Mark Zuckerberg suffered a big loss on Friday, with Facebook shares down 4.5 percent after the company's founder announced a series of changes and reforms on the site.
Mark Zuckerberg said a few days ago that "a change in the way content is displayed on Facebook would make the time spent by users on the site more" valuable ", but it turned out to be very expensive.
The founder and chief executive of the company, which owns 14 percent of its shares, lost about $ 3.3 billion on Friday only after the company's shares continued to fall, and the fortune of the young billionaire was $ 74 billion on the Bloomberg index.
The decline has affected the $ 4.5 billion that Zuckerberg added to his fortune this year. Not only that, he has lost his place as the fourth richest person in the world and was replaced by Spanish billionaire Amancio Ortega.
"There is a lot of uncertainty about the economic impact of Facebook's changes in the way publications are displayed, but the long-term impact of advertisers, companies, brands and publishers will play a big role on Facebook," says financial analyst Scott Devitt in a research note.
Facebook has announced changes that will give priority to the publications of friends and relatives to appear on the newsfeed, with less exposure to news and content published by brands.
