iPhones

The iPhone is a line of smartphones designed and marketed by Apple Inc. since 2007. Each generation runs Apple's iOS mobile operating system and is closely integrated with Apple's ecosystem of services and devices.

The first iPhone, released in 2007, combined a touchscreen interface with a mobile browser and a media player, helping to popularize multi-touch gestures. The App Store, launched in 2008, expanded the platform by enabling third-party apps. Over the years Apple redesigned hardware and software, moving from a physical home button to edge-to-edge displays and introducing biometric security such as Face ID and, previously, Touch ID.

Current iPhone models use Apple-designed system on a chip (A-series) with increasingly powerful processors and graphics, advanced camera systems, and support for fast wireless technologies including 5G. Displays have evolved from LCD to OLED, with high dynamic range and improved color accuracy. iPhones run iOS, which provides core apps, privacy protections, and seamless synchronization with iCloud, Apple Pay, and other Apple services.

Market and impact: The iPhone has been a leading product in the smartphone market, shaping hardware design, mobile software, and app ecosystems. Apple emphasizes privacy, security, and environmental initiatives, including recycling programs and the use of energy-efficient components.
