Pokémon is a media franchise owned by The Pokémon Company, and created by Satoshi Tajiri in 1996. It is centered around fictional creatures called "Pokémon", which humans capture and train to fight each other for sport. The franchise began as a pair of video games for the original Game Boy, developed by Game Freak and published by Nintendo. The franchise now spans video games, trading card games, animated television shows and movies, comic books, and toys. Pokémon is the second-most successful and lucrative video game-based media franchise in the world, behind only Nintendo's Mario franchise. The franchise celebrated its tenth anniversary in 2006. Cumulative sales of the video games have reached more than 200 million copies. In November 2005, 4Kids Entertainment, which had managed the non-game related licensing of Pokémon, announced that it had agreed not to renew the Pokémon representation agreement. Pokémon USA Inc., a subsidiary of Japan's Pokémon Co., now oversees all Pokémon licensing outside of Asia.
