After "Seventeen" was launched in New York City on September 1944, Estelle Ellis Rubenstein, the magazine's promotion director, introduced advertisers to the life of teenaged girls through "Teena", selling advertising in "Seventeen" at the same time. From 1945 to 1946, the magazine surveyed teen girls to better understand the magazine's audience. The magazine became an important source of information to manufacturers seeking guidance on how to satisfy consumer demand among teenagers. Today, the magazine entertains and promotes self-confidence in young women.
