Apple introduced the first commercially successful smartphone in the iPhone line in 2007.
Apple unveiled the original iPhone on January 9, 2007, and released it in the United States on June 29 of that year. Steve Jobs presented it as a combination of a mobile phone, an iPod, and an internet communicator, emphasizing its multi-touch screen and software interface.
The original model helped shift smartphone competition toward touchscreens, downloadable software, and integrated online services. The App Store arrived in 2008, creating a major new software-distribution business and strengthening the iPhone ecosystem.
The iPhone was not the world’s first smartphone, and Apple did not invent mobile internet devices. Its importance came from combining existing technologies in a polished consumer product and building a platform that could support future models, accessories, and services.
