It was once the only choice for schoolboys seeking titillation, or perhaps more discerning older male subscribers who "read it for the articles". For a generation Playboy was almost a rite of passage for boys entering manhood. But now naked women, the very subject that built the Playboy global brand from the first edition, with Marilyn Monroe as the centrefold, to the present day, are being discarded.The radical move by an institution that was there at the start of the American sexual revolution in the early 1950s, has been triggered by the easy access to online pornography."You're now one click away from every sex act imaginable for free," Playboy's chief executive, Scott Flanders, told the New York Times.It is a calculated risk but Hugh Hefner, still editor-in-chief, has given it his blessing.Playboy will still have photo spreads of women in provocative poses but, from March next year, no nudity. Instead, Playboy will rely on the strength of its writing - which has a rich history, having published interviews with luminaries such as Martin Luther King and Malcolm X.Jeremy Gordin, founding editor of Playboy SA, says this will be a game-changer. "In the early '90s there were two rules that could not be broken. First: your Playmate and pictures of her had to be seen by Hef before they could be printed. Rule two - a Playmate had to preferably be blonde, and have "very robust mammalian protuberances"."Now, with this shift, from nude and banal to 'sexually provocative', a whole new vista opens up," he said. ..
