MacStories delves into the history of third party services since the genesis of iOS with a beautifully visualized story posted today. It's remarkable to see the increasing role that third parties are playing in the stock iOS ecosystem.

It's also easy to see a looming problem for Google and Android on the horizon. Google has very few friends among these third parties because they've launched competing services of their own. Apple, and for that matter, Microsoft are in a position to benefit from this conflict immensely going forward. If someone wants the "Facebook phone", they'll find the solution much easier on a non-Google platform.
