Cartoon Network announced Thursday (Sept. 29) that one of its most popular shows, “Adventure Time,” will end in 2018 after nine seasons and “142 half-hours” worth of content.

“Adventure Time” was created by Pendleton Ward and premiered in 2010, instantly becoming one of the network’s most-watched programs. The show follows a human boy named Finn and his shape-shifting canine friend, Jake, as they embark on trippy adventures in the post-apocalyptic, yet magical Land of Ooo.

“‘Adventure Time’ was a passion project for the people on the crew who poured their heart into the art and stories,” Ward said in a statement. “We tried to put into every episode something genuine and telling from our lives, and make a show that was personal to us, and that had jokes too! I’m really happy that it connected with an audience for so long. It’s a special thing, I think.”

The show has drawn praise from critics and fans for its unique art style, creative storytelling, odd characters and surprising depth, resulting in six Emmy wins and its status as a cult classic among children and young adults.

“‘Adventure Time’ changed the definition of what a kids’ TV series could be, and it’s had a resounding impact upon popular culture around the world,” Rob Sorcher, chief content officer for Cartoon Network, said. “Cartoon Network Studios is proud to have brought together this group of brilliant artists and animators who helped make ‘Adventure Time’ one of the most critically acclaimed TV series of a generation.”

The announcement comes on the heels of similar news regarding another one of Cartoon Network’s well-received series, “Regular Show,” which will wrap up after its eighth season concludes in January 2017.

A premiere date hasn’t been set for the eighth season of “Adventure Time,” but it is expected to return in late 2016. The ninth and final season is currently in production.
