SK Broadband, Inc. (formerly Hanaro Telecom) is a Seoul-based telecommunications company and a wholly owned subsidiary of SK Telecom. It is one of the largest 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.
In October 2014, SK Broadband unveiled the world's first 10 Gbit/s Internet service at the ITU Plenipotentiary Conference. The new Internet service is 100 times faster than existing LAN services in South Korea, which deliver download speeds of 100 Mbit/s.[3][4]
