On January 9, 2007, late Apple co-founder Steve Jobs unveiled the iPhone. At that moment, the world changed in meaningful ways, and the iPhone would go on to become Apple’s biggest money-maker. Apple’s (AAPL) iPhone also helped to launch the broader smartphone market into another era and aided developers around the world in turning small development houses into major businesses. Meanwhile, Apple’s competitors have generated bundles of cash in the smartphone market, and looking ahead, there appears to be no slowing down investment in the industry.

Here is some data to illustrate how important the iPhone has been to Apple (AAPL) and the industry.
