Pay TV, also known as subscription television or premium television, refers to a type of television service that requires users to pay a subscription fee in order to access the content. This is in contrast to free-to-air or free-to-view television, which is funded by advertising and can be accessed without a subscription. Pay TV typically offers a wider range of programming, including exclusive content and premium channels, as well as additional features such as high-definition and on-demand viewing. Pay TV is delivered through a variety of technologies, including cable, satellite, and internet-based streaming services. It is a common option for households that want access to a wider range of content than is available through free-to-air television.
