Toymaker Mattel, based in El Segundo, saw its net income rise 23 percent in the third quarter. Sales were driven in large part by its line of dolls. Sales of Barbie dolls rose 6 percent worldwide; other doll sales rose 7 percent, driven by Mattel’s Disney Princess line and its new Monster High dolls. The American Girl line rose 2 percent. Sales of Hot Wheels and Fisher-Price toys both fell, however. Mattel also took advantage of a tax break in the third quarter.
