Comp Ace (コンプ エース , Konpu Eesu , short for "Comptiq Ace") is a Japanese computer game and manga magazine published by Kadokawa Shoten.
 "Comp Ace" began as a special edition version of another one of Kadokawa Shoten's magazines, "Comptiq".
 The first issue was released on March 26, 2005, and was published quarterly for the first three volumes which had cover illustrations by Itaru Hinoue of Key.
 Volumes four through nine where published bimonthly with cover art providved by Aoi Nishimata of Navel.

Gossip magazines (sometimes referred to as tabloid magazines) are magazines that feature scandalous stories about the personal lives of celebrities and other well-known individuals.
 This genre of magazine flourished in North America in the 1950s and early 1960s.
 The title "Confidential" alone boasted a monthly circulation in excess of ten million, and it had many competitors, with names such as "Whisper", "Dare", "Suppressed", "The Lowdown", "Hush-Hush", and "Uncensored".
 These magazines included more lurid and explicit content than did the popular newspaper gossip columnists of the time, including tales of celebrity homosexuality and illegal drug use.
Cosmic Stories (also known as Cosmic Science-Fiction) and Stirring Science Stories were two American pulp science fiction magazines that published a total of seven issues in 1941 and 1942.
 Both "Cosmic" and "Stirring" were edited by Donald A. Wollheim and launched by the same publisher, appearing in alternate months.
 Wollheim had no budget at all for fiction, so he solicited stories from his friends among the Futurians, a group of young science fiction fans including James Blish and C. M. Kornbluth.
 Isaac Asimov contributed a story, but later insisted on payment after hearing that F. Orlin Tremaine, the editor of the competing science fiction magazine "Comet", was irate at the idea of a magazine that might "siphon readership from magazines that paid", and thought that authors who contributed should be blacklisted.
 Kornbluth was the most prolific contributor, under several pseudonyms; one of his stories, "Thirteen O'Clock", published under the pseudonym "Cecil Corwin", was very successful, and helped to make his reputation in the field.
 The magazines ceased publication in late 1941, but Wollheim was able to find a publisher for one further issue of "Stirring Science Stories" in March 1942 before war restrictions forced it to close again.
Space Science Fiction Magazine was a US science fiction magazine published by Republic Features Syndicate, Inc. as part of a package of radio shows and related genre magazines.
 Two issues appeared, both in 1957.
 It published short stories by well-known writers, including Arthur C. Clarke and Jack Vance, but it was not successful, and the magazine ceased publication late in 1957.
Science Fiction Quarterly was an American pulp science fiction magazine that was published from 1940 to 1943 and again from 1951 to 1958.
 Charles Hornig served as editor for the first two issues; Robert A. W. Lowndes edited the remainder.
 "Science Fiction Quarterly" was launched by publisher Louis Silberkleit during a boom in science fiction magazines at the end of the 1930s.
 Silberkleit launched two other science fiction titles ("Science Fiction" and "Future Fiction) "at about the same time: all three ceased publication before the end of World War II, falling prey to slow sales and paper shortages.
 In 1950 and 1951, as the market improved, Silberkleit relaunched "Future Fiction" and "Science Fiction Quarterly".
 By the time "Science Fiction Quarterly" ceased publication in 1958, it was the last surviving science fiction pulp.
Sylph (シルフ , Shirufu ) is a Japanese shōjo manga magazine published by ASCII Media Works (formerly MediaWorks) and is sold monthly.
 The magazine was originally published on December 9, 2006 as a special edition version of MediaWorks' now-defunct "Dengeki Comic Gao!
" under the title "Comic Sylph" (コミックシルフ , Komikku Shirufu , normally written as "comic SYLPH") as a quarterly publication.
 On March 21, 2008, with the release of the sixth volume, the magazine was transferred over as a special edition version of ASCII Media Works' shōnen manga magazine "Dengeki Daioh".
 On May 22, 2008, the magazine became independent of "Dengeki Daioh" and was published as volume one of "Sylph" as the July 2008 issue as a bimonthly publication.
 On May 22, 2010, the magazine started to be published monthly.
 "Sylph" is one of the few magazines originally published by MediaWorks not under the "Dengeki" naming line, such as with "Dengeki Daioh", and "Dengeki G's Magazine", the first of which being "Active Japan" in 1995 which has been discontinued since 1998.
A magazine is a publication, usually a periodical publication, which is printed or electronically published (sometimes referred to as an online magazine).
 Magazines are generally published on a regular schedule and contain a variety of content.
 They are generally financed by advertising, by a purchase price, by prepaid subscriptions, or a combination of the three.
 At its root, the word "magazine" refers to a collection or storage location.
 In the case of written publication, it is a collection of written articles.
 This explains why magazine publications share the word root with gunpowder magazines, artillery magazines, firearms magazines, and, in French, retail stores such as department stores.
