Circus was a monthly American magazine devoted to rock music. It was published from 1966 to 2006. In its heyday the magazine had a full-time editorial staff that included some of the biggest names in rock journalism, such as Paul Nelson, Judy Wieder, David Fricke, and Kurt Loder, and rivaled Rolling Stone in sales and surpassed Creem. In 1974, a sister publication was launched, titled Circus Raves, and by 1977 that venture had been merged into Circus magazine, making Circus a biweekly publication. In 1971 Howard Bloom joined CIRCUS as editor, his tenure lasted until August 1973.
