Facebook, founded by CEO Mark Zuckerberg, is testing changes to its news feed.
If Facebook were to roll out the test more widely, it would mean the average user's main feed would be more populated with posts from people they know.
The changes are now being tested in six countries including Slovakia, Serbia and Sri Lanka, according to Filip Struhárik, a journalist at Slovakian news outlet Dennik N. The alternative version of Facebook shows non-promoted posts in a secondary feed, while Facebook's primary feed prioritizes content from user's friends and advertisements.
Only six countries - Guatemala, Slovakia, Serbia, Sri Lanka, Cambodia, and Bolvia - are now experiencing the test.
"The company's tests of an alternative News Feed dubbed the "Explore" Feed have progressed to a full rollout, the company now confirms".
Facebook confirmed the test, which was first spotted by Slovakian journalist Filip Struhárik, to Business Insider on Monday.
Facebook said the feed was "automatically customised for each person based on content that might be interesting to them".
Facebook has officially rolled out its new alternative News Feed, known as the Explore Feed, which is created to help users find more content on the social network.
"Pages are seeing dramatic drops in organic reach", Struhárik wrote. If implemented universally, the changes could hurt publishers who rely on Facebook to grow their audiences and, in turn, ad revenue.
"Earlier this year, many publishers identified subscriptions as a top priority, so we worked with a diverse group of partners to design, refine, and develop a test suited for a variety of premium news model", said a blog post by Facebook executives Campbell Brown, Alex Hardiman and Sameera Salari. "It's not global and there are no plans to be", he wrote on Twitter.
"People often tell us they want more from friends so we're testing two feeds, one for friend content and another dedicated to page content", Mosseri tweeted. For example, all of this is taking place in front of a broader backdrop Facebook is facing with its news feed - that Russian agents allegedly used it to spread misinformation during the 2016 U.S. election.
