Unhappy with his position on The Critic, Tartakovsky accepted Huber's proposal, and the resulting project, "Changes", was produced as part of Cartoon Network's animation showcase series, World Premiere Toons, debuting on February 26, 1995. Viewers worldwide voted through phone lines, websites, focus groups, and consumer promotions for their favorite short cartoons; Dexter's Laboratory was the first of 16 to earn that vote of approval. Mike Lazzo, then-head of programming for Cartoon Network, said in 1996 that it was his favorite of the 48 shorts that had been produced by that point, commenting that he and colleagues "loved the humor in the brother-versus-sister relationship".
