Mark Zuckerberg: Facebook changes reduced time spent on site by 50 million hours a day in Q4
Facebook CEO Mark Zuckerberg said Wednesday that the changes the company made to its service last year reduced time spent on the site by 50 million hours per day, or 5 percent. "Already last quarter, we made changes to show fewer viral videos to make sure people's time is well spent. In total, we made changes that reduced time spent on Facebook by roughly 50 million hours every day. By focusing on meaningful connections, our community and business will be stronger over the long term," Zuckerberg wrote.
