# Asimov's Science Fiction

Asimov's Science Fiction is an American science fiction magazine edited by Sheila Williams and published by Dell Magazines, which is owned by Penny Press. It was launched as a quarterly by Davis Publications in 1977, after obtaining Isaac Asimov's consent for the use of his name. It was originally titled Isaac Asimov's Science Fiction Magazine, and was quickly successful, reaching a circulation of over 100,000 within a year, and switching to monthly publication within a couple of years. George H. Scithers, the first editor, published many new writers who went on to be successful in the genre. Scithers favored traditional stories without sex or obscenity; along with frequent humorous stories, this gave Asimov's a reputation for printing juvenile fiction, despite its success. Asimov was not part of the editorial team, but wrote editorials for the magazine.
Scithers was fired in 1982, and his replacement, Kathleen Moloney, only lasted a year. Shawna McCarthy took over as editor in 1983, and quickly relaxed the strictures on the kind of fiction Asimov's was willing to publish. "Her Furry Face", by Leigh Kennedy, with a plot that involved sex with an intelligent orangutan, scandalized some readers, as did other stories involving sex or violence. Asimov defended McCarthy's choices in an editorial, and "Her Furry Face" was nominated for a Nebula Award. McCarthy transformed the magazine into a leading market for science fiction writers, and more award-winning stories appeared, including fiction by Frederik Pohl, Robert Silverberg, Lucius Shepard, and John Varley.
Gardner Dozois took over as editor in 1985 and stayed for nearly twenty years. Asimov's continued to be a prestigious market and several award-winning stories appeared during Dozois's tenure, including Lucius Shepard's "R&R"; Orson Scott Card's "Hatrack River"; Pat Murphy's "Rachel in Love"; Suzy McKee Charnas's "Boobs"; and Terry Bisson's "Bears Discover Fire". Mike Ashley, a historian of science fiction magazines, describes Dozois's time at Asimov's as "one of the greatest of all editorial careers". Dozois was succeeded by Sheila Williams in 2004.
Davis sold the magazine to Dell Magazines in 1992, and Dell was acquired by Penny Press in 1996. Asimov's switched to bimonthly publication in 2017. Circulation declined steadily over the life of the magazine and as of 2020 it was below 20,000, more than half of that coming from online subscriptions.

## Publication history

In February 1976, Isaac Asimov visited the offices of Davis Publications in New York to drop off a story he was submitting to Ellery Queen's Mystery Magazine. Joel Davis, the publisher, had recently acquired Alfred Hitchcock's Mystery Magazine, and was interested in adding new fiction magazines to his list. One of his employees had gone to a Star Trek convention with their children, and had told Davis how much the children had enjoyed it. This prompted Davis to talk to Asimov about a new science fiction magazine, and Davis asked Asimov if he could use his name as part of the magazine's title. Asimov was concerned about the potential impact on two of the major science fiction magazines of the day, Analog Science Fiction/Science Fact, and The Magazine of Fantasy & Science Fiction (F&SF), both of which were edited by friends of his, Ben Bova and Ed Ferman. Davis argued that a new magazine would be good for the field, and Bova and Ferman both told Asimov that they agreed with Davis. Asimov agreed to go ahead with the plan on condition that he did not act as editor. Asimov wrote a regular science column for F&SF, which he continued, but Davis asked him not to submit fiction to competing magazines.

George Scithers was soon hired to fill the editorial role, with Gardner Dozois as associate editor; Dozois only stayed a year, as he and Scithers did not agree on what kind of stories should be accepted. Davis initially committed to three quarterly issues, the first of which was dated Spring 1977, and appeared on December 16, 1976. The magazine was immediately successful, circulation reaching 108,843 for the first year, a little higher than Analog's. Circulation was helped by the distribution network that Davis Publications already had access to for its existing magazines, with robust newsstand distribution. Paperback anthologies of stories from the magazine were assembled, starting at the end of 1977; these were profitable and also attracted new readers. The magazine's success persuaded Davis to move to a bimonthly schedule for 1978, and to monthly starting with the January 1979 issue. Davis decided to launch a second magazine, Asimov's SF Adventure Magazine, targeted to a younger audience. The first issue was dated Fall 1978. Four quarterly issues appeared, but sales were weak, and a planned fifth issue never appeared.

Davis moved all four of his fiction magazines to a four-weekly schedule in 1981, meaning there were thirteen issues per year. The change took effect at Asimov's with the January issue, which was dated January 19, 1981. This led to newsstand vendors removing the magazine more quickly, since the date implied that it was a weekly magazine. The cover date was changed back to the current month starting with the April 1982 issue, but the new schedule remained in place, with "Mid-December" issues for more than a decade thereafter.
Davis launched two more magazines in 1981: Crime Digest and Science Fiction Digest; these carried book excerpts and publishing news. Scithers had been announced as the editor of Science Fiction Digest, but when it was launched Shawna McCarthy was given the editorial role. This may have been because Scithers was based in Philadelphia, with a local team of first readers to help read the incoming manuscripts, and Davis wanted an editor who was in the New York office five days a week. According to Asimov, Scithers and Davis never got along very well. Scithers's refusal to move to New York made matters worse, and there were other sources of tension: Davis appointed Carol Gross as executive director in charge of marketing and production, and Gross instigated a redesign of the magazine and took control of the art department away from Scithers. In December 1981, Scithers was fired.
Scithers's replacement was Kathleen Moloney, who was hired away from Bantam where she had been a book editor. At first Moloney edited the stories heavily without consulting the authors until the galley proofs were printed, against McCarthy's advice. After pushback from the authors, Moloney turned over manuscript editing to McCarthy. Moloney was hired away by Times Books later that year, and replaced by McCarthy, who was told that Asimov had insisted that she become the next editor if the magazine wanted to keep his name. Her first issue was dated January 1983. She was succeeded in May 1985 by Gardner Dozois, though he was not credited on the masthead until January 1986.

Circulation had declined from its first-year peak to about 80,000 by the time Dozois became editor. The 1987 recession caused Davis Publications financial problems, and Davis decided to sell all four fiction magazines. While he searched for a buyer, changes were made to increase profitability: two issues per year were doubled in size and increased in price. The magazines were bought in January 1992 by Bantam-Doubleday-Dell, and became part of Dell Magazines. The title was shortened that November to Asimov's Science Fiction.
In September 1996 Dell Magazines was sold to Penny Press. The schedule returned to monthly and the October and November issues were combined, so that only eleven rather than thirteen issues appeared per year. The page count was cut, and prices increased. In June 1998 the size was increased from a standard digest size of 7.5 in × 5 in (19 cm × 13 cm) to 8.25 in × 5.25 in (21.0 cm × 13.3 cm) to match other Penny Press magazines, which made printing and binding more efficient. The page count dropped at the same time, but the changes were announced as an increase in total text of 10%, with no change in price. However, a year later the price rose again. Circulation dropped over 30% over the first four years of Penny Press's ownership, from about 46,000 to under 32,000, probably partly because of these changes. Most of the decline was in subscription sales, though profitability was helped by subscribers who came through the magazine's website, which had been started in 1998, instead of through a third party that took a commission from the subscription price.
Dozois gave up the editorship in 2004, and was succeeded by Sheila Williams, whose first issue was dated December of that year. The number of issues per year was reduced to ten starting in 2004, with the April and May issues combined into a double-sized issue. In 2008 the size was increased again, to 8.5 in × 5.75 in (21.6 cm × 14.6 cm), to make the magazine more prominent on newsstands. From January 2017, the schedule was changed to six bimonthly double-sized issues per year.
In February 2025, the magazine was purchased by a group of investors led by Steven Salpeter, president of literary and IP development at Assemble Media.

## Contents and reception
### Scithers (1977–1982)

Asimov and Scithers agreed at the launch of the magazine on their goals for the magazine. In an editorial in the first issue, Asimov said "we will lean toward hard science fiction, and toward the reasonably straightforward in the way of style ... We will have humorous stories and we will have an occasional unclassifiable story". Mike Ashley, a historian of science fiction, summarizes the plans for the magazine: "It was not to be one full of stories trying to put the world to rights, nor to be full of experimental or New Wave material."
The first issue included stories by Asimov, Arthur C. Clarke, Jonathan Fast, and Fred Saberhagen, and an excerpt from Gordon R. Dickson's novel Time Storm which would be published later that year. John Varley contributed two stories: "Good-Bye, Robinson Crusoe", one of his Eight Worlds stories; and (under a pseudonym) "Air Raid", which was turned into a film, Millennium, in 1989. Asimov's soon became known for humorous stories. The only touch of humor in the first issue was Clarke's story, "Quarantine", which was a very short story originally written to fit on a postcard, but more quickly appeared. Two stories by Asimov based on puns appeared in the second issue, and the third issue saw the re-appearance of Reginald Bretnor's "Feghoot" series of punning stories that had appeared in The Magazine of Fantasy & Science Fiction and Venture Science Fiction decades earlier. More "spoofs or parodies and occasional limericks" appeared which "threatened to overshadow the more serious fiction", according to science fiction historian Mike Ashley. For example "Bat Durston: Space Marshal" by G. Richard Bozarth was a parody, inspired by an advertisement that had appeared on the back cover of Galaxy Science Fiction in the 1950s; Ashley points out that new readers might have thought it was intended as a serious story. Allied with some stories clearly written for younger readers, these stories gave the impression that the magazine was not aimed at an adult audience. Orson Scott Card commented in an early review of Asimov's that it had "tapped a juvenile market that none of the other magazines was reaching", and other reviewers made similar comments. As a result, some writers did not submit manuscripts to Asimov's despite the competitive rates of pay. Ashley suggests that when Dozois left the editorial staff after only a year, it was because he wanted to acquire stories that were more sophisticated than the material Scithers preferred.
Scithers bought the first published stories of many writers over his tenure, and his habit of announcing in the magazine when a story was a first sale may have encouraged more submissions from new writers. His discoveries included Barry Longyear and Diana Paxson, and several more authors who had only just started their careers began selling regularly to Scithers, including John M. Ford, Nancy Kress, and Somtow Sucharitkul. Longyear's "Circus World" series began in the magazine, but his best-received story was "Enemy Mine", which appeared in the September 1979 issue and won both the Hugo and Nebula Awards. Some well-established writers appeared in the magazine, despite its reputation as a juvenile market: Varley contributed "The Barbie Murders" in early 1978, and Michael Bishop, Brian Aldiss, Tanith Lee, Robert Silverberg, Gene Wolfe, and James Tiptree, Jr, all appeared during Scither's tenure. Scithers won the Hugo Award for Best Professional Editor in 1978, the first year in which he was eligible, and again in 1980.
Asimov's readership included many who were new to the field, and many more who had given up on the other major science fiction magazines. This combination was a good fit for Scithers's approach: traditional stories, without sex or profanity: "nothing too challenging or revolutionary", in Ashley's words. Some veteran science fiction writers such as L. Sprague de Camp, Hal Clement, and Jack Williamson fit in well with Scithers's constraints, producing material that could have been printed in a 1950s magazine, but Frederik Pohl's "Like unto the Locust", which appeared in 1979, did not. Letters poured in objecting to the profanity that appeared in the story. Scithers responded: "... we want to apologize for not copy-editing this installment as well as we should. It's not our intention to use language quite that strong when we (and the authors) can avoid doing so." Evidence from circulation figures suggest that longtime readers of science fiction were becoming a smaller percentage of Asimov's readership, and Ashley describes the result as stagnation: Scithers's had "dumbed down" the material to please the new readers Asimov's was attracting, but as a result the magazine was becoming isolated within the field. John Shirley criticized the magazine in 1979 as "a fog of predictability, formula, and done-to-death techno-bullshit imagery", adding a year later that Scithers was playing it safe, "And when you're that safe, you're schlock .... People think that this is science fiction and I fear that it is a major neutralizing influence on the field." Ashley argues that the magazine's success cannot be ascribed only to the unchallenging fiction it printed; Asimov's name drew in many fans of his books, and Davis Publications' marketing experience helped as well.
Although Asimov had no editorial role, he was named the magazine's editorial director and wrote many editorials for it. A puzzle column by Martin Gardner began in the first issue. A book review column, by Charles N. Brown, followed in the second issue; Brown was replaced by Baird Searles in May 1979.

### Moloney (1982)

Moloney had no background in science fiction, but soon realized that Asimov's name was a significant asset. She persuaded Asimov to submit his Azazel stories, which he had begun publishing in the competing magazines, to Asimov's, starting with "To the Victor" in July 1982. Moloney added two non-fiction columns: a profile of a writer, often written by Charles Platt, and an opinion column called Viewpoint. A cartoon series, "Mooney's Module", began, and she commissioned crosswords from Merl Reagle. Reader reaction was mixed, some letters complaining about the non-fiction columns taking up space that could have been used for another story. Moloney's impact on the fiction was limited; negative author reaction to her habit of heavily editing their manuscripts, and advice from McCarthy, led to her giving McCarthy a good deal of control over the fiction. Two well-known stories published during Moloney's tenure were Connie Willis's "A Letter from the Clearys", and David Brin's "The Postman", which later formed the basis of a novel and film of the same name.

### McCarthy (1983–1985)

McCarthy took over fully as editor with Moloney's departure at the end of 1982. The February 1983 issue, the second one with McCarthy's name on the masthead, included Greg Bear's novella "Hardfought", which went on to win the Nebula Award. McCarthy was willing to expand the range of fiction the magazine published, and most readers who wrote in agreed that the prohibition on sex and violence could be relaxed, but Davis Publications did not want to risk alienating the young readers whom they knew formed part of the magazine's audience. McCarthy was unable to resolve this conflict for Connie Willis's "All My Darling Daughters", a story featuring "lesbianism and bestiality and incest", in Willis's words, and it never saw print in Asimov's, appearing in Willis's short story collection Fire Watch instead. McCarthy continued to be open to a broader range of fiction than Scithers had been, and at the end of the year published Leigh Kennedy's "Her Furry Face", with a plot that involved sex with an intelligent orangutan. Two stories in the next issue featuring street violence: Norman Spinrad's "Street Meat", and Octavia Butler's "Speech Sounds". McCarthy introduced "Street Meat" by saying "What follows is not for the faint of heart." Kennedy's story led to many complaints and canceled subscriptions, and McCarthy was asked by Davis to be cautious in future, but the stories were well received: "Speech Sounds" won that year's short story Hugo Award and "Her Furry Face" was nominated for the Nebula Award. Asimov defended the publication of "Her Furry Face" in a subsequent editorial. McCarthy commented afterwards that "the long-time Asimov fans were shocked and we hadn't gotten enough new readers yet". Other stories from McCarthy's first year in charge included Dozois's "The Peacemaker", in the August 1983 issue, which won the Nebula Award.
Well-received stories from 1984, McCarthy's second year in charge, included Lucius Shepard's "A Traveler's Tale", John Kessel's "The Big Dream", and Varley's "Press Enter■", which won both the Hugo and Nebula Awards. Ashley singles out Octavia Butler's "Bloodchild", in the June 1984 issue, as "arguably the single most important story publiished during McCarthy's editorship". The story was about a race of insectoid aliens. The human protagonist has a relationship with one of the aliens, and agrees to allow the alien to lay their eggs in his body. "Bloodchild" won the Hugo and Nebula Awards and appeared in all that year's "Best of Science Fiction" anthologies. Reader reaction in Asimov's was positive, and a 1995 review of Butler's collection Bloodchild and Other Stories described the story as "one of the genre's undisputed classics".
McCarthy's effect on the magazine was quickly noticed. Dozois's summary of 1983 in science fiction commented that "If there was an award for the most dramatically improved magazine of the year, it would have to go to Isaac Asimov's Science Fiction Magazine, and the credit for that sea change seems to belong almost entirely to new editor Shawna McCarthy." Writers began to make Asimov's their first market to submit to, and 1985 saw more award-winning stories as a result: Pohl's "Fermi and Frost"; Silverberg's "Sailing to Byzantium"; Roger Zelazny's "24 Views of Mount Fuji, by Hokusai"; and "Portraits of His Children", by George R. R. Martin. For the three years that McCarthy edited, Asimov's dominated the annual science fiction awards, accounting for almost a third of the nominations for Hugo, Nebula, and Locus Awards, and inclusions in the annual "Year's Best" anthologies.
McCarthy discovered or encouraged many new writers, including Mary Gentle, Nina Kiriki Hoffman, Paul J. McAuley, and Karen Joy Fowler. She won the Hugo Award for Best Professional Editor in 1984.

### Dozois (1986–2004)

When Dozois took over the editorship of Asimov's, McCarthy's work had changed the image of the magazine, and Dozois worked to solidify the impression that, in Ashley's words, "Asimov's was where the 'cutting edge' work in the field was appearing, so that authors would be eager to appear there". Dozois's tenure began as cyberpunk (a subgenre of science fiction focused on the consequences of virtual reality and computer technology) was becoming more popular, and cyberpunk fiction soon appeared: in January 1986, Dozois serialized William Gibson's Count Zero, the sequel to Gibson's debut novel, Neuromancer, and he also printed Pat Cadigan's "Pretty Boy Crossover". Asimov's did not focus solely on cyberpunk, though; Dozois printed a wide variety of speculative fiction. Stories from Dozois's first year include Lucius Shepard's "R&R", which won the Nebula; Orson Scott Card's "Hatrack River", which won the World Fantasy Award; and Kate Wilhelm's "The Girl Who Fell From the Sky", which won a Nebula. Pat Murphy and Kim Stanley Robinson began selling regularly to Dozois; Murphy's "Rachel in Love", in the April 1987 issue, about a teenage girl's personality in a chimpanzee's body, won a Nebula and a Locus Award, and Robinson's "The Blind Geometer", in the August issue, also won a Nebula.
Asimov's had never run serials before Count Zero, and there was some resistance from the readers, since in most cases the novel would also be published in book form. Dozois persisted for a while, with Michael Swanwick's Vacuum Flowers beginning serialization in the Mid-December 1986 issue. Harlan Ellison's script for a film based on Asimov's robot short stories was serialized at the end of 1987 as I Robot: The Movie, and Swanwick's Stations of the Tide ran in the Mid-December 1990 and January 1991 issues, but those were the last to appear.
A regular feature of the magazine was a long novella as the lead story. Orson Scott Card's "Eye for Eye", which won a Hugo, appeared in this slot, as did Megan Lindholm's "A Touch of Lavender", voted the most popular novella of 1989 by Asimov's readers. Dozois also published shorter fiction: short stories from Dozoi's tenure at Asimov's that won the Hugo or Nebula awards include Suzy McKee Charnas's "Boobs" (1989), Terry Bisson's "Bears Discover Fire" (1990), and Michael Swanwick's "The Very Pulse of the Machine". Newer writers discovered by Dozois included Allen Steele and Mary Rosenblum, but overall the number of new writers appearing in the magazine fell. Ashley suggests this was because the magazine's reputation was now high, and Dozois received hundreds of manuscripts a week, making it harder for new authors to break through.
In 2004, Asimov's was included in a list of magazines available for school fundraising drives. The mother of a 13-year-old girl who bought a copy complained about the magazine, which contained strong language and other material she objected to, and the complaint led to some negative news coverage, described by the Encyclopedia of Science Fiction as "over-sensationalized".
Paul DiFilippo and Peter Heck took over the book reviews from Baird Searles in 1994, and Spinrad began contributing critical essays. A column on role-playing games, by Matthew Costello, began in 1996 and lasted for four years. James Patrick Kelly and Robert Silverberg both began contributing columns during Dozois's tenure; Kelly's column, "On the Net", began in 1998, and Silverberg's "Reflections" started in the July 1994 issue. Silverberg's column had originally begun in Galileo, in 1978, and had moved to Amazing Stories from 1981 to 1994. It is still running in Asimov's as of 2023.
Dozois's editorship was well regarded in the field. Dozois won the Hugo Award for best professional editor every year from 1988 to 2004 with only two exceptions, in 1994 and 2002, and Ashley describes his time at Asimov's as "one of the greatest of all editorial careers". Dozois made Asimov into "the most important magazine of its generation", according to the Encyclopedia of Science Fiction, which comments that Dozois's success "stimulated the sf field to rebuild and regenerate itself after the identity crises it had gone through in the 1960s and 1970s". In 2014 Gary Westfahl praised the "creative editors of the 1980s and 1990s, such as Gardner Dozois of Asimov's Science Fiction and Gordon Van Gelder of The Magazine of Fantasy and Science Fiction", but added that "such editors were no longer the most important figures in the field".

### Williams (2004 – present)

In Williams' first editorial, in the January 2005 issue, she made it clear she did not plan to make dramatic changes to the approach established by McCarthy and Dozois. Williams reinstated the letter column, and began an intermittent non-fiction column, "Thought Experiments", starting with a reminiscence by Roger Ebert of his involvement in science fiction fandom. To mark the 30th anniversary of the magazine in 2007, she published a 30th Anniversary Anthology.
She won the Hugo Award for short-form editor in 2011 and 2012.
