UPDATE from SAI: "Note: This post has been edited from its original version, after we learned that the data we initially used was flawed. This chart has accurate data from comScore. Our initial chart showed time spent on Facebook had peaked. We can't determine that based on comScore's data because its previous data was unintentionally inflated due to existence of non-user requested URLs. Anyway, Facebook's engagement is definitely flat this year."
Time spent on Facebook on desktop computers in the U.S. has peaked and now it's falling according to data from comScore
