Original video animation
As original video animation , short OVA ( Jap. オリジナル·ビデオ·アニメーション orijinaru Bideo animēshon ) are anime called, as opposed to feature films and television series are from the outset produced exclusively for publication on the video market.
OVAs are in many cases series with a small number of episodes or individual films and can be the continuation of a television production, but they can also be independent projects. One of the few exceptions is Ginga Eiyū Densetsu , a 110-episode series that was first released on video and is therefore considered an OVA. This format had its heyday in the 1990s, but became less common with the advent of television series with 12 to 13 episodes.
The abbreviation OAV (from Original Animation Video ) was also used in the past . However, this was not used because AV ( Adult Video ) refers to pornographic films. DVDs that are published as supplements to manga volumes are called OAD ( Original Animation DVD ).
