Basic Cable serves as the foundational content offering, around which other services, such as Video on Demand (VOD), Pay-Per-View (PPV), and Premium Channels, are offered as additional, more specialized options. These latter services often require separate subscriptions or additional fees beyond the basic package. Cable companies receive subscriber fees which allow channels to thrive financially, offering viewers a stable selection of programming.Cable companies also offer Video on Demand (VOD), which allows viewers to watch content at their convenience, though often with commercials.
