Facebook plans to change how its news feed works, playing up status updates from friends and family. On the flip side, it will deemphasize news articles and anything published by brands. Facebook is trying to foster "meaningful interaction" and make Facebook more of a force for good, CEO Mark Zuckerberg said. Facebook is coming off of a tough year, where it had to battle fake news and reports that Russian-linked groups attempted to influence the 2016 presidential election via ads on its service.
