Furby

A Furby is an American electronic robotic toy released in 1998 by Tiger Electronics. It resembles a hamster or owl-like creature and went through a period of being a "must-have" toy following its holiday season launch, with continual sales until 2000. Over 40 million Furbies were sold during the three years of its original production, with 1.8 million sold in 1998, and 14 million in 1999. Its speaking capabilities were translated into 24 languages.

Furbies were the first successful attempt to produce and sell a domestically-aimed robot. A newly purchased Furby starts out speaking entirely Furbish, the unique language that all Furbies use, but is programmed to start using English words and phrases in place of Furbish over time. This process is intended to resemble the process of learning English. The updated Emoto-Tronic Furby, with voice-recognition and more complex facial movements, was sold by Hasbro between 2005-2007. They released another updated Furby with LCD eyes and a mobile app for the holiday season in 2012.
