Mattel Inc /de/
A global toy and family entertainment company, Mattel makes beloved brands including Barbie, Hot Wheels, Fisher-Price, American Girl, Thomas & Friends, Masters of the Universe, UNO, and MEGA. It was founded in 1945 in Los Angeles by Harold "Matt" Matson, Elliot Handler, and Ruth Handler, who combined "Matt" and "El" from the founders' names to create the company name. Fun fact: the Barbie doll, launched in 1959, was named after Ruth Handler's daughter Barbara, and Barbie's boyfriend Ken was named after the Handlers' son Kenneth.
