SK Broadband, formerly known as Hanaro Telecom, is a privately owned telecommunications company headquartered in South Korea and a wholly owned subsidiary of SK Telecom. Founded in 1997, the company operates with approximately 280 employees and reported $3.2B in revenue as of 2024, functioning as a tier 1 media tech buyer. It specializes in telecoms and is one of the broadband Internet access providers in South Korea. Until its takeover in 2008, Hanaro controlled nearly half of the Korean landline market, as it was the only last mile-competitive local exchange carrier (CLEC) other than the state-owned KT Corp. SK Broadband also has a division known as "Broad &" that controls a large portion of the South Korean calling card market.
On September 18, SK Broadband obtained the "2026 Best HRD" certification, a government-sponsored national recognition for its "talent-centered management" performance in human resource management and development, jointly organized by the Ministry of Employment and Labor, the Ministry of Education, the Ministry of Trade Industry and Energy, and the Ministry of Small and Medium Venture Business. This development follows a period of significant internal discussion, as the company's union on September 10 demanded a new growth strategy and funding commitments related to plans to separate SKB's data center and proprietary submarine cable-based international leased-line businesses into a new entity, SK Horizon. Under the proposed restructuring, scheduled for February 1, 2027, SK Horizon will take over these businesses while SKB remains the surviving company. Earlier, on September 9, the SK Broadband labor union denounced this data center spin-off, vowing to block the plan. Previously, on September 3, SK Broadband announced its "AI 5" set-top box achieved a "grand slam," winning all four of the world’s major product design awards.
