Television spin-offs are new shows that are created based on characters or storylines from an existing series. They often focus on a specific character or group of characters, allowing for deeper exploration of their lives and adventures. Spin-offs can attract fans of the original show while also appealing to new audiences. These shows can vary in tone and style, sometimes maintaining the same genre as the original series. Popular examples of spin-offs include Frasier, which followed the character from Cheers, and Better Call Saul, a prequel to Breaking Bad. Spin-offs can contribute to the overall success and longevity of a franchise.
