News Corp has signalled its intent to start charging customers to access content across its websites.
Chief executive Rupert Murdoch said he was "satisfied" News Corp could produce "significant revenues from the sale of digital delivery of newspaper content".
News Corp, which owns the Times and the Sun in the UK and the Wall Street Journal in the US as well as MySpace, reported losses of $3.4bn (around £2bn) in the year to the end of June.
The Wall Street Journal already charges for much of its content and Murdoch has been mooting the idea of expanding this model to other outlets.
"The digital revolution has opened many new and inexpensive methods of distribution," Murdoch said.
"But it has not made content free. Accordingly, we intend to charge for all our news websites. I believe that if we are successful, we will be followed by other media.
"Quality journalism is not cheap, and an industry that gives away its content is simply cannibalising its ability to produce good reporting," he added.
However, to stop people moving away from News Corp sites if a 'pay wall' goes up all Murdoch would reveal was that News Corp would make its content "better and differentiate it from other people".
News Corp also has a large stake in BSkyB.
