Facebook has released its 2015 year in review analyzing what users discussed most, and among the topics are pop-cultural obsessions.

"Star Wars: The Force Awakens" was the fourth most-discussed topic in the US during the year (no surprise there if you've looked at your news feed), according to Facebook, and the entertainers who inspired the most conversation included Ed Sheeran, Taylor Swift, and Caitlyn Jenner.

But nothing gets people talking like TV. Here are the shows Facebook says were most popular across the globe in 2015:

10. "Orange Is the New Black"

9. "Last Week Tonight with John Oliver"

8. "Grey's Anatomy"
