Extensive Network Infrastructure: Charter owns and operates a vast hybrid fiber-coaxial (HFC) and fiber optic network, covering millions of homes and businesses across its service areas, which represents a massive sunk cost and high barrier to entry for competitors.

Large Scale and Market Share: As one of the largest broadband and cable providers in the U.S., Charter benefits from significant economies of scale in network operations, content acquisition, and marketing, leading to cost efficiencies and strong brand recognition.

Bundled Service Offerings: Charter's ability to offer attractive bundles of high-speed internet, video, and voice services provides convenience and potential cost savings to customers, enhancing customer loyalty and reducing churn rates.
