CCS (legal name CCS Chungbuk Broadcasting), established in 1997, is a comprehensive cable system operator (SO) covering two cities (Chungju, Jecheon) and five counties (Eumseong, Goesan, Danyang, Jincheon, Jeungpyeong) in Chungcheongbuk-do province.
It operates under a broadcasting license approved through January 2030 by the Korea Communications Commission, providing cable TV service over its own transmission network.
As an ancillary service, it has offered broadband internet since 1999 in partnership with SK Broadband, delivering up to 100Mbps over legacy cable lines and up to 1Gbps via optical LAN and FTTH dedicated lines, along with an internet phone service.
Its advertising segment generates revenue through home-shopping channel leasing, its own local channel advertisements, and PP spot ads tailored to the regional market. The company has also pursued diversification into local event management, themed travel, broadcast content distribution, and rental businesses.
Its competitive landscape is marked by intensifying competition from IPTV, satellite broadcasting, OTT services, and mobile video platforms, a structural pressure faced broadly across Korea's cable SO industry.
Between 2023 and 2025, amid its shareholder control dispute, researchers associated with superconductor claims were appointed as in-house directors and a superconductor-device manufacturing purpose was added to the corporate charter, though no concrete commercialization has been confirmed.
