Serial (radio and television)
In television and radio programming, a serial has a continuing plot that unfolds in a sequential episode-by-episode fashion. Serials typically follow main story arcs that span entire television seasons or even the full run of the series, which distinguishes them from traditional episodic television that relies on more stand-alone episodes. Worldwide, the soap opera is the most prominent form of serial dramatic programming.
Television show
A television show might also be called a television program (), especially if it lacks a narrative structure. A television series is usually released in episodes that follow a narrative, and are usually divided into "seasons" (US and Canada) or "series" (UK) – yearly or semiannual sets of new episodes. A show with a limited number of episodes may be called a miniseries, serial, or limited series. A one-time show may be called a "special". 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.
