How to write episodic synopses of TV shows

Shows in different languages are telecast on TV channels in different parts of the world. Many people in this world like to pass time by watching these TV shows. The episodes of these TV shows are integral parts of their daily lives. To make the process of watching these TV shows more enjoyable and to attract more viewers, certain agencies have started hiring candidates to write TV show episodic synopses. Writing TV show episodic synopses is a niche field currently and is controlled by a few major companies. Synopses are written for drama-based TV shows and for non-fictional ones. These synopses are used by DTHTV service providers for their set-top boxes and also by entertainment channels on their websites and social media platforms.
