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.

The 19:00 to 20:00 evening time slot is usually for daily dramas that run from Monday through Friday. Dramas in these slots are in the telenovela format, rarely running over 200 episodes. Unlike American soap operas, these daily dramas are not also scheduled during the day-time. Instead, the day-time schedule often includes reruns of the flagship dramas. The night-time dailies can achieve very high ratings. For example, the evening series "Temptation of Wife" peaked at 40.6%, according to TNS Korea.
