Sensation Animation was a subsidiary group of Buena Vista Television, dedicated to ADR production and post-production services for anime.
Following Disney's purchase of Saban Entertainment in 2001, the company was renamed to BVS Entertainment and its french division Saban International Paris was split up and later renamed SIP Animation after Disney purchased a minorty stake in the studio.
Saban's two prime shows, Power Rangers and Digimon, continued to be produced how they were. Power Rangers' production was moved to New Zealand after the production of Wild Force was completed and produced under BVS Entertainment, but the production of Digimon remained how it was under the same group of people who had worked on the show previously - except now, that group was named "Sensation Animation".
Following the completion of Digimon's fourth season in 2003, Digimon went on hiatus (The next series, Digimon Data Squad didn't premiere in the US until 2008) and Disney lost the rights to dub the series, and therefore Sensation Animation dissolved, by all appearances having only ever existed in order to complete this task. The subsequent release of the four previously-undubbed Digimon movies in 2005 was handled by STUDIOPOLIS, Inc. The majority of the previous cast members returned sans some actors, like Joshua Seth.
