The origins of these videos can perhaps be traced back to YouTube user, TonyWDA . His work primarily consisted of simple editing, such as changing the music in finales or adding laugh tracks. However, most would know him for his animated crossovers, which consisted of splicing various cartoons to react to a certain scene. The efforts of this dude caught the attention of a lesser Youtuber named bredaniel (now under the alias of Disneydaniel93). He too, decided to make his own crossovers, but his would be longer and better. Due to his love of kids movies from his childhood, Dan felt crossovers needed to be BIG. In other words, the ambitious tuber felt that as many characters as possible could make an already okay film epic.
