Samsung 55 Inch QE55Q60T UHD HDR QLED TV

The inch (symbol: in or ″) is a unit of length in the British Imperial and the United States customary systems of measurement. It is equal to ⁠1/36⁠ yard or ⁠1/12⁠ of a foot. Derived from the Roman uncia ("twelfth"), the word inch is also sometimes used to translate similar units in other measurement systems, usually understood as deriving from the width of the human thumb.

Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s the inch has been based on the metric system and defined as exactly 25.4 mm.

Samsung Group (Korean: 삼성; pronounced [samsʌŋ]; stylised as SΛMSUNG) is a South Korean multinational manufacturing conglomerate headquartered in the Samsung Town office complex in Seoul. The group consists of numerous affiliated businesses, most of which operate under the Samsung brand, and is the largest chaebol (business conglomerate) in South Korea. As of 2024, Samsung has the world's fifth-highest brand value.

Founded in 1938 by Lee Byung-chul as a trading company, Samsung diversified into various sectors, including food processing, textiles, insurance, securities, and retail, over the next three decades. In the late 1960s, Samsung entered the electronics industry, followed by the construction and shipbuilding sectors in the mid-1970s—areas that would fuel its future growth. After Lee died in 1987, Samsung was divided into five business groups: Samsung Group, Shinsegae Group, CJ Group, Hansol Group, and JoongAng Group.

Key affiliates of Samsung include Samsung Electronics, the world's largest information technology company, consumer electronics maker and chipmaker by 2017 revenues; Samsung Heavy Industries, the world's second-largest shipbuilder by 2010 revenues; and Samsung Engineering and Samsung C&T Corporation, ranked 13th and 36th among global construction companies, respectively. Other significant subsidiaries are Samsung Life Insurance, the 14th-largest life insurance company globally, Samsung Everland, operator of Everland Resort (South Korea's oldest theme park), and Cheil Worldwide, the world's 15th-largest advertising agency by 2012 revenues.
