Apple released the first iPhone in 2007, introducing its influential smartphone line to the public.
Apple announced the device on January 9, 2007, at the Macworld Conference & Expo in San Francisco. It combined a mobile telephone, an iPod-style music player, and an internet communicator in one touchscreen device. The original iPhone went on sale in the United States on June 29, 2007.
The product was significant because it replaced a physical keyboard and stylus with a multi-touch interface. It also helped establish the modern smartphone ecosystem that later included the App Store, introduced in 2008. That launch created a major new source of revenue for Apple, which is frequently ranked among the world's largest companies by market capitalization.
A common mix-up is confusing the announcement date with the retail release date: both occurred in 2007, but the announcement came several months earlier.
