Pay-TV
Pay television channels are premium services funded by subscription fees paid by the customer, rather than advertising. They typically deal in premium content, such as feature films (typically within a release window between their theatrical release and their release on home video), and original series and specials. Some entertainment-oriented premium services have broadcast occasional sporting events; in the U.S., premium networks such as HBO and Showtime are well known for their broadcasts of boxing (HBO ended its boxing telecasts in 2018). Due to their cost and more limited availability, premium networks are usually more lenient in regards to content, and may air content largely uncensored (by contrast, in the U.S., many basic cable networks self-censor their programming for violent, profane, and sexual content because of viewer and advertiser expectations, and broadcast channels are restricted by law on their airing of "indecent" material). Some premium networks may broadcast (particularly in late-night hours), or are dedicated entirely, to pornography. A modern premium service typically consists of multiple channels, including a main flagship channel, and several "multiplex" channels focusing on certain genres or demographics.
