Created by Ben Bocquelet, the series is the first commission from Turner Broadcasting's Cartoon Network Development Studio Europe. Combining a mixture of several animation techniques with live-action backgrounds, the series follows the misadventures of a hapless twelve year old cat named Gumball, who lives in the quaint little town of Elmore - where nearly everything has the power to come to life! Joining him is his best friend Darwin, the one-time pet fish who grew legs and joined the family. The two of them go to Elmore Junior High where all sorts of strange characters roam the halls.
The series received a twenty-episode second season before the eighteen-episode first season even premiered, another twenty-episode third season shortly after the second season premiere, and two more twenty-episode seasons right before the third season premiere, and the sixth season was extend by two episodes, bringing its total to 50 hours (a little over two days) worth of episodes. It got a "sneak peek" (i.e., the first of two episodes) in the UK on May 2nd, 2011, and in the US on May 3. On June 22nd, 2016, it was announced that the show was renewed for a sixth season. In September 2016, series creator Ben Bocquelet confirmed that the sixth season will be his last season, but that this is not necessarily the end of the show.
In March 2018, Ben Bocquelet asked users in his Twitter if they would like a movie based on the show. Due to mostly positive responses for The Movie, he later announced he would try to make it happen. As of now, a script is currently being written, but it wasn't greenlit yet.
