Slinky (also known as Spring) is a toy metal spring that tumbles end over end down stairs and even "walks". It was invented by Richard James in 1943, and quickly became a bestseller. Other Slinky toys were developed such as the Slinky Dog and the Slinky Train. Company president Betty James has always kept the toy's price low so children could buy it. It originally sold for $1. Slinky has received many toy industry awards and honors over the years. Its television jingle is the longest running jingle in advertising history.
