text: At the same time, Canadian folk music became more formalized and commercialized with the rise of specialized folk festivals (beginning with the Miramichi Folksong Festival in 1958), increased radio airplay on rock, pop, and easy listening radio stations, the introduction of the Juno Award for Folk Artist of the Year in 1971, and even an academic journal the Canadian Folk Music Journal in 1973.
