Nelvana Enterprises, Inc. (/ˈnɛlvɑːnə/) (previously known as Nelvana Limited, sometimes known as Nelvana Animation, stylized as nelvana) is a Canadian animation studio and children's entertainment company owned by Corus Entertainment. Founded in 1971, it was named by founders Michael Hirsh, Patrick Loubert and Clive A. Smith after a Canadian comic book superheroine created by Adrian Dingle in the 1940s. The company's production logo is a polar bear looking at the North Star, although a design featuring multiple stars was in use from 1985 to 2004. Most of their films, shows and specials are based on licensed properties, mainly children's literature but also comic books and novels, however original programming is also part of its roster. (Literature adaptations are a common pattern in the company's content library, see List of Nelvana programs down below.) It ventured into the world of live action from its establishment in 1971 and continues to do so. Nelvana also internationally distributes two Nickelodeon shows: Taina, and the first five seasons of The Fairly OddParents.[4] As of 2001, its library comprises more than 1,650 cumulative half-hours of original programming.[1] The company maintains international offices in France, Ireland and Japan, and smaller offices in the United States. Although the company specializes in making children's media, they have also made adult-animated series like Clone High, Bob & Margaret and Committed.
