Although Facebook remains far and away the top social network in terms of accounts, active users, and frequency of visits, it saw a 3 percent drop in active usage between the second quarter of 2013 and the fourth quarter, according to the latest study from GlobalWebIndex.
Facebook is growing as a mobile company, with roughly 618 million people checking Facebook from their phones and tablets. According to new figures released Thursday by App Annie, Facebook Messenger is the No. 1 iOS social networking application, in terms of monthly downloads. The Facebook native app is No. 3. Both Messenger and Facebook are also quite popular on Android, as well.
