Media mogul Rupert Murdoch has said Facebook should pay fees to "trusted" news producers for their content.
Facebook said last week that it would boost news sources users rank as most trustworthy, while shrinking the percentage of news posts overall in users’ news feeds.
Mr Murdoch, whose companies own the Wall Street Journal, Fox News, the New York Post and other media properties, said publishers are "enhancing the value and integrity of Facebook through their news and content but are not being adequately rewarded for those services".
He has previously criticised Google for the "theft" of news stories without payment.
The news industry has struggled as print advertising erodes.
Facebook and Google dominate the online market, together taking nearly half of global digital ad revenue, according to eMarketer.
