Abstract: A storytelling system that simplifies the filmmaking process to enable end-users, including, but not limited to, audiences of movies, TV shows, and commercials, and product-narrative owners, including, but not limited to studios, TV networks, filmmakers, and brands, to co-produce audio-visual stories as extensions of existing product-narratives. The system includes, but is not limited to, story prompts that direct end-users' filmmaking activities, protocol to frame creation of audio-visual stories within the product-narrative, a function for end-users to choose relationship status between one another within the product narrative, and a method to catalogue activity within the system, which can be delivered in varying formats.
