The pilot episode was created in 2008 and then was aired on Cartoon Network Video in 2010 as part of the show project The Cartoonstitute, while the series premiered on September 2, 2013.

The already-ordered third season likewise was divided into the newly ordered "season four" and season five".
The series concluded on June 30, 2017, after the series finale "Uncle Grandpa: The High School Years" with 5 seasons and a total of 153 episodes.
During the course of the series, 153 episodes of the series aired over five seasons.
