Seventeen is an American magazine for teenagers. It was the first teen magazine established in the United States. The magazine's reader base is 12–19 year-old females. It began as a publication geared towards inspiring teen girls to become role models in work and citizenship. Soon after its debut, Seventeen took a more fashion and romance-oriented approach in presenting their material, while still maintaining their model of promoting self-confidence in young women. It was first published in September 1944 by Walter Annenberg's Triangle Publications.
