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.
Radionovela
A radionovela (also known as serial radiofónico or simply serial) is a type of radio drama first broadcast in Latin America in the early 20th century. Radionovelas are typically melodramas or soap operas which are issued in chapters, in contrast to other radio dramas which may encompass different genres and are often broadcast as individual works, such as "The War of the Worlds".
