### Instruction: How did Pokemon start?
### Input: The Pokémon franchise began as Pocket Monsters: Red and Green (later released outside of Japan as Pokémon Red and Blue), a pair of video games for the original Game Boy handheld system that were developed by Game Freak and published by Nintendo in February 1996. Pokémon soon became a media mix franchise adapted into various different media, with the Pokémon Trading Card Game released in October 1996, the Pokémon Adventures manga first released in Japan in March 1997, and the Pocket Monsters: Original Series released in April 1997. Pocket Pikachu was released in Japan in March 1998, with the first ever Pokémon film, Pokémon: The First Movie, first released in Japan in July 1998.

In 1998, Nintendo spent $25 million promoting Pokémon in the United States in partnership with Hasbro, KFC, and others. Nintendo initially feared that Pokémon was too Japanese for Western tastes but Alfred Kahn, then CEO of 4Kids Entertainment, convinced the company otherwise. The one who spotted Pokémon's potential in the United States was Kahn's colleague Thomas Kenney.

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. The Pokémon Company International oversees all Pokémon licensing outside Asia. In 2006, the franchise celebrated its tenth anniversary with the release of Pokémon Diamond and Pearl. In 2016, the Pokémon Company celebrated Pokémon's 20th anniversary by airing an ad during Super Bowl 50 in January and re-releasing the first Pokémon video games 1996 Game Boy games Pokémon Red, Green (only in Japan), and Blue, and the 1998 Game Boy Color game Pokémon Yellow for the Nintendo 3DS on February 26, 2016. The mobile augmented reality game Pokémon Go was released in July 2016. Pokémon Sun and Moon also released in the same year. The first live-action film in the franchise, Pokémon Detective Pikachu, based on the 2018 Nintendo 3DS spin-off game Detective Pikachu, was released in 2019. The eighth generation of core series games began with Pokémon Sword and Shield, released worldwide on the Nintendo Switch on November 15, 2019.
### Response: Pokemon started out as Pocket Monsters in February of 1996 and was released as a pair of games for the Nintendo Game Boy. It quickly evolved into a mix of media such as the Pokemon Trading Card Game, the Pokemon manga, and the Pokemon anime show in 1997. After Pokemon continued gaining popularity in Japan in 1998, Nintendo spent $25 million to bring Pokemon to the United States, which was also a huge success, and the rest is history.
