Explore gave people a new feed of content to discover Pages and public figures they had not previously followed.
"People don't want two separate feeds". It was intended as a different way for people to consume news in the six countries it was tested - but ended up primarily encouraging them to read false stories. One was focused on photos and other updates from friends and family, and a second was called an "explore feed".
Facebook has decided that completely separating posts from your friends and family from posts shared by brands and publishers is a bad idea. This allows Facebook to serve more ads in between the content, in videos and elsewhere.
In a statement to the Guardian, Facebook said: "People have told us they want an easier way to see posts from friends and family, so we are testing two separate feeds, one as a dedicated space with posts from friends and family and another as a dedicated space for posts from Pages".
Mosseri admitted that people responded by saying that some users said the changes "made it harder for people in the test countries to access important information" and added that the social network is looking at how to announce tests more clearly.
Facebook confirmed Thursday it was pulling the plug on a test that removed content from publishers and businesses from the News Feed and put it in a separate "explore" feed.
Beyond individuals some news outlets had bristled at changes as it meant that their ability to reach an audience via Facebook fell by two-thirds. A Facebook representative did not immediately respond to a request for additional information.
"I hope Facebook will have more interest in what is happening inside its test countries", Slovakian journalist Filip Struhŕrik, who had earlier criticised the test, said on Twitter on March 1. "We concluded that Explore isn't an effective way for people to discover new content on Facebook".
Your news feed won't be splitting up after all.
The feature was launched in October 2017 as one of Facebook's attempts to make the News Feed more useful to its users. Join here for the latest on how people are making money - and how they're losing it.
