Since then Square has developed dozens of popular games in collaboration with many others (Disney, Electronic Arts, others) for various consoles and platforms, and has branched out into several subsidaries that assist in various development areas for the gaming industry. In 2001, Square even produced a fully-CGI-animated movie, Final Fantasy: The Spirits Within, in the spirit of its popular Final Fantasy games.
In 2003, in order to cut costs and become more competitive, Square Co., Ltd. and its subsidaries merged with Enix Corporation (another successful name in the gaming industry) to form Square Enix. The company now continues to operate under that name.
