What Facebook wants you to spend less time doing: passively scrolling through updates on your timeline, reading articles and watching videos, but not interacting with others. But, he says, "if we do the right thing, I believe that will be good for our community and our business over the long term, too." After a handful of former Facebook insiders began speaking out about social media’s addictive nature and deleterious impact on society, the company acknowledged for the first time in December that passive consumption of social media can be harmful to users’ mental health. In a blog post accompanying Zuckerberg’s announcement, Adam Mosseri, Facebook’s head of News Feed, said that the current changes would not be as extreme as those “tests”, and some public content will still appear in users’ feeds. Refresh of the News Feed algorithm will de-prioritize content shared by media and businesses in favor of that produced by friends and family, Zuckerberg says 
 
 Mark Zuckerberg announced a major overhaul of Facebook’s News Feed algorithm that would prioritize “meaningful social interactions” over “relevant content” on Thursday, one week after he pledged to spend 2018 “making sure that time spent on Facebook is time well spent”. It uses a process called ranking to determine which posts show up in people's news feed and in what order based on what Facebook thinks they will be most interested in. The impact will vary from page to page, driven by factors including the type of content they produce and how people interact with it.” 
 
 Zuckerberg wrote that the changes will likely result in people spending less time on Facebook – a change that may have negative impacts on the company’s bottom line. One of the ways we do this is by connecting people to meaningful posts from their friends and family in News Feed. The changes to News Feed will likely have a significant impact on the news media. Because space in News Feed is limited, showing more posts from friends and family and updates that spark conversation means we’ll show less public content, including videos and other posts from publishers or businesses. And the public content they do see more will be held to the same standard. Facebook maintains that active and “meaningful” interaction can be good for people, so users will soon be more likely to see a post from a friend than a viral video. John Hegeman, vice president of product management for Facebook's news feed, shrugged off the business implications of people watching fewer videos. People who want to see more posts from Pages they follow can choose See First in News Feed Preferences to make sure they always see posts from their favorite Pages.
– What you see when you log on to Facebook will be changing soon—because Mark Zuckerberg wants to make sure "the time we all spend on Facebook is time well spent." The Facebook CEO announced major changes to news feeds in a post Thursday, saying they've received feedback that "public content—posts from businesses, brands, and media—is crowding out the personal moments that lead us to connect more with each other." Zuckerberg said that from now on, "you can expect to see more from your friends, family, and groups," and the public content that does appear should be the kind that encourages "meaningful interactions between people." He gave the example of "tight-knit communities around TV shows and sports teams." In a blog post, Facebook said it will "predict which posts you might want to interact with your friends about, and show these posts higher in [your] feed." Zuckerberg acknowledged that the focus on interaction instead of passive consumption might cause people to spend less time on Facebook, but he said the change "will be good for our community and our business over the long term, too," the Guardian reports. The move follows criticism that Facebook and other social media sites exploit human psychology to make themselves addictive, though analysts say Facebook consumption was already beginning to tail off. "Facebook is responding to a decline in consumption, not just encouraging a decline in consumption," Pivotal Research analyst Brian Wieser tells USA Today.
