Определение и Значение "spin-off"

What is a "spin-off"?

A spin-off is a work of fiction, such as a film, TV show, or book, that originates from an existing series and focuses on characters, settings, or themes introduced in the original work. Unlike a sequel or prequel, which continues or precedes the main storyline, a spin-off explores new stories related to a specific aspect of the original. It often features characters or elements from the original work in a different context or setting. Spin-offs aim to expand on the original story's universe and appeal to fans by offering additional content connected to the established series.
