Published by Andrew Porter between 1963 and 1984, Algol tied for a Hugo Award for Best Fanzine in 1974 with Richard E. Geis' Science Fiction Review. In all the fanzine received five other Hugo nominations (1973, 1975, 1976, and 1981). Initially a two-page publication printed by spirit duplicator, Porter expanded the number of pages rapidly, moving to offset covers, then eventually adding mimeographed contents. Its 16th issue was a fully printed publication, and with issue 24 the zine was given a full color cover. At its peak Algol's circulation was around 7,000.
Over the years the columnists included Ted White, Richard A. Lupoff, Susan Wood, Vincent Di Fate, Robert Silverberg, Frederik Pohl, Joe Sanders and Bhob Stewart. Other contributors included A. Bertram Chandler.
In 1979 Porter changed the name of the zine to Starship.
