Samsung was founded by Lee Byung-chul in 1938 as a trading company. Over the next three decades, the group diversified into areas including food processing, textiles, insurance, securities and retail. Samsung entered the electronics industry in the late 1960s and the construction and shipbuilding industries in the mid-1970s; these areas would drive its subsequent growth. Following Lee's death in 1987, Samsung was separated into four business groups�� Samsung Group, Shinsegae Group, CJ Group and Hansol Group. Since 1990, Samsung has increasingly globalised its activities and electronics; in particular, its mobile phones and semiconductors have become its most important source of income.

LG Corp. established as Lak-Hui Chemical Industrial Corp. in 1947.[3] In 1952, Lak-Hui (pronounced "Lucky", currently LG Chem) became the first South Korean company to enter the plastics industry. As the company expanded its plastic business, it established GoldStar Co. Ltd. (currently LG Electronics Inc.) In 1958, both companies Lucky and GoldStar merged and formed Lucky-GoldStar.
GoldStar produced South Korea's first radio. Many consumer electronics were sold under the brand name GoldStar, while some other household products (not available outside South Korea) were sold under the brand name of Lucky. The Lucky brand was famous for hygiene products such as soaps and HiTi laundry detergents, but the brand was mostly associated with its Lucky and Perioe toothpaste. Even today, LG continues to manufacture some of these products for the South Korean market, such as laundry detergent.
In 1995, to compete better in the Western market, the Lucky-GoldStar Corporation was renamed "LG". The company also associates the letters LG with the company's tagline "Life's Good". Since 2009, LG has owned the domain name LG.com.
