Software such as Apple's discontinued Newsstand enabled the downloading and displaying of digital versions of magazines but did not allow pornographic material.
The new printing processes allowed photographic images to be reproduced easily in black and white, whereas printers were previously limited to engravings, woodcuts, and line cuts for illustrations.
[2] First appearing in France, the new magazines featured nude and semi-nude photographs on the cover and throughout; often, burlesque actresses were hired as models.
[2] The British magazine Health & Efficiency (now H&E naturist, often known simply as H&E) was first published in 1900, and began to include articles about naturism in the late 1920s.
Another early form of pornography were comic books known as Tijuana bibles that began appearing in the U.S. in the 1920s and lasted until the publishing of glossy colour men's magazines.
[6] In the 1940s, the word "pinup" was coined to describe pictures torn from men's magazines and calendars and "pinned up" on the wall by U.S. soldiers in World War II.
Penthouse was also the first magazine to publish pictures that included pubic hair and full frontal nudity, both of which were considered beyond the bounds of the erotic and in the realm of pornography at the time.
[11] In the late 1960s, some magazines began to move into more explicit displays often focusing on the buttocks as standards of what could be legally depicted and what readers wanted to see.
Some researchers have detected increasingly violent images in magazines like Playboy and Penthouse over the course of the 1970s, with them then returning to their more upscale style by the end of the decade.
[15] The fact that the U.S. incidence of rape had increased over the same period has cast doubt on any correlation between magazine sales and sex crimes.
[13] In the 1990s, magazines such as Hustler began to feature more hardcore material such as sexual penetration, lesbianism and homosexuality, group sex, masturbation, and fetishes.
[1][2][8] In the late 1990s and 2000s the pornographic magazines market declined, as they were challenged by new "lad mags" such as FHM and Loaded, which featured softcore photos.
Physique magazines mostly consisted of photographs of attractive, scantily-clad young men, and occasionally homoerotic illustrations by gay artists like George Quaintance and Tom of Finland.
The magazines contained no overt mentions or depictions of homosexuality and used the pretense of demonstrating bodybuilding techniques or providing photos as visual references for artists, but it was widely understood that they were purchased almost exclusively by gay men.
Shifts in the judicial interpretation of obscenity in the US and elsewhere led to physique magazines being supplanted in the mid-to-late 1960s by new publications which openly acknowledged a gay audience and featured nudity, and later hardcore sex.
