Playboy is an American men's lifestyle and entertainment magazine, formerly in print and currently online. It was founded in Chicago in 1953, by Hugh Hefner and his associates, and funded in part by a $1,000 loan from Hefner's mother. Notable for its centerfolds of nude and semi-nude models (Playmates), Playboy played an important role in the sexual revolution and remains one of the world's best-known brands, having grown into Playboy Enterprises, Inc. (PEI), with a presence in nearly every medium. In addition to the flagship magazine in the United States, special nation-specific versions of Playboy are published worldwide, including those by licensees, such as Dirk Steenekamp's DHS Media Group.
A Playmate is a female model featured in the centerfold/gatefold of Playboy magazine as Playmate of the Month (PMOM). The PMOM's pictorial includes nude photographs and a centerfold poster, along with a pictorial biography and the "Playmate Data Sheet", which lists her birthdate, measurements, turn-ons, and turn-offs. At the end of the year, one of the 12 Playmates of the Month is named Playmate of the Year (PMOY). Every Playmate of the Month is awarded a prize of US$25,000 and each Playmate of the Year receives an additional prize of US$100,000 plus a car and other discretionary gifts. In addition, Anniversary Playmates are usually chosen to celebrate a milestone year of the magazine.
The centerfold or centrefold of a magazine refers to a gatefolded spread, usually a portrait such as a pin-up or a nude, inserted in the middle of the publication, or to the model featured in the portrait. In saddle-stitched magazines, the centerfold does not have any blank space cutting through the image.
