Last month, Cory Jones, a top editor at Playboy, went to see its founder Hugh Hefner at the Playboy Mansion.

In a wood-paneled dining room, with Picasso and de Kooning prints on the walls, Mr. Jones nervously presented a radical suggestion: the magazine, a leader of the revolution that helped take sex in America from furtive to ubiquitous, should stop publishing images of naked women.

Mr. Hefner, now 89, but still listed as editor in chief, agreed. As part of a redesign that will be unveiled next March, the print edition of Playboy will still feature women in provocative poses. But they will no longer be fully nude.

Its executives admit that Playboy has been overtaken by the changes it pioneered. “That battle has been fought and won,” said Scott Flanders, the company’s chief executive. “You’re now one click away from every sex act imaginable for free. And so it’s just passé at this juncture.”
