While 'smart' phones like the Blackberry existed, Apple's iPhone (led by Steve Jobs) combined a multi-touch interface, a high-quality web browser, and a mobile computer into one device. It eliminated physical keyboards in favor of a software-based UI. This invention triggered a massive social and economic shift, putting the power of the internet into billions of pockets. It launched the 'App Economy' and changed how humans socialize, navigate, work, and record history in real-time.
