The Jameses went into the Slinky business. They invented a machine that could produce a Slinky from 80 feet of steel wire within 10 seconds. A huge advertising campaign was launched in America. James showed television viewers how Slinky worked. Other Slinky toys manufactured during the 1950s were the Slinky Dog, Suzie the Slinky Worm, and a pair of eyeglasses with eyeballs dangling at the end of two Slinkys. Other companies were granted licenses to produce Slinky toys.
