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.
Series finale
Television series finales frequently feature fundamental deviations from the central plot line, such as the resolution of a central mystery or problem, (e.g. "Dallas", "Two and a Half Men", "Full House") the separation or return of a major character (e.g. "Cheers", "That '70s Show", "The Office") or an event signifying the end of an era, such as a change to primary setting for the series (e.g. "The Mary Tyler Moore Show", "Boy Meets World", "Martin".)
