Soon Ruth and Nestle reached an agreement that would allow them print the recipe on the wrapper of their bars, which now had a scored surface and a special chopper to allow customers to easily cut it into morsels. Ruth received an undisclosed sum and a lifetime supply of chocolate. By 1939 Nestle was selling chocolate chips in packages, and the rest, as they say, is history. Chocolate chip cookies are now America's favourite cookie.
