After years of experimentation, cancellations and redesigns, Facebook looks like it is finally going to launch in the coming weeks a news reading service built for mobile devices. The product is known as “Paper,” according to a source familiar with the matter, and it is similar to Flipboard, a buzzy mobile-focused news reading app. Paper looks to be either a standalone mobile application or a Web experience suited to mobile devices, according to this person. Facebook could launch the app before the end of January, this person said, though the timetable could change. Paper and Flipboard share a number of similarities, according to this person. Both essentially act as aggregators of rich media content, displaying a mix of news stories from publications like the New York Times or the Washington Post, along with status updates from Facebook users — all in a visually stunning “paper-like” format hearkening back to a time before digital devices.
