Tamagotchi

1996

Tamagotchi is a brand of handheld digital pets marketed since 1996 by Japanese toymaker Bandai, a division of Bandai Namco Holdings. Most Tamagotchi are housed in a small egg-shaped handheld video game with an interface consisting of three buttons, with the goal of raising the pet as it goes through different life stages.
