Broadcast programming is the practice of scheduling broadcast media shows, typically radio and television, in a daily, weekly, monthly, quarterly, or season-long schedule.
Modern broadcasters use broadcast automation to regularly change the scheduling of their shows to build an audience for a new show, retain that audience, or compete with other broadcasters' shows. Most broadcast television shows are presented weekly in prime time or daily in other dayparts, though there are many exceptions.
Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fibre-optic cables. This contrasts with broadcast television, in which the television signal is transmitted over-the-air by radio waves and received by a television antenna, or satellite television, in which the television signal is transmitted over-the-air by radio waves from a communications satellite and received by a satellite dish on the roof. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation.
A cable channel (sometimes known as a cable network) is a television network available via cable television. Many of the same channels are distributed through satellite television. Alternative terms include non-broadcast channel or programming service, the latter being mainly used in legal contexts. The abbreviation CATV is used in the US for cable television and originally stood for community antenna television, from cable television's origins in 1948; in areas where over-the-air TV reception was limited by distance from transmitters or mountainous terrain, large community antennas were constructed, and cable was run from them to individual homes.
A television show, TV program (British English: programme), or simply a TV show, is the general reference to any content produced for viewing on a television set that is transmitted via over-the-air, satellite, and cable, or distributed digitally on streaming platforms. This generally excludes breaking news or advertisements that are aired between shows or between segments of a show. A regularly recurring show is called a television series, and an individual segment of such a series is called an episode. Content is produced either in-house on a television stage with multiple cameras or produced by contract with film production companies. Episodes are usually broadcast in annual sets, which are called seasons in North America and series in other regions. A one-off television show may be called a television special, while a show with a limited number of episodes is a miniseries. A television film, or telefilm, is a feature film produced for broadcast by a terrestrial or cable network.
Television shows by terrestrial and cable networks are most often scheduled for broadcast ahead of time and appear on electronic guides or other TV listings. The rise of streaming television, however, has made television schedules less relevant than in earlier decades. Some programming may be aired live—that is, events are broadcast at the time they happen rather than at a later time or date—but the vast majority of programming is produced ahead of time. Originally, viewers had no practical way to record a show for later viewing; this changed with the advent of home video, first in the form of videotape recorded on VCRs and later in the form of digital video recorders. Cable television providers began offering certain programming "pay-per-view" or on-demand, with viewers paying a one-time fee to watch a program at a time of their own choosing. Streaming television allows viewers to watch programming at any time with a subscription to the OTT platform service.
Electronic programming guides (EPGs) and interactive programming guides (IPGs) are menu-based systems that provide users of television, radio, and other media applications with continuously updated menus that display scheduling information for current and upcoming broadcast programming (most commonly, TV listings). Some guides also feature backward scrolling to promote their catch up content. They are commonly known as guides or TV guides.
Non-interactive electronic programming guides (sometimes known as "navigation software") are typically available for television and radio, and consist of a digitally displayed, non-interactive menu of programming scheduling information shown by a cable or satellite television provider to its viewers on a dedicated channel. EPGs are transmitted by specialized video character generation (CG) equipment housed within each such provider's central headend facility. By tuning into an EPG channel, a menu is displayed that lists current and upcoming television shows on all available channels.
Video on demand (VOD) is a media distribution system that allows users to access videos, television shows and films digitally on request. These multimedia are accessed without a traditional video playback device and a typical static broadcasting schedule, which was popular under traditional broadcast programming, instead involving newer modes of content consumption that have risen as Internet and IPTV technologies have become prominent, and culminated in the arrival of VOD and over-the-top (OTT) media services on televisions and personal computers.
Television VOD systems can stream content, either through a traditional set-top box or through remote devices such as computers, tablets, and smartphones. VOD users may also permanently play content to a device such as a computer, digital video recorder (DVR) or, a portable media player for continued viewing. The majority of cable and telecommunications company–based television providers offer MOD streaming, whereby a user selects a video programme that begins to play immediately, or downloading to a rented or purchased from the provider, to a device for deferred viewing.
A television broadcaster or television network is a telecommunications network for the distribution of television content, where a central operation provides programming to many television stations, pay television providers or, in the United States, multichannel video programming distributors. Until the mid-1980s, broadcast programming on television in most countries of the world was dominated by a small number of terrestrial networks. Many early television networks such as the BBC, CBC, PBS, PTV, NBC or ABC in the US and in Australia evolved from earlier radio networks.
