Games Animation Inc was a production company that co-produced Hey Arnold! with Snee-Oosh, Inc. It was later renamed Nickelodeon Animation Studios.
In 1991, Nickelodeon founded Games Animation as its own animation division under the guidance of Vanessa Coffey and Mary Harrington, who reported to Nickelodeon programming chief Herb Scannell. The initial duty was to continue producing The Ren & Stimpy Show as Nickelodeon dropped Spümcø and its creator John Kricfalusi from their duties on the show due to production delays.
At the time, Games was located in an office building in Studio City, California. Apart from The Ren and Stimpy Show, Nickelodeon's other Nicktoons were done out-of-house at Jumbo Pictures (creators of Doug) in New York City and Klasky-Csupo (creators of Rugrats).
Games Animation never had its official logo. Instead, every show the studio worked on had its own customized Games Animation logo.
A year later, Nickelodeon greenlit its first fully original in-house series, Rocko's Modern Life, produced by Games Animation with partnership of Joe Murray Studios. Games worked on the show for three years and employed over 70 people during the course of its run. The show was cancelled in 1996 by Nickelodeon due to its creator Joe Murray wanting to spend more time with his family.
Following the cancellation, Games Animation produced the pilot of Hey Arnold!, and its first 26 episodes. All the episodes produced by Games end with Arnold holding some blue chalk and the words "Games Animation Inc" can be read behind him.
