Originally launched as 9anime in 2016, the platform rebranded to AniWave in 2023. It gained popularity for offering a vast library of anime content with features like high-definition streaming, options for English subtitles or dubbing, and the ability to download episodes without registration. The site emphasized user experience, providing functionalities such as watchlists, folder creation, and a "Watch2Gether" feature for synchronized viewing with friends.

However, in August 2024, AniWave, along with several related streaming sites, was shut down following actions by copyright enforcement organizations, including the Alliance for Creativity and Entertainment. The shutdown was part of a broader effort to combat unauthorized distribution of copyrighted content.

AniWave's evolution from a local convention to a major online streaming platform underscores the dynamic nature of anime fandom and the ongoing challenges related to content distribution and intellectual property rights.
