As part of the move, Penthouse has shuttered its magazine division in New York, moving all operations to its Los Angeles headquarters. Subscribers, the magazine says, will receive instructions on how to convert their accounts.
"Penthouse Magazine will continue to be published in print during the transition to digital. No specific date to stop print publication of our flagship magazine has been set," said Ezra Shashoua, CFO of FriendFinder Networks, which owns the magazine.
The move comes just three months after one-time arch rival Playboy announced sweeping changes to its print magazine. December was the last print issue that featured nude models, with Pamela Anderson being the last woman to shed her clothes for the magazine.
While recent Penthouse circulation figures are not available, the magazine has been struggling for several years. In September 2013, its publisher went bankrupt. At the time, the company (whose holdings also include the AdultFriendFinder website) said it had not turned a profit since 2008. It was cleared to exit bankruptcy court three months later.
Penthouse itself was bought by FriendFinder in 2004 after it filed for bankruptcy.
Given the rise in popularity of adult content on the Internet, adult magazines on the whole have largely been relegated to the sidelines of the adult entertainment world. But 30 years ago, they were one of the industry's highest-profile presences in the mainstream world.
