Cox Communications

Third-largest U.S. cable operator and a major player in local, regional, and national TV advertising through Cox Media and the Ampersand JV

Cox Communications is the third-largest cable operator in the United States, serving approximately 6.5 million residential and business customers across 18 states. As a privately held subsidiary of Cox Enterprises, it provides video, broadband internet, voice, and home-automation services. In the AdTech ecosystem, Cox operates through its advertising subsidiary Cox Media, which leverages its subscriber data and cable footprint to offer local, regional, and national advertising solutions across linear TV, digital, and addressable channels. Cox is a co-owner of Ampersand (formerly NCC Media), a multichannel video advertising sales joint venture shared with Comcast and Charter Communications. This partnership gives Cox Media access to a combined national footprint of cable subscribers, enabling advertisers to execute large-scale, data-driven TV campaigns. Cox Media also offers addressable advertising capabilities, allowing advertisers to target specific households based on first-party subscriber data, viewing behavior, and third-party data integrations. In the broader AdTech landscape, Cox Media competes with other MVPDs and streaming platforms for local and national TV ad budgets, while also expanding into digital and OTT advertising. Its scale, first-party data assets, and participation in Ampersand make it a significant player in the convergent TV advertising space, particularly for advertisers seeking to reach audiences across traditional cable and emerging digital platforms.
