Play-Doh will soon be squeezed out of a factory in the U.S. again, as Hasbro Inc. brings manufacturing of the popular moldable clay back to America for the first time in years. Hasbro said it is working with a manufacturing partner to make Play-Doh at a facility in East Longmeadow, Mass., starting in the second half of 2018. Although the preschool clay was invented in Cincinnati in the 1950s, it hasn't been made in the U.S. since 2004.
