In 2001, "Shrek" was released and went on to win the first Academy Award for Best Animated Feature Film. Due to the success of CGI animated films, DWA decided the same year to exit hand-drawn animation business after the next two of total four hand-drawn films. Beginning with "Shrek 2" (2004), all released films, other than some co-produced with Aardman, were expected to be produced with CGI. The releases of "Shrek 2" and "Shark Tale" also made DWA the first animation studio to produce two CGI animated features in a single year.
