Facebook announced sweeping changes to its News Feed on January 11, 2018, saying that it would prioritize what their friends and family share and comment on while de-emphasizing content from publishers and brands.
Shares of Menlo Park, California-based Facebook tumbled 4.5 per cent on Friday in NY, cutting Zuckerberg's fortune to US$74 billion on the Bloomberg Billionaires Index.
Facebook CEO Mark Zuckerberg just lost NZ$4.5b.
Numerous meaningful interactions taking place beneath Zuckerberg's post asked that more power be given to the user to decide what shows up in their feed, or to give users the option to only see the most recent posts.
Mr Navarra said: "The downranking of publishers' content in news feed is not likely to kill any publishers in the short or medium term, but it will add more reasons for them to think about how they make money, and whether a subscription-based business model is now the way to go as another big chunk of its traffic disappears and on-site ad revenue evaporates".
People who use Facebook know that it has made several tweaks to its news feed over the years. And it's like June 2016, when Facebook again said it would push posts from friends higher up in the feed, because "Facebook was built on the idea of connecting people with their friends and family". "And if we do the right thing, I believe that will be good for our community and our business over the long term too".
Last week, Zuckerberg said his resolution for 2018 was to "fix" the social network he co-founded.
The move away from news-related content may be a way for Facebook to step back from the political debate, which brings up issues known to ruin family get-togethers.
The shake-up comes as Facebook, which now has more than two billion users, battles critics who have accused it of allowing fake news and Russian propaganda to circulate.
"But recently we've gotten feedback from our community that public content - posts from businesses, brands, and media - is crowding out the personal moments that lead us to connect more with each other", he said.
Nic Newman, a digital media strategist who authors the Reuters Institute Digital Report for Oxford University, said the move is "not unexpected" because "it's been a pretty bad year for Facebook in terms of its PR" - referencing the criticism the company has faced over "fake news" and its increasing dominance, alongside Google, of the online advertising market. Facebook has introduced a series of changes meant to address the problem.
Messages and photos shared by friends and family will take priority instead. Since then, annual sales have soared from US$5.1 billion to an estimated US$40.2 billion past year - and the news feed has become increasingly crowded with advertisements and posts from brands and publications.
Facebook has previously been criticised for algorithms that may have prioritized misleading news and misinformation in people's feeds. That means posts like a friend asking for advice, recommendations for a trip or an article that prompts interaction, according to a post by Facebook's head of news feed, Adam Mosseri.
A large part of brands and media companies' strategies is to post articles and videos from their pages to engage consumers - items that aren't considered "meaningful interactions" between people.
Some hedge funds used Friday's drop in Facebook's stock to bolster their positions, said Joel Kulina, a senior trader at Wedbush. "In our view, making the feed more relevant should boost user and engagement growth over time".
It's easy to understand how we got here. Martin said. "This confirms that we will have to pursue other channels".
