This article is about television services that are available for an additional monthly fee to cable and satellite subscribers, and in some cases, through terrestrial television. For the forms of subscription television services in which “pay television” is also sometimes used as a generalized term, see Multichannel video programming distributor, cable television or satellite television. Pay television, premium television, or premium channels refer to subscription-based television services, usually provided by both analog and digital cable and satellite television, but also increasingly via digital terrestrial and internet television. Subscription television began in the multi-channel transition and transitioned into the post-network era. Some parts of the world, notably in France and the United States, have also offered encrypted analog terrestrial signals available for subscription.
