Facebook has overhauled how it ranks the posts, videos and photos that appear in its users' News Feeds, introducing major changes on Thursday designed to put what friends and family have to say first.

In short, you'll see more posts from friends that have spurred lively debates in the comments. And you'll see fewer cooking videos from brands and publications. Prioritizing what your friends and family share is part of an effort by Facebook to help people spend time on the site in what it thinks is a more meaningful way.
