Randall Munroe's xkcd epic "Time" won the 2014 Hugo Award for Best Graphic Story, presented Sunday in London as part of Loncon 3, the 72nd World Science Fiction Convention.

Presented annually since 1955 by the World Science Fiction Society, the Hugo is among science fiction’s most prestigious awards.

Author Cory Doctorow accepted on the award on Munroe's behalf, and donned a cape and goggles at the cartoonist's request. According to io9.com, Munroe's speech indicated he'd asked Doctorow to read it as one word per hour, reflecting the pace of the animated comic, which updated initially ever half-hour and then every hour over the course of 123 days. (The story has its own Wikipedia entry.)

Other nominees in the category were: Girl Genius, Vol. 13: Agatha Heterodyne & The Sleeping City, by Phil Foglio, Kaja Foglio and Cheyenne Wright (Airship Entertainment); “The Girl Who Loved Doctor Who,” by Paul Cornell and  Jimmy Broxton (Doctor Who Special 2013, IDW Publishing); The Meathouse Man, adapted from the story by George R.R. Martin and illustrated by Raya Golden (Jet City Comics); and Saga, Vol. 2, by Brian K. Vaughan and Fiona Staples (Image Comics ).

Munroe’s What If?: Serious Answers to Absurd Hypothetical Questions, based on his popular blog, will be released next month by Houghton Mifflin Harcourt.
