Short answers, pulled from the story.
Yoshito Usui introduced Crayon Shin-chan to readers in 1990 through Weekly Manga Action, a publication by Futabasha. The character first appeared as a spin-off within another series called Darakuya Store Monogatari.
Usui died after falling from Mount Arafune while hiking alone. His death left the series without its creator at a time when it was already a massive commercial success.
The final chapter of the original series shipped on the 5th of February 2010. A new team led by Usui's assistants began work on a continuation titled New Crayon Shin-chan that summer.
The Indian Ministry of Information and Broadcasting banned the series in October 2008 due to heavy nudity concerns. Parents complained about the main character's behavior and attitudes exhibited towards elders being negative influences on children.
An anime adaptation began airing on TV Asahi on the 13th of April 1992 under producer Shin-Ei Animation. The series was originally scheduled to end in 1994 but became a huge hit on TV Asahi.
