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.

Serials rely on keeping the full nature of the story hidden and revealing elements episode by episode to keep viewers tuning in to learn more. Often these shows employ recapping segments at the beginning and cliffhangers at the end of each episode. Such shows also place a demand on viewers to tune into every episode to follow the plot. The invention of recording devices (such as VCRs, Digital video recorder (DVR) and TiVo) has made following these type of shows easier, which has resulted in increased success and popularity. Prior to the advent of DVRs, television networks shunned serials in prime time as they made broadcast programming reruns more difficult and television producers shunned them because they were tougher to go into broadcast syndication years down the road.
