Alpha Delta Sigma

Alpha Delta Sigma (ΑΔΣ) was an American men's professional advertising fraternity. It started in 1913 and absorbed Gamma Alpha Chi in 1971. It merged into the American Advertising Federation in 1973.

History
Alpha Delta Sigma was formed as a men's honorary fraternity for the field of advertising at the University of Missouri on 1913-11-14. It was affiliated with the Associated Advertising Clubs of the World, an earlier name for the American Advertising Federation.

The fraternity appears to have fairly quickly repositioned itself as a men's national professional advertising fraternity, with some chapters providing housing for members. As such it joined the Professional Fraternity Association in 1928 as a charter member.

Alpha Delta Sigma absorbed Gamma Alpha Chi, which had also been formed 1920-02-09 at University of Missouri as a female counterpart to Alpha Delta Sigma. The merger occurred on 1971-11-02. In 1964, Alpha Delta Sigma had fifty undergraduate and eleven professional chapters and Gamma Alpha Chi had 37 chapters of which 22 were active.

The merged fraternity was headquartered, briefly, at Texas Tech University. In 1973, the combined fraternity, still named ΑΔΣ and often just "ADS", itself finally merged into the American Advertising Federation. Today the AAF continues to use the name Alpha Delta Sigma for its collegiate programs and as a subsidiary national honor society for the field.
