Fan culture, also known as fandom, involves fans actively engaging with media through creative works like fan fiction, art, and videos rather than just passively consuming content. Henry Jenkins describes this as "participatory culture." Marvel is a good example as it has cultivated a large, dedicated fan base over decades across comics, films, TV shows, and more. While Marvel owns the characters, once a work is published fans feel entitled to reimagine and critique it. The rise of social media has empowered fans to directly communicate with media companies and shape franchises over time.
