On 9 January 2007, Apple CEO Steve Jobs introduced the original iPhone at the Macworld Conference & Expo in San Francisco. Jobs called it "a revolutionary and magical product" combining a phone, widescreen iPod, and internet communicator.
The device went on sale on 29 June 2007 at US$499–599. It established the modern smartphone paradigm — touchscreen, no physical keyboard, app ecosystem — and transformed multiple industries from photography to music to navigation.
