Steve Jobs introduced the first iPhone at Macworld in January 2007 as three devices in one: a widescreen iPod, a revolutionary mobile phone, and an internet communications device.
The presentation took place on January 9, 2007, at the Macworld Conference & Expo in San Francisco. Jobs emphasized the phone’s multi-touch interface, which replaced the physical keyboards common on many smartphones at the time.
The original iPhone went on sale in the United States on June 29, 2007. It combined telephone, music, web browsing, email, and visual voicemail features. Apple later expanded the product line with the App Store, which transformed the iPhone from a fixed set of built-in functions into a platform for downloadable software.
