stylistic gimmicks or literary games. Jonathan Lethem, in a 1998 essay in the Village Voice entitled "Close Encounters: The Squandered Promise of Science Fiction," suggested that the point in 1973 when Thomas Pynchon's Gravity's Rainbow was nominated for the Nebula Award and was passed over in favor of Clarke's Rendezvous with Rama, stands as "a hidden tombstone marking the death of the hope that SF was about to merge with the mainstream." In the same year science fiction author and physicist Gregory Benford wrote: "SF is perhaps the defining genre of the twentieth century, although its conquering armies are still camped outside the Rome of the literary citadels." Community Authors Science fiction is being written, and has been written, by diverse authors from around the world. According to 2013 statistics by the science fiction publisher Tor Books, men outnumber women by 78% to 22% among submissions to the publisher. A controversy about voting slates in the 2015 Hugo Awards highlighted tensions in the science fiction community between a trend of increasingly diverse works and authors being honored by awards, and reaction by groups of authors and fans who preferred what they considered more "traditional" science fiction. Awards Among the most respected and well-known awards for science fiction are the Hugo Award for literature, presented by the World Science Fiction Society at Worldcon, and voted on by fans; the Nebula Award for literature, presented by the Science Fiction and Fantasy Writers of America, and voted on by the community of authors; the John W. Campbell Memorial Award for Best Science Fiction Novel, presented by a jury of writers; and the Theodore Sturgeon Memorial Award for short fiction, presented by a jury. One notable award for science fiction films and TV programs is the Saturn Award, which is presented annually by The Academy of Science Fiction, Fantasy, and Horror Films. There are other national awards, like Canada's Prix Aurora Awards, regional awards, like the Endeavour Award presented at Orycon for works from the U.S. Pacific Northwest, and special interest or subgenre awards such as the Chesley Award for art, presented by the Association of Science Fiction & Fantasy Artists, or the World Fantasy Award for fantasy. Magazines may organize reader polls, notably the Locus Award. Conventions Conventions (in fandom, often shortened as "cons," such as "comic-con") are held in cities around the world, catering to a local, regional, national, or international membership.
