The article states that "Playboy" magazine creators started "Omni", but I'm almost certain it was "Penthouse".
I would describe both Playboy and Penthouse as primarily pornography. As such, they were both wildly popular in the 1970s and early 1980s.
Omni was not that. I had a subscription to Omni from the first issue in 1978 until about 1983. Pop science, science fiction, fantasy art, interviews and features on space exploration policy... and junk science, UFOs, psychic powers, cults. News of the wierd.
> Playboy Magazine in the 50s and 60s had a reputation for, among other things, reviewing hi-fi systems, pop albums and surprisingly good fiction. Penthouse publisher Bob Guccione must have wanted some of the tech + fiction market because he and his wife Kathy Keeton launched Omni Magazine in 1978.
Either that got ninja-edited in the 8 minutes since you posted that comment, or you misread that paragraph.
Well, agreed that people didn't really buy Playboy or Penthouse for the articles. But it was pretty tame compared to PornHub and other online porn of today. You'd see breasts, maybe some pubic hair, but not much more, particulary in Playboy. Hustler was more explicit but none of them showed actual sex; you'd have to go to an "adult" bookstore or theater to find that.
