Question: Paul Raymond Publications designed a magazine in response to what two US adult magazines?

Context paragraphs:
Fantasy fiction magazine: A fantasy fiction magazine or fantasy magazine is a magazine which publishes primarily fantasy fiction.  Not generally included in the category are magazines for children with stories about such characters as Santa Claus.  Also not included are adult magazines about sexual fantasy.  Many fantasy magazines, in addition to fiction, have other features such as art, cartoons, reviews, or letters from readers.  Some fantasy magazines also publish science fiction and horror fiction, so that here is not always a clear distinction between a fantasy magazine and a science fiction magazine.  For example, "Fantastic" magazine published almost exclusively science fiction for much of its run.

Misdemeanor (UFO album): Misdemeanor is the twelfth studio album by the British hard rock band UFO.  After the disastrous tour supporting "Making Contact", UFO disbanded, with Phil Mogg spending time in Los Angeles, where he contacted (through Mike Varney) guitarist Atomik Tommy M.  Mogg decided to start a new band, involving the new American guitarist and Paul Gray, who had played bass guitar in the last UFO tour.  The three of them recruited former UFO keyboard player Paul Raymond and drummer Robbie France and started writing new material.  Chrysalis Records signed the new band as UFO and assigned experienced producer Nick Tauber for the recording process of a new album.  France resigned before the recording started and was replaced by former Magnum drummer Jim Simpson.  Paul Raymond quit the band during their US tour in August 1986 and was replaced for the rest of the tour by David Jacobson.

Paul Raymond Publications: Paul Raymond Publications is a British pornography publisher of monthly softcore pornographic magazine titles: "Escort", "Club International", "Mayfair", "Men Only", "Men's World", "Razzle", "Swing Mag", "Club DVD" and "Escort DVD".  It also publishes an adult website at which features both softcore and hardcore content since UK law does not allow hardcore R18 imagery to be sold on newsstands.  Their magazines are generally available in most newsagents, although some larger retailers require a modesty bag in order to protect minors from seeing gratuitous flesh on display on the cover.  As from 2013, their magazines are also available in digital format exclusively on the Paul Raymond digital newsstand.  Blue Active Media Ltd. is the parent company.

Electric Blue (TV series): Electric Blue was a softcore pornography show that aired mainly on the Playboy Channel in the early 1980s.  The show was produced in the UK.  Many prominent porn stars performed on this show, including Ginger Lynn, Christy Canyon, Sasha Gabor, Traci Lords, Blake Palmer, Janey Robbins, Rick Savage, Jay Serling, Laurie Smith, Heather Wayne, and Jessica Wylde.  Hustler Magazine Centerfold Model and 'scream queen' actress Gail Harris made appearances in many episodes.  This grouping of soft core porn first started in London under the direction of Paul Raymond, famous for his 'top shelf' men's magazines including "Men Only" and "Club International".  Paul Raymond also owned the Raymond Revuebar, a striptease club in Soho London.  The UK saw these shows on video tape, prior to them being picked by Playboy.  A film tie-in, titled Electric Blue - The Movie, was released theatrically in the UK in 1982 and on VHS in 1983, and featured Marilyn Chambers presenting archive nude footage of celebrities including Marilyn Monroe, Joanna Lumley, Jayne Mansfield and Jacqueline Bisset.

Men Only: Men Only is a British soft-core pornographic magazine published by Paul Raymond Publications since 1971.  However, the title goes back to 1935 when it was founded by C. Arthur Pearson Ltd as a pocket magazine (115×165 mm).  It set out its editorial stall in the first issue:

Mayfair (magazine): Mayfair is a British adult magazine for men.  Founded in 1965, it was designed as a response to US magazines such as "Playboy" and "Penthouse", which had recently launched in the UK.  For many years it claimed the largest distribution of any men's magazine in the UK.  It is a softcore magazine and is thus available in newsagents, although some larger retailers require a modesty bag to hide the cover.

Fortress (Sister Hazel album): Fortress, released in 2000, is Sister Hazel's third studio album.  It produced three singles.  "Change Your Mind" peaked at #59 on the US Hot 100 and at #5 on the US Adult 40, and was featured in the 2000 remake of Bedazzled starring Brendan Fraser Elizabeth Hurley, and Frances O'Connor.  "Champagne High" reached #22 on the US Adult 40, while "Beautiful Thing" failed to chart.

Kill Time Communication: Kill Time Communication (キルタイムコミュニケーション ) (KTC) is a Japanese publishing company focused on adult material, such as light novels, artbooks, adult magazines, manga.  The company was established in November 1995.

Core Magazine: Core Magazine Co. Ltd. (株式会社コアマガジン ) is a Japanese publishing company focused on adult material, such as adult magazines and "hentai" manga.  It also publishes "yaoi" titles, such as "Kirepapa".  The company was established in 1985 as Shōnen Shuppansha (株式会社少年出版社 ) .

Razzle (magazine): Razzle is a British soft porn magazine, founded in 1983, published by Paul Raymond Publications.  It currently focuses on the girl-next-door style pornography, offering cash for any photos of "readers' wives" printed; in the past, however, several notable glamour models were featured, including minor celebrity Joanne Guest.  It also includes the traditional "true" stories.
