Fan labor is when fans of movies, TV shows, books, or other forms of entertainment create their own content based on the original material. This can include artwork, fan fiction, videos, and more. For instance, if you really love Harry Potter, you might write your own story set in the wizarding world, or draw a picture of your favorite characters. These fans aren't getting paid for their work, they are doing it for fun and as a way to express their love for something they enjoy. It's kind of like when you draw a picture of your favorite cartoon character or make up a story about them, but on a bigger scale. People who create fan labor are usually very passionate about what they're doing and spend a lot of time perfecting their work. It's a great way to show creativity and connect with other fans who share the same interests.
