Playboy will no longer publish nude photos - KOBI-TV NBC5 / KOTI-TV NBC2

(NBC News) After more than 60 years of baring it all, Payboy magazine hopes a little less skin will mean a lot more readers.

From the start Playboy was a playbook for social change, credited with helping to usher in the sexual revolution of the 50s and 60s, publishing nude photos of models and movie stars, and in the process becoming a cutting-edge, iconic brand recognized around the world.

But that position has changed dramatically, with subscriptions falling off dramatically. Now the magazine is changing in response, announcing early next year it will eliminate the nude photo spreads that made it famous.

Playboy pulled nude pictures from its website last year and company executives say traffic jumped from four million to 16 million unique users a month. The magazine will make the change in March. There will still be a Playmate of the Month, but editors say the pictures will be “PG-13.”
