The print edition of New Media Age was axed last year
New Media Age has erected a paywall in order to "continue to provide the specialist knowledge that nma is loved for".
The majority of content now requires a paid subscription, with the exception of jobs, webinars, podcasts and the nma source directory.
Readers are now asked to pay £149 for an annual subscription or £172 a year for a group package for access to Marketing Week, Design Week and Creative Review, as well as New Media Age.
It does not appear that any of the other titles currently require a subscription.
Last June Centaur Media, which owns the titles, axed the print editions of New Media Age and Design Week.
In an email announcing the launch of the subscription service, Charlotte McEleny, news editor, said: "We've invested in nma.co.uk and the refreshed content will provide you with the vital news, insight and reviews you need to inform and implement your digital strategy."
In September Centaur Media recorded a £30 million pre-tax loss.
Earlier this year Centaur bought digital information business Profile Group, owner of Foresight News, in an £8 million deal, and secured extra funding to acquire more businesses.
No one from New Media Age was available for comment this afternoon.
