Santa’s elves are real, and they can be found not in the North Pole, but inside the toy factories of the toy factories scattered in all four corners of the world. One of the largest toy companies is Mattel, which is headquartered in El Segundo, California. It’s here where some of the most iconic toy brands are designed and conceived, such as all things Fisher-Price, Barbie dolls, Monster High dolls, Hot Wheels and Matchbox toys, Masters of the Universe, American Girl dolls, numerous board games, and all WWE Toys. This weekend Mo Rocca will take us inside Mattel’s epic headquarters, where he recently got a private tour. Earlier today CBS This Morning previewed Rocca’s Mattel tour and you can watch it in full below. Mattel was founded in 1945 and is listed at #387 on the Fortune 500, with an annual revenue of $6.2 billion.
