Teddy Ruxpinis an animatronic talking bear. He was first produced in 1985 by toy manufacturer Worlds of Wonder. Teddy would move his mouth and eyes as he read stories via a standard audio tape deck built into his back.
Teddy Ruxpin used cassette with two different tracks the left track contains the audio, while the right track encodes the toy’s movements. This allowed it to appear that Teddy was reading the story to you.
There was also a companion toy named Grubby which connected to Teddy via a cable; this allowed the two toys to interact.
Teddy Ruxpin was so popular he even had his own T.V. show called: The Adventures of Teddy Ruxpin was a television series that ran from 1987-1988.
Worlds of Wonder went bankrupt and the Teddy Ruxpin property was sold to Hasbro. Ruxpin is still around today using new technologies with memory card replacing cassette tapes.
