Television program

distinguish|broadcast programming}}

A television program is a segment of content intended for broadcast on vision, other than a commercial, trailer, or any other segment of content not serving as attraction for viewership. It may be a single production, or more commonly, a series of related productions (also called a television series).

A television series that is intended to comprise a limited number of episodes may be called a miniseries or serial. Series without a fixed length are usually divided into seasons or series, yearly or semiannual sets of new episodes. While there is no defined length, US industry practice tends to favor longer seasons than those of some other countries.

A one-time broadcast may be called a "special," or particularly in the UK a "special episode." A television film ("made-for-TV movie" or "television movie"), is a film that is initially broadcast on television rather than released in theaters or direct-to-video.

A program can be either recorded, as on video tape, other various electronic media forms, played with an on-demand player or viewed on live television.

Reality television

Reality television is a genre of television programming that documents ostensibly unscripted real-life situations, and often features an otherwise unknown cast of individuals who are typically not professional actors, although in some shows celebrities may participate. It differs from documentary television in that the focus tends to be on drama, personal conflict, and entertainment rather than educating viewers. Reality TV programs also often bring participants into situations and environments that they would otherwise never be a part of. The genre has various standard tropes, including "confessionals" used by cast members to express their thoughts, which often double as the shows' narration and competitive elements. Reality TV shows often have a host who asks questions to the participants or comments on the participants. In competition-based reality shows, a notable subset, there are other common elements such as one participant being eliminated per episode, a panel of judges, and the concept of "immunity from elimination."
