It is increasingly clear that it is Facebook — not iOS or Android — that is the most important mobile platform. Facebook’s family of apps account for 24% of time spent on mobile, and the main Facebook app is responsible for 75% of that. Mobile apps thrive on “found time” — moments in line, or on the bus, or even on the couch where people simply want to look at something interesting — and Facebook consistently delivers for an increasing number of users all over the world. More impressively, Facebook isn’t just increasing its user base: its existing users continue to deepen their engagement with the app over time.
It's crazy how much power Facebook holds. Facebook is the internet for many users and that's where they spend the majority of their time.
As a writer and publisher, I'm not sure how I feel about some of the changes Facebook is implementing, but I have no choice but to play the game.
