A few months ago, Mattel’s revenues were just fifty million dollars behind Hasbro’s. But now that Hasbro’s swallowed Tonka—the classic maker of Nerf, Play-Doh, and Monopoly—Mattel is half a billion dollars behind, and CEO John Amerman isn’t happy about it. Ever since Hasbro turned British fashion doll Sindy into a Barbie lookalike, the two toymakers have been at war. Now Amerman is looking to make a couple strategic acquisitions: one to put Mattel back in pole position, and the other, to spite Hasbro.
