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 11, 2026, South Korea's international submarine cables were found to be less than one-third the capacity of Japan's, raising concerns about the vulnerability of international communication networks linking domestic AI data centers to overseas facilities amidst intensifying competition for AI infrastructure. Previously, on September 10, the SK Broadband (SKB) union demanded a new growth strategy and funding commitments following plans to separate the company's data center and submarine cable businesses into a new entity, SK Horizon. This proposed restructuring, scheduled for February 1, 2027, would see SK Horizon taking over SKB's data center and proprietary submarine cable-based international leased-line businesses, with SKB remaining as the surviving company; the union had previously pushed back against this spin-off. Earlier, on September 2, SK Broadband announced that its B tv "AI 5 set-top box" swept all four major global design awards, having won Japan's Good Design Award last year, Germany's iF Design Award in March, and Germany's Red Dot Design Award in April.
