polyester fiber, marking a key moment in the nation's industrial development.
A notable point in the SK Group history is its rebranding in 1998 from Sunkyong Group to SK Group. This change, declared by the current chairman Chey Tae-won on January 5, 1998, was partly motivated by the perception of the original name among English speakers. The shift aimed to foster a more global identity and better reflect the company's commitment to its clients. The initial funding for the company's inception came from the acquisition of the textile mill, providing the capital necessary for its early growth and subsequent diversification, which has led to its current status as a major conglomerate with diverse interests, including telecommunications and semiconductors, as detailed in the Revenue Streams & Business Model of SK.

What Drove the Early Growth of SK?
The early growth of the SK company, then known as Sunkyong, was characterized by a deliberate strategy of vertical integration and diversification. This period laid the groundwork for its transformation into a major South Korean conglomerate.
Vertical Integration Strategy
In 1969, Sunkyong Fibers Ltd. began producing yarn, marking the start of its manufacturing operations. A significant strategic move was the establishment of Sunkyong Oil in 1973, initiating a 'From Petroleum to Fibers' integration plan to control the entire production supply chain.
Diversification Beyond Industry
Further diversifying its interests, the company acquired the Walkerhill Hotel in 1973. This expansion demonstrated an early willingness to move beyond its core industrial focus and explore new market segments.
Expansion into Energy Sector
The 1980s saw a major leap into the energy industry with the acquisition of a 50% stake and management control of Korea Oil Corporation in 1980, renamed Yukong. By 1985, Yukong's refinery capacity reached 345,000 barrels per day, solidifying its position as a key player in oil refining.
Entry into Telecommunications and Global Markets
The SK Group history includes a pivotal entry into telecommunications in June 1994 by acquiring a significant share in Korea Mobile Telecommunication Service, which evolved into SK Telecom in 1997, quickly becoming the leading mobile provider with a 50% market share. This era also marked the beginning of its international presence with the establishment of its first Beijing office in 1991, a key step in its global expansion history.
