The Tamagotchi (たまごっち?) is a handheld digital pet, created in Japan by Akihiro Yokoi of WiZ and Aki Maita of Bandai. It was first sold by Bandai on November 23, 1996 in Japan. As of 2010, over 76 million Tamagotchis have been sold world-wide.[1] Most Tamagotchi are housed in a small egg-shaped computer with an interface usually consisting of three buttons, although the number of buttons may vary.
