Transmedia refers to the practice of telling a single story or narrative across multiple platforms and media forms, such as books, films, television shows, video games, and social media. This approach allows for a more immersive and interactive experience for the audience, as each platform adds new layers and dimensions to the story. Transmedia storytelling often involves collaboration between different creators and encourages audience participation and engagement. It allows for a more expansive and dynamic world-building, creating a rich and diverse universe for the audience to explore and engage with.
