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.
Korean drama
Sageuk refers to any Korean television or film drama that is either based on historical figures, incorporates historical events, or uses a historical backdrop. While technically the word sageuk literally translates to "historical drama", the term is typically reserved for dramas taking place during Korean history.
