Known for its centerfolds of nude and semi-nude[4] models (Playmates), Playboy played an important role in the sexual revolution[5] and remains one of the world's best-known brands, having grown into Playboy Enterprises, Inc. (PEI), with a presence in nearly every medium.[6] 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.[7][8][9][10][11]
In 1971, Playboy had a circulation rate base of seven million, which was its high point.[65] The best-selling individual issue was the November 1972 edition, which sold 7,161,561 copies. One-quarter of all American college men were buying or subscribing to the magazine every month.[66] On the cover was model Pam Rawlings, photographed by Rowland Scherman. Perhaps coincidentally, a cropped image of the issue's centerfold (which featured Lena Söderberg) became a de facto standard image for testing image processing algorithms. It is known simply as the "Lenna" (also "Lena") image in that field.[67] In 1972, Playboy was the ninth highest circulation magazine in the United States.[68]
Sondra Theodore, Hugh Hefner's girlfriend from 1979 to 1981, lived with Hefner in his mansion with her children throughout the duration of her relationship. One of the most famous playboy bunnies, Theodore was featured on the cover of Playboy in 1977 and had many centerfold photo shoots throughout her time as a Playboy bunny. In the documentary series Secrets of Playboy, she spoke out about her experience and the mistreatment she received during her time in the house.[140] Theodore also spoke about her experience in a joint interview with her daughter for People magazine. In the interview they discuss the vastly different experiences and perspectives they had living in the mansion.[140]
CHICAGO, April 13, 2011 /PRNewswire/ -- For the sixth time in its 58-year history, Playboy magazine has released its list of Top 10 Party Schools. The much-talked-about rankings, featured in the magazine's May 2011 issue (on newsstands and online at www.playboydigital.com Friday, April 15) were determined by Playboy's editors with input from students, fans of Playboy's social media pages, alumni, feedback from Playboy campus representatives at schools across the country, and interviews with countless others. Additionally, other factors that were taken into consideration for the schools that made the list include their male-female ratios, academics, and the winning percentage of their sports teams, as well as their proximity to beaches, ski slopes and lively music scenes.
