Jimmy Neutron began as the 2001 animated film Jimmy Neutron: Boy Genius, which led to the Nickelodeon television series The Adventures of Jimmy Neutron, Boy Genius, running from 2002 to 2006. The show followed a young inventor in Retroville whose experiments often created more chaos than solutions, and it became a defining cartoon for many 2000s viewers. Short clips from the series continue to circulate online as nostalgic soundboard sounds, reused in edits, reaction videos, and memes that play on clever ideas and retro cartoon humour.
