Penthouse Magazine

Penthouse magazine (Penthouse) is a male adult magazine, founded in 1965 by Bob Guthrie in the United Kingdom, initially sold on newsstands in the United Kingdom, and then entered the U.S. market in 1969, and in less than half a year, by virtue of the bold as well as explicit pornographic depictions, occupied a considerable portion of the market of U.S. adult magazines, and became the main competitor of Playboy.
