Furby (plural Furbys or Furbies, according to Tiger. Co.) is an electronic toy, more specifically, a robot, made by Tiger Electronics which went through a period of being a "must-have" toy following its launch in the holiday season of 1998, with continual sales until 2000. Furby sold 1.8 million units in 1998, and 14 million units in 1999. Altogether in its three years of original production, over 40 million units were sold, and its speaking capabilities were translated into 24 languages. Furbys were the first successful attempt to produce and sell a domestically-aimed robot. A newly purchased Furby initially starts out speaking Furbish, a unique language that all Furbys are programmed to use, but their Furbish usage declines as they gradually start using English. English is learned automatically, no matter what culture they are nurtured in. In 2005, new Furbys were released, with voice-recognition and more complex facial movements, among many other changes and improvements. The Emoto-Tronic Furbies (Furby, Furby Baby, and Funky Furby) continued to be sold until late 2007, when these toys became extremely rare.
Mine was demonically possessed. It made a crazy computerized shrieking sound constantly and we couldn't reset it. So, we took it apart. Cyber-Furby! From then on, we always found it more fun to disassemble them.
