Seventeen is an American
magazine for teenagers. It was the first teen magazine established in the United States. The magazine's reader base is 10-to-19-year-old females. It began as a publication geared towards inspiring teen girls to become model workers and citizens. Soon after its debut,
Seventeen took a more fashion and romance-oriented approach in presenting its material while promoting self-confidence in young women. It was first published in September 1944 by
Walter Annenberg's
Triangle Publications.
