Sonstiges » create a successful platform??

Hello,
Consider the market for smartphones. Nokia and Blackberry today are a shadow of their former glory. Their technology and products lag Apple and the Android ecosystem. But the triumph of Apple and Android is not from features and functions. It is from the app store on which external developers create value. Microsoft has gotten excellent reviews for the technology in its new phones, but it is the ability to create a successful platform that will determine its ultimate success.Is this right information about Platform Marketing Examples? I have gone through many related sources and also searched on the internet but didn't get the right solution.
please help.

Any help will be appreciated.
Thank you.
