Penthouse Pets 1969
The hottests chicks of 1969

Penthouse magazine began publication in 1965, in the UK and in North America in 1969. It was Bob Guccione attempt to compete with Hugh Hefner's Playboy. Guccione offered editorial content that was more sensational than that of Playboy, and the magazine's writing was far more investigative than Hefner's upscale emphasis, with stories about government cover-ups and scandals.

The magazine was founded on humble beginnings. Due to Guccione's lack of resources, he personally photographed most of the models for the magazine's early issues. Without professional training, Guccione applied his knowledge of painting to his photography, establishing the diffused, soft focus look that would become one of the trademarks of the magazine's pictorials. Guccione would sometimes take several days to complete a shoot.

The magazine's pictorials offered more sexually explicit content than was commonly seen in most openly sold men's magazines of the era; it was the first to show female pubic hair, followed by full-frontal nudity and then the exposed vulva and anus. Penthouse has also, over the years, featured a number of authorized and unauthorized photos of celebrities such as Madonna and Vanessa Williams. In both cases, the photos were taken earlier in their careers and sold to Penthouse only after Madonna and Williams became famous. In the late 1990s, the magazine began to show more "fetish" content such as urination, bondage and "facials".
