Alpha Delta Sigma (ADS) is the national honorary society sponsored by the AAF that recognizes and encourages scholastic achievement in advertising studies. The history of the organization dates back to 1913, when the fraternity was founded on the campus of the University of Missouri. In 1969 ADS merged with Gamma Alpha Chi, which was a similar organization for women. ADS merged with the American Advertising Federation in 1973. It is the only national, professional advertising honorary society in American higher education.
Each year, hundreds of students from AAF college chapters are nominated for induction into Alpha Delta Sigma. Nominations are based only on consideration of scholarship and merit and are made once a year by AAF college chapter advisors. If you've got the grades, you're a senior and you're a member of the AAF, then you've got the membership.
