Many studios have been "spun off" from Sunwoo; the first to do so was Anivision, which was established in March 1991. Anivision worked on The Simpsons, with AKOM and Rough Draft Studios, and Rugrats, replacing Wang Film Productions for its 2nd season in 1992. Grimsaem Animation Co. Ltd., Seoul, Korea, which mainly does feature-length work for Nickelodeon, was established in March 1997. In April 1998, Sunwoo Digital International was established, whose most notable work was for the Fox TV series Family Guy. In April 2000, all of these spin-off studios were merged under the banner Sunwoo Entertainment, and it has remained that way ever since.
