When Steve Jobs launched the iPhone in 2007, I wonder if he realised how big the product would become. The iPhone and its associated app store are the central reason that Apple is worth $3 trillion today. Part of Apple's genius was to resist the urge to create all the iPhone apps in-house. Instead, they allowed outsiders to develop them, in a very regulated and secure environment.
During the week, it was pointed out that Apple now makes more money from the app store than the company's total revenues in 2007.
