A "Shared Universe" refers to a fictional setting where multiple stories, characters, and events coexist and interact across various media. This concept allows different creators to build upon a common framework, enriching the narrative and expanding the audience's experience. Examples include comic book franchises like Marvel and DC, where superheroes and villains appear in interconnected storylines. In a shared universe, characters can cross over into each other's stories, creating unique interactions and plot developments. This approach encourages collaboration among writers and filmmakers, leading to larger, more complex narratives. Notable examples also include Star Wars and The Wizarding World, which have expanded through films, books, and other forms of entertainment.
