The Detroit Triple Fan Fair (DTFF) was a multigenre convention generally held annually in Detroit, Michigan, from 1965 to 1977. It is credited as being the first regularly held convention featuring comic books as a major component. The Triple Fan Fair also gave balanced coverage to historic film showings and science-fiction literature, in a manner that provided a template for many future convention organizers — most of which have yet to attain the same level of equal service to this sort of linked fan base.
