The Barbie doll debuted on March 9, 1959, going on to become the company's best-selling toy in history. Mattel would ultimately acquire Fisher-Price on August 20, 1993. The Fisher-Price Corn Popper, and the Xylophone was released in 1957. Mattel started television advertisement when it became the first sponsor of the Mickey Mouse Club TV series.

In 1950, the Magic 8-Ball, currently owned by Mattel themselves, was invented by Albert C. The company was incorporated in Hawthorne, California in 1948. In 1947, the company had its first successful toy, a ukulele called "Uke-A-Doodle".

Matson sold his share and stake to the Handlers due to poor health the following year, with Handler's wife, Ruth, taking over his stake.

The company began selling picture frames and later dollhouse furniture out of the scraps from those frames. The company name chosen is a portmanteau of the surname of Matson and first name of Elliot, with former chairman and CEO Bob Eckert revealing at a 2013 Christmas Day Peninsula Seniors lecture that the founders, according to Elliot, couldn't fit Ruth's name into that of their company. Businessman Harold "Matt" Matson and the husband-and-wife duo of Elliot and Ruth Handler founded Mattel as Mattel Creations in January 1945 in a garage in Los Angeles.
