Founded by Benjamin W. Sangor, ACG was co-owned by Fred Iger from 1948 to 1967. Iger's father-in-law, Harry Donenfeld, head of National Periodical Publications (later known as DC Comics), was also a co-owner in the early 1960s (though Donenfeld was severely incapacitated and out of the business after an accident in 1962). ACG was distributed by Independent News Company, which also distributed (and was part of the same company as) DC.
