Animation World Network: A Capsule History of AnimeThe history of anime began at the start of the 20th century, when Japanese filmmakers experimented with the animation techniques that were being explored in the West. During the 1970s, anime developed further, separating itself from its Western roots, and developing distinct genres such as mecha and its Super Robot sub-genre. Typical shows from this period include Lupin III and Mazinger Z. During this period several filmmakers became famous, especially Hayao Miyazaki and Mamoru Oshii.
As a result, Tezuka organized Japan's first TV animation studio, Mushi Productions. Not counting an experimental art film, Stories on a Street Corner (1962), its first release was a weekly series based upon Astro Boy, which debuted on New Year's Day 1963. It was such an instant success that, by the end of 1963, there were three more television animation studios in production and Toei Animation had opened a TV division. By the end of the 1960s, the popularity of TV science-fiction action-adventure anime was so overwhelming that Toei began to alternate it with fairy-tale fare for its theatrical features.
