Canadian science fiction television was produced by the CBC as early as the 1950s. In the 1970s, CTV produced The Starlost. In the 1980s, Canadian animation studios including Nelvana, began producing a growing proportion of the world market in animation. In the 1990s, Canada became an important player in live action speculative fiction on television, with dozens of series like Forever Knight, Robocop, and most notably The X-Files and Stargate SG-1. Many series have been produced for youth and children's markets, including Deepwater Black and MythQuest.
