"The Little Mermaid", Disney's first animated fairy tale since "Sleeping Beauty" (1959), is an important film in animation history for many reasons. Chief among these are its re-establishment of animation as a profitable venture for The Walt Disney Company, as the company's theme parks, television productions, and live-action features had overshadowed the animated output since the 1950s. "The Little Mermaid" was the second film, following "Oliver & Company", produced after Disney began expanding its animated output following its successful live action/animated film "Who Framed Roger Rabbit", and became Disney's first animated major box office and critical hit since "The Rescuers" in 1977. Walt Disney Feature Animation was further expanded as a result of "The Little Mermaid" and increasingly successful follow-ups — "Beauty and the Beast" (1991), "Aladdin" (1992), and "The Lion King" (1994). The staff increased from 300 members in 1988 to 2,200 in 1999 spread across three studios in Burbank, California, Lake Buena Vista, Florida, and Montreuil, Seine-Saint-Denis, France.
