Journalism Online, a company which seeks to help news organisations make money on the Web, said that more than 500 newspapers and magazines have agreed to join the venture.
Journalism Online, launched in April by three veteran US media executives, said publishers representing 176 dailies, 330 non-dailies and "leading global news sites" have signed letters of intent to become its affiliates.
"The websites of these publishers have more than 90 million monthly visitors from around the world," the New York-based company said in a statement.
It said a payment platform would go online in the fall which would allow subscribers to access paid content at the websites of the affiliates using a universal Journalism Online account.
"Affiliates will select their own approach to offering paid access, based on their respective brands, content and online readership," it said.
"Somebody could subscribe to one publication, others might want to get a package of content," co-founder Gordon Crovitz, a former publisher of The Wall Street Journal, told AFP.
"Some access will continue to be free and the most engaged users will be required to pay," he said.
Crovitz said the newspapers which have signed the letters of intent were "not all in the United States."
