Samsung Electronics

Samsung Electronics Co., Ltd. (Korean: 삼성전자; Hanja: 三星電子 (Literally "tristar electronics")) is a South Korean multinational electronics company headquartered in Suwon, South Korea. Through having an extremely complicated ownership structure with some circular ownership, it is the flagship company of the Samsung Group, accounting for 70% of the group's revenue in 2012. Samsung Electronics has assembly plants and sales networks in 80 countries and employs around 308,745 people. It is the world's largest information technology company, consumer electronics maker and chipmaker by revenue. As of October 2017, Samsung Electronics' market cap stood at US$372.0 billion. Samsung has long been a major manufacturer of electronic components such as lithium-ion batteries, semiconductors, chips, flash memory and hard drive devices for clients such as Apple, Sony, HTC and Nokia. It is the world's largest manufacturer of mobile phones and smartphones, started with the original Samsung Solstice and later fueled by the popularity of its Samsung Galaxy line of devices. The company is also a major vendor of tablet computers, particularly its Android-powered Samsung Galaxy Tab collection, and is generally regarded as pioneering the phablet market through the Samsung Galaxy Note family of devices. Samsung has been the world's largest television manufacturer since 2006, and the world's largest manufacturer of mobile phones since 2011. It is also the world's largest memory chips manufacturer. In July 2017, Samsung Electronics overtook Intel as the largest semiconductor chip maker in the world. Samsung, like many other South Korean family-run chaebols, has been criticized for low dividend payouts and other governance practices that favor controlling shareholders at the expense of ordinary investors. In 2012, Kwon Oh-hyun was appointed the company's CEO but announced in October 2017 that he would resign in March 2018, citing an "unprecedented crisis".
