KT Corporation
South Korean telecommunication service provider
KT Corporation (Hangul: 주식회사 케이티), formerly Korea Telecom, is a South Korean telecommunications company, mobile network operator (MNO) and mobile virtual network operator (MVNO). KT is the large wireless carrier in South Korea, with 13.5 million subscribers as of Q4 2023.
The formerly fully-state-owned firm (the government's National Pension Service currently owns 12.19% shares and is the largest shareholder) is South Korea's first telecommunications company and is a major supplier of the local landline and broadband internet market, serving about 90 percent of the country's fixed-line subscribers and 45 percent of high-speed Internet users. After selling its wireless affiliate Korea Mobile Telecom in 1994, KT returned to the wireless market with the creation of PCS carrier KTF in January 1997.
The company's merger with KTF, its wireless subsidiary, in 2009 made it the country's ninth largest chaebol (conglomerate) with nearly 24 trillion won in assets as of 2009.
In January 2011, KT launched unified brand "Olleh" for both fixed-line and cellular broadband services. However in 2016, they decided to revert to "KT" for landline and cellular broadband services.
Company overview
Founded in 1981 as a public utility, KT played a major role in Korea's development in the information technology hub sector. KT sold its wireless affiliate in 1994, founding another in 1996 and becoming, along with LG Dacom, one of Korea's earliest Internet service providers. In 2001 KT acquired struggling broadband provider Thrunet, then the largest broadband company in Korea, which paved the way for KT to dominate the broadband market.

Why this record matters
A short description can identify a subject without explaining its stakes. For “KT Corporation”, the useful work is to connect “south Korean telecommunication service provider” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 9, 2026. The linked authority identifier is Q485908. 2 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2023, 1994, 1997 and 2009.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
