A comic book series (based on the TV show) was published by DC Comics under the Johnny DC imprint, which lasted 6 issues, from 2005 to 2006. The show was designed primarily for young children. However, as a result of being aired (and cancelled) in the mid-2000s, it has made an imprint on the older child demographic as of 2012.
The show was produced in a manner reminiscent of the Hanna-Barbera shows of the 1960s to the 1980s, from the sound effects down to the animation style (veteran Hanna-Barbera designer Iwao Takamoto served as a creative consultant). The series is rated TV-Y.
The show was close captioned by the National Captioning Institute like many of Warner Bros Animation's shows at the time.
