Charter

Charter Communications runs the Spectrum brand, serving residential and business customers across 41 states with roughly 32 million customer relationships, which makes it the second-largest US cable and broadband operator after Comcast. Broadband subscriptions, video bundles and advertising bring in its revenue, and the advertising increasingly rests on first-party household data collected across its own network.

Founded in 1993 and headquartered in Stamford, Connecticut, Charter grew through acquisitions. The largest, the roughly $78bn merger with Time Warner Cable and Bright House Networks in 2016, about trebled its footprint and joined three separate cable systems under the single Spectrum name.

That address-level data puts Charter in the frame whenever a streamer or broadcaster weighs building or buying connected-television audiences. When Fox agreed on 15 June 2026 to pay $22bn for Roku, gaining device-level viewing data from more than 100 million streaming households, it was buying its way into a targeting model that cable operators such as Charter already run.
