Uncle Grandpa is an American animated television series created by Peter Browngardt that premiered on Cartoon Network on September 2, 2013. The series tells about everybody in the world's uncle and grandpa named Uncle Grandpa. When he comes to visit, it is sure be a time no one will ever forget. Based on Browngardt's short film of the same name from The Cartoonstitute, Uncle Grandpa is also a spin-off of Secret Mountain Fort Awesome (even though originally, Secret Mountain Fort Awesome was created instead of Uncle Grandpa, so technically it is a spin-off of the very same show that is claimed to be a spin-off of it). The show is rated TV-PG. It is produced by Cartoon Network Studios. On April 2, 2016, It started its own block called Good Mornings with Uncle Grandpa, which ended before the Summer of 2016 ended. The show will conclude on June 30, 2017.
The Uncle Grandpa pilot was created by former Chowder storyboard artist Peter Browngardt in 2008, but aired online in 2010 on Cartoon Network Video as part of The Cartoonstitute. Just like the Regular Show pilot, the Uncle Grandpa pilot was successful, but it didn't green lit into it's own show yet. In 2011, Secret Mountain Fort Awesome aired on Cartoon Network, and was bad-mouthed by people, because it looked disgusting. Browngardt decided it would be the right idea for Uncle Grandpa to have its own show as well. In 2012, Cartoon Network announced two new shows, "Uncle Grandpa" by Peter Browngardt, as well as Steven Universe by Rebecca Sugar. Uncle Grandpa aired on September 2nd, 2013 on Cartoon Network.
