Since its creation in 1984, the company has evolved from a first generation analog cellular system, to second generation CDMA, then to the world's first third-generation synchronized IMT-2000 cellular system. SK Telecom also became the world's first carrier to commercialize HSDPA in May 2006. SK expanded into the landline market by acquiring second-rated fixed-line operator Hanaro Telecom in February 2008.^[4]

In November 2015, SK Telecom announced signing a deal to acquire CJ HelloVision, the country's largest cable and Internet operator, with the view to merge it with its own cable unit, SK Broadband.^[6] The acquisition, which will make SK Broadband the second largest cable broadcaster following KT,^[7] is opposed by competitors, who charge that the merger will help SK unfairly dominate the market.^[8][9]
