Bocquelet based several of the series' characters on rejected characters from his previous commercial work and making its premise a mixture of "family shows and school shows", which Cartoon Network was heavily interested in. He pitched The Amazing World of Gumball to the network and Turner Broadcasting executive Daniel Lennard subsequently greenlit production of the series.
