Pokemon Day commemorates February 27, 1996, when Pocket Monsters Red and Green, the first Pokemon games, launched for the Game Boy in Japan. They were created by Satoshi Tajiri and developed by his studio Game Freak with Nintendo's support, and The Pokemon Company now brands February 27 each year as Pokemon Day, usually headlined by a Pokemon Presents broadcast.
Red and Green, February 27, 1996
The first two games, Pocket Monsters Red and Pocket Monsters Green, launched for the Game Boy in Japan on February 27, 1996. The two versions held slightly different creatures on purpose, so finishing the collection meant trading with someone who owned the other game.
That single design choice turned a solo game into a schoolyard economy. Children linked their Game Boys with a cable and swapped creatures they could not otherwise get, and the games sold by word of mouth.
