Often imitated (looking at you, Nano Pets), Tamagotchis were tops. Kitties! Puppies! Babies! Aliens? Whatever these beings technically were, they taught '90s kids and teens to care for another "living" thing.
Talkboy started as a nonworking prop for the film "Home Alone 2: Lost in New York." Hasbro was happily forced to create it due to overwhelming demand. There was even a Talkgirl, because how could a little girl enjoy something called "-boy"? Ahem.
The SNES console was introduced at the beginning of the decade. Original Nintendo game cartridges weren't compatible, so '90s gamers got all new games. Bonus for them, bummer for their parents' wallets.
Speaking of Cher from "Clueless," remember that sweet closet system she had on her computer? Well Barbie had the same thing on CD-ROM back in the '90s. The program allowed users to select coordinating outfits from her wardrobe.
Around the same time we started carrying CD Walkmans around, there came Hit Clips (or Kid Clips for the really little ones). You couldn't hear full songs, but you could hear 1 minute of your favorite pop songs. Isn't that just as good? Well, if you're three, yes.
