Unlicensed developers and fans have created unofficial Mario media, especially video games, relating to the Mario franchise. These products include video games, ROM hacks, and animations. Due to the popularity of the franchise, some of these unlicensed products have received critical attention. In September 2016, Nintendo issued over 500 DMCA takedown requests on diverse websites for various fan games based on Nintendo intellectual properties, resulting in the end of many infringing games' development.
