evidence: That's All, Folks! Cartoon Network Website Is No More After 26 years, Cartoon Network's web portal has been shut down to push viewers toward streaming services. The website for Cartoon Network, which had existed online since 1998, has been scrubbed from the internet. What once was a video-heavy portal for shows, including The Powerpuff Girls, Adventure Time, Teen Titans Go! and Steven Universe, now redirects users to the streaming service Max, also owned by Warner Bros. Discovery.
