SAN FRANCISCO — Facebook is pitching a new media initiative to license articles from some of the largest American news publishers and display that content inside the social network’s mobile app, according to three people with knowledge of the discussions.

The project involves the social network striking deals potentially worth millions of dollars to publishers including The New York Times, The Washington Post and Dow Jones, parent company of The Wall Street Journal, among others, said the people, who spoke on the condition of anonymity because they were not authorized to discuss it publicly.

The agreements would let Facebook pull in headlines and previews of the articles from partner publications for display inside a “News” tab in the Facebook app, they said. The talks with news organizations are continuing, they added, and it is unclear if any deals are close. Facebook hopes to introduce the effort by the end of the year.

Representatives for Dow Jones, The Times and The Post declined to comment. A Facebook spokeswoman confirmed that the company was aiming to include a “News” tab inside its app by the end of the year, but declined to comment further. News of the talks was first reported by The Journal.
