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.
SK Broadband earned the "2026 Best HRD" certification on September 18, 2026, acknowledging its performance in talent-centered management and overall human resource development from government-sponsored national certification bodies. This development occurred as concerns were raised on September 11 regarding South Korea's international submarine cables, found to be less than one-third of Japan's, potentially impacting the country's intensifying competition for AI data centers and GPUs. Previously, on September 10, SK Broadband's union demanded a new growth strategy and funding commitments following the company's plan to spin off its data center and proprietary submarine cable-based international leased-line businesses into a new entity, SK Horizon. The spin-off is scheduled for February 1, 2027, with SK Broadband remaining the surviving company.
