WASHINGTON (AFP) ― Newsweek announced Thursday it would end an 80-year run as a print magazine, taking the venerable publication all-digital in another sign of the woes of an industry struggling in the Internet age.

Tina Brown, editor-in-chief and founder of the online Newsweek Daily Beast Company, said the change means the magazine will “embrace the all-digital future ... We are transitioning Newsweek, not saying goodbye to it.”

“They didn’t stand out as being a must-read, and you have to be a must-read in some way.”

Doctor said that, even though Newsweek is a strong brand, it has to be able “to stand out in the clutter” to survive in the digital world.

Media analyst Rebecca Lieb of the Altimeter Group said Newsweek “has got to reinvent itself and it’s got to do so under very challenging circumstances.”

The Washington Post sold Newsweek to California billionaire Sidney Harman for one dollar in 2010, ahead of a deal with IAC to merge the magazine with the online operation to become known familiarly as “Newsbeast.”

At the time of the sale in 2010, Newsweek had piled up more than $70 million in losses over the prior two years and had forecast more red ink. After Harman’s death in 2011, his family ended its
