SAN FRANCISCO - Facebook Inc on Thursday put an end to a test of splitting its signature News Feed into two, an idea that roiled how people consumed news in six countries where the test occurred and added to concern about Facebook's power.
The test created two streaming series of posts. One was focused on photos and other updates from friends and family, and a second was called an "explore feed." It was dedicated to material from Facebook pages that the user had liked, such as media outlets or sports teams.
The social media network decided to end the test and maintain one feed because people told the company in surveys they did not like the change, Adam Mosseri, head of the News Feed at Facebook, said in a statement.
"In surveys, people told us they were less satisfied with the posts they were seeing, and having two separate feeds didn't actually help them connect more with friends and family," Mosseri said.
The test began in October and took place in Bolivia, Cambodia, Guatemala, Serbia, Slovakia and Sri Lanka, and it quickly affected website traffic for smaller media outlets.
Mosseri said the company had also "received feedback that we made it harder for people in the test countries to access important information, and that we didn't communicate the test clearly."
He said Facebook would, in response, revise how it tests product changes although he did not say how.
Chief Executive Mark Zuckerberg has unveiled other changes to the Facebook News Feed in the past two months to fight sensationalism and prioritize posts from friends and family.
The world's largest social network and its competitors are under pressure from users and government authorities to make their services less addictive and to stem the spread of false news stories and hoaxes.
