Playboy readers who can only imagine what it would look like if a centerfold jumped right off the page are getting new specs to help them see into Hef’s world. The magazine’s June edition hits newsstands Friday equipped with 3-D glasses. Now the toy that has kids dodging dragons, meatballs and tall blue aliens at the movies will help adults focus on what is, at first glance, a very blurry Playmate of the Year. “What would people most like to see in 3-D?” asked Playboy founder Hugh Hefner. “Probably a naked lady.” Hefner makes no secret of hoping to capitalize on the popularity of 3-D movies such as “Avatar” and “How to Train Your Dragon,” even as he makes no secret of not quite getting what all the fuss is about. “In today’s print environment you have to create newsstand events,” said the editorial director of the Chicago-based magazine, Jimmy Jellinek. Playboy certainly must do something to get more people, especially younger people, to buy a magazine that has seen circulation plummet from 3.15 million in 2006 to 1.5 million today.
