What Comporium does

Comporium, Inc. is a privately held, family-owned (five generations of the Barnes family since 1912) diversified telecommunications company headquartered in Rock Hill, South Carolina, founded in 1894 as Rock Hill Telephone Company and rebranded to Comporium Group in 2001. The company delivers residential and business communications services — high-speed fiber internet (Zipstream, up to 1 Gbps for residential and up to 5 Gbps on fiber for select footprints), digital TV (Stream TV and HD channel packages of 173-219 channels), 24/7 monitored smart-home security (powered by Alarm.com), local and long-distance home phone, and Premium WiFi managed via Plume — across more than 4,500 square miles of South Carolina and North Carolina, serving over 150,000 customers.

Underlying the offering is a continually expanding fiber-optic network built through capital-intensive private investment paired with state broadband grants (including a $51.9M award from the SC Broadband Office in December 2023) and electric cooperative partnerships (notably a $16M, 600-mile build with York Electric Cooperative). The technology stack blends proprietary fiber infrastructure with third-party platforms — Plume for adaptive mesh and security filtering, Alarm.com for interactive monitoring, Trend Micro for subscriber antivirus — across multiple subsidiaries (Catawba Services, Video Vision, SunBelt.Net, Telewatch Security Systems, Media Services, and the DashHound agency service).

Comporium monetizes primarily through recurring monthly subscriptions, with internet entry tiers at $39.94 (400 Mbps) and top residential tiers at $65 (1 Gbps), TV packages priced $127.90-$140.85, security monitoring from $39.99, and Premium WiFi at $9.99. Distribution combines direct-to-consumer channels (shop.comporium.com, multiple retail showrooms across SC/NC, phone sales at 888-403-2667) with a dedicated business development team for builders, developers, and property managers, and with channel partners such as York Electric Cooperative for rural areas. The company employs nearly 900-1,000 staff and is led by David Barnes, the fifth-generation family CEO who succeeded his father Bryant Barnes on July 1, 2025.
