An animated series is a set of animated films with a common title, usually related to one another. These episodes typically share the same main heroes, some different secondary characters and a basic theme. Series can either have a finite number of episodes like, for example, miniseries, a definite end, or be open-ended, without a predetermined number of episodes. They can be released on television or the internet, in movie theaters or direct-to-video. Like other creative works, cartoon series can be of a wide variety of genres and have different target audiences: both males and females, both children and adults.
