In a move that could be the biggest thing to happen to the Facebook news feed since it was introduced, it appears the social network is quietly testing a massive revamp that will add a lot more news to the feed.

As seen in screenshots that surfaced on Twitter on Friday morning, Facebook is experimenting with a new layout on mobile that highlights multiple news sections, with topics such as World & U.S., Sports and Food. However, the primary (and presumably default) section is still the classic news feed we're accustomed to seeing.
Facebook confirmed to Mashable that it's testing the new, sectioned news feed, in addition to the current format, though it's unclear if the feature will ever get an official launch.
While the feature being tested isn't entirely new — we've seen some versions of topic-focused feeds in the past on iOS — the format revealed in the latest Android-based screenshots haven't quite been seen before.
"People have told us they’d like options to see more stories on Facebook around specific topics they’re interested in," a Facebook spokesperson said via email. "So we have been testing a few feeds for people to view more and different stories from people and Pages based on topic areas."
