Tokyo Movie Shinsha, also known as TMS, is one of the oldest and most prominent anime studios in Japan, and is cuurently owned by Sega under the name TMS Entertainment. Tokyo Movie Shinsha is the overseas studio that handled the animation for Spider-Man: The Animated Series.
The company was founded as Tokyo Movie in 1964 by Yataka Fujioka after his previous studio, Tokyo Ningyo Cinema failed. The first production of the studio was an animated adaptation of Osamu Tezuka's Big X. A year later, Daikichiro Kusube, Osamu Kobayashi and Tsutomu Shibayama formed a unit called A Production, where most of Tokyo Movie's animation productions would be made, as TM itself had little animators. Among the animators that were employed at A Production were Yasuo Otsuka, Osamu Dezaki, and Studio Ghibli co-founders IsaoTakahata and Hayao Miyazaki.
In 1972, Madhouse was established using finances of Fujioka, and co-produced it's earliest series with Tokyo Movie. In 1976, due to a decrease in animated TV series, Tokyo Movie was shut down, and A Production was sprung off into Shin-Ei Animation (shin meaning new in Japanese). In 1977, Fujioka reformed Toyko Movie into Tokyo Movie Shinsha (literally New Toyko Movie Company). It's first production was Lupin the Third Part II, which debuted with mass popularity. The movie adaptation of The Mystery of Mamo was the first feature-length movie produced in the studio's 13-year history. Another TMS subsidiary, Telecom Animation Film was founded in 1975, but didn't start production after Tokyo Movie was restructured. The real potential for Telecom wasn't realized until the studio produced The Castle of Cagliostro, which was Hayao Miyazaki's feature-length debut. Miyazaki remained emplyed at Telecom until he left to direct his second feature film, Nausicaa of the Valley of the Wind.
In 1980, TMS began their collaboration with Diffusion Information Communications, co-producing Ulysses 31. Throughout the 1980's and the 1990's and up to 2000, TMS animated for various animation companies including DiC, Walt Disney Television, Warner Bros. Animation, Marvel Films Animation, Shogakukan Music & Digital Entertainment among others and outsourced to smaller studios such as the aforementioned Telecom Animation Film, Ajia-do, Magic Bus, Studio Jungle Gym, Nakamura Production, Tokyo Kids, DR Movie, Orange among others. The studio has been credited as a key factor for the "American animation renaissance."
TMS struggled at the beginning of the 1990's, due to competition from Toei's Dragon Ball Z and Slam Dunk, as well as being too relient on foreign co-productions and the financial failure that was Little Nemo: Adventures in Slumberland. Sega-Kyokuichi pruchased TMS in 1992 after Fujioka retired. During this period, productions by TMS was credited as TMS-Kyokuichi. Since 2000, TMS has focused on it's own productions, rather than outsiurcing animation for other studios, however they still do outsourcing for studios like Sunrise, Studio Ghibli and Bones to this very day.
