Many major South Korean corporation such as CJ Corporation, Shinsegae department store and Joong-Ang Ilbo daily newspaper were previously part of the Samsung Group, split apart by the government in order to reduce its power. Many leading companies in South Korea, notably iriver, the No.1 MP3 Player maker in South Korea and Naver, the No.1 Search Engine portal in South Korea, were established by ex-Samsung employees. A large number of South Korean firms, particularly those in the electronics industry, are dependent on Samsung for the supply of vital components or raw materials such as semiconductor chips or LCD panels. Consequently, Samsung is able to artifically moderate prices and has been criticised for handicapping other rivals, leading to bankruptcy of mid to small sized businesses as they cannot compete with Samsung. As a result, many have been taken over by Samsung Group, leading to a complete dominance by Samsung Group in many industries.

Samsung Group accounts for more than 20% of South Korea's total exports, with strong government support, including the ability to access unlimited amount of funds from major banks in South Korea. In many domestic industries, Samsung Group is the sole monopoly dominating a single market, its revenue as large as some developing countries' total GDP. The company owns or has taken over so many mid to small sized businesses that it is often called a 'colonial empire' or 'hungry dinosaur'. The company has a powerful influence on the country's economic development, politics, media and culture, being a major driving force behind the Miracle on the Han River. Many Koreans consider Samsung Group a symbol of national pride and businesses use its international success as a model, with the company being known as "Another Family" in South Korea.
