Major toy makers have banded together to promote the power of playing. The new marketing campaign “The Genius of Play” is an effort from brands and retailers like Mattel, Hasbro, and Toys ‘R’ Us to encourage “open ended” playtime.

Parents are being asked to sign a “Play Pledge” to devote hours of their kids’ time to free-play. (StreamDaily)
