File 770 is a long-running science fiction fanzine, newszine, and blog site published/administered by Mike Glyer. It is named after the legendary room party held in Room 770 at Nolacon, the 9th World Science Fiction Convention in New Orleans, Louisiana, that upstaged the other events at the 1951 Worldcon.
Glyer started File 770 in 1978 as a mimeographed print fanzine to report on fan clubs, conventions, fannish projects, fans, fanzines and sf awards, and to publish controversial articles. In the 1990s, Glyer moved production of the fanzine to computer desktop publishing, and on January 15, 2008, he began publishing File 770 as a blog on the internet.
File 770 has won the Hugo Award for Best Fanzine six times, in 1984, 1985, 1989, 2000, 2001, 2008, and 2016. In 1984 and again in 2016 both File 770 and its owner/editor Mike Glyer won Hugo Awards (the latter the Hugo Award for Best Fan Writer). File 770 is a frequent nominee in the Best Fanzine category, having made the final Hugo ballot in 1980, 1981, 1982, 1983, 1987, 1988, 1990, 1991, 1992, 1993, 1994, 1995, 1997, 1998, 1999, 2002, 2003, 2004, 2005, 2006, 2009, 2010, 2011, and 2012, in addition to the years in which it was the winner.
A print version of File 770 has been produced every year from 1978 to the present. eFanzines.com began hosting PDF versions of the paper issues in 2005. While File 770 remains a traditional paper fanzine published once or twice a year, much additional news and expanded content is available daily in its on-line blog site version edited by Glyer.
