Diary of a Wimpy Kid was published by Amulet Books (an imprint of Abrams) in 2007, though it originated as an online serial on FunBrain.com beginning in 2004. Greg Heffley, a scrawny, self-absorbed middle schooler, records his experiences in what he insists is a “journal” (not a diary) — navigating the social hierarchy, dealing with his older brother Rodrick and younger brother Manny, and scheming to achieve popularity through shortcuts rather than genuine effort.
The book’s format — handwritten-style text interspersed with simple stick-figure illustrations on every page — was revolutionary in children’s publishing. It made reluctant readers feel they were consuming something closer to a comic than a traditional novel, while the text itself delivered sophisticated observational humor about childhood social dynamics. Greg is not a hero: he is selfish, cowardly, and frequently cruel to his best friend Rowley Jefferson. This antiheroic characterization is precisely what makes the series ring true to its target audience.
The series has sold over 275 million copies in 82 editions and 65 languages, spawning multiple films, a theme park attraction, and a publishing empire that includes spin-off series.

Frequently Asked Questions
How did Diary of a Wimpy Kid start? Kinney worked on the concept for eight years before publishing. It launched as an online comic on FunBrain.com in 2004, accumulating 20 million page views before Abrams/Amulet acquired the book rights. The online version contained material that was reworked and expanded for the print editions.
Is Greg Heffley a good person? Deliberately not. Kinney has said Greg is meant to be “the kid you don’t want your child to become.” His selfishness, cowardice, and mistreatment of Rowley are played for dark comedy, and the series never rewards Greg’s bad behaviour — a moral sophistication that distinguishes it from simpler children’s fiction.
