Final answer:
Nickelodeon wanted to create a movie about Fred Figglehorn to attract his web fans and capitalize on his online popularity, expecting that his web fanbase would be interested in a feature film about the character.
Step-by-step explanation:
Nickelodeon wanted to make a movie about Fred Figglehorn because they thought that people who liked Fred Figglehorn on the Web would enjoy a movie about him. This decision would likely have been driven by the character's existing popularity on digital platforms, and the potential for a film to further capitalize on that interest.
Rather than needing a way to find out about new webcasts or copying ideas, it was more about leveraging a current web sensation to create a successful movie for their target audience, which would result in attracting the web fans to the big screen and potentially pulling in new viewers.
