Hey Arnold

Hey Arnold! is an American animated television series created by Craig Bartlett for Nickelodeon. The show's premise focuses on a fourth grader named Arnold who lives with his grandparents in a large city. Episodes center on his experiences navigating big city life while dealing with the problems he and his friends encounter, including urban legends. Certain episodes focus on the lives of supporting characters, such as the tenants of the boarding house that Arnold's grandparents own.

Bartlett's idea for the show is based on a minor character named Arnold whom he created while working on Pee-wee's Playhouse. The executives enjoyed the character, and Bartlett completed the cast by drawing inspiration from people he grew up with in Portland, Oregon. He created the pilot episode in his living room in 1993, and official production began in 1994. The animators worked to transform Arnold from clay animation to cel animation.

The series aired on Nickelodeon from October 7, 1996 to June 8, 2004. Hey Arnold! received generally positive reviews, with many critics praising its character development and the quality of its animation. Over the course of its eight-year run, the series aired 100 episodes. A feature film based on the series, Hey Arnold!: The Movie, was released in 2002 to generally negative reviews. After the show's run, Bartlett created Dinosaur Train for PBS. Hey Arnold! is currently being released on DVD and rerun on the TeenNick block "The '90s Are All That".
