Broadside magazine was a small mimeographed publication founded in 1962 by Agnes "Sis" Cunningham and her husband, Gordon Friesen. Hugely influential in the folk-revival, it was often controversial. Issues of what is folk music, what is folk rock, and who is folk were roundly discussed and debated. At the same time, Broadside nurtured and promoted important singers of the era. By the end of the 1970s, Broadside had essentially ceased publication.
