Norman Bridwell, creator of the popular "Clifford the Big Red Dog" series of children's books turned into a PBS TV show, has died.

Scholastic, his longtime publisher, says Bridwell died Friday in Oak Bluffs, Massachusetts. He lived in Edgartown, Massachusetts.

Starting in 1963 with "Clifford, the Big Red Dog," Bridwell wrote and illustrated more than 40 Clifford books, from "Clifford and the Grouchy Neighbors" to "Clifford Goes to Hollywood." More than 120 million copies have sold worldwide, along with cartoons, a feature film, a musical, stuffed animals, key chains, posters and stickers. Images of Clifford have appeared everywhere from museums to the White House.

Bridwell is survived by his wife, Norma, their daughter, Emily Elizabeth, son, Timothy, and three grandchildren.
