American Girl, Inc. is one of the most well respected brands in the U.S. toy and children's book industries. Headquartered in Middleton, Wisconsin, the company has as its primary focus the positive growth and well-being of girls ages three to 12. The corporate mission is simple: "to celebrate girls." When author and educator Pleasant Rowland founded the company in 1986, its only product line was historical fiction series books and high quality, 18-inch dolls representing each of the three heroines in the series books. The company has since expanded to include additional doll and character toy lines, contemporary clothing for girls, multiple retail stores, and a publishing business that ranks among the top 15 children's book publishers in the country. American Girl publishes a bimonthly magazine, as well as an expansive collection of historical fiction, and contemporary fiction and nonfiction titles. Since 1998, the company has been a wholly owned subsidiary of Mattel, Inc.
