While the majority of the canon are original, six are sequels: The Three Caballeros, The Rescuers Down Under, Fantasia 2000, Winnie the Pooh, Ralph Breaks the Internet: Wreck-It Ralph 2, and Frozen 2.
For advertising purposes, the Walt Disney Company began to affix numbers to each of the films in the late 1980s. Through this method, they could proclaim the film to be "Disney's X full-length animated film". When the numbering system was introduced, the group of films included became collectively known as the "Disney Animation Canon." Many film historians and animation fans refer to them as Disney "classics" or Disney "features". The numbering system remains today, as recent press releases for such products as the 20th anniversary edition of Oliver & Company, as well as the opening and closing logos and marketing materials for Tangled, still refer to the film's number. Some foreign numbering systems of Disney Animated Classics exclude Dinosaur and include The Wild. However, The Wild was not produced by Walt Disney Animation Studios nor Disney in that matter, let alone owning the films' distribution rights. In some countries, Winnie the Pooh does not count as a classic, leaving Wreck-It Ralph in 51st place.
