"Pokémon exemplifies how the supersystem works. Pokémon was first created as Game Boy software. It then almost simultaneously appeared as a serial comic in Koro Koro, a monthly comic magazine targeted to boys, as a part of an overall marketing strategy. The positive reception of the computer game and the comics led to the creation of and further interlinking with trading cards, a TV series, films, and, eventually, various merchandise featuring popular Pokémon characters. Within this multiple product, multimedia business, Pokémon constantly reinvented itself. For example, for the creation of the comics and the TV cartoon, Pippii and Pikachi were chosen as the main Pokémon characters, respectively. Neither Pippi nor Pikachu was a main character in the original Game Boy software. (Pippi (in English, Clefairy) was selected as the main Pokémon character to make the comic book series more "engaging." However, in order to attract younger and female viewers as well as their mothers, Pikachu replaced Pippi as the central character when the Pokémon TV series was introduced in 1997. the pink Pippi was replaced by the yellow cuddlier Pikachu, whom the producers believed would seem like a more familiar and intimate pet to child viewers. There were other reasons as well for the producers' choice of yellow. Because yellow is one of the three basic colors, it is easy for children to recognize Pikachu even from a distance. Furthermore, the only competing yellow character is Winnie the Pooh (Kubo 2000a; 2000b). As we can see in the case of the emergence of Pikachu as the key character, the development of the Pokémon supersystem was achieved through trial and error in the Japanese market. But once the components of the supersystem were put together in Japan, they could be used systematically to introduce Pokémon in global markets. The overseas promotion of Pokémon was forged from the outset by a subtly packaged amalgamation of cartoons, comics, trading cards, feature films, character merchandise, and Game Boy games."
