History of iPhone

Mobile content
Mobile application development, also known as mobile apps, has become a significant mobile content market since the release of the first iPhone from Apple in 2007. Prior to the release of Apple's phone product, the market for mobile applications (outside of games) had been quite limited. The bundling of the iPhone with an app store, as well as the iPhone's unique design and user interface, helped bring a large surge in mobile application use. It also enabled additional competition from other players. For example, Google's Android platform for mobile content has further increased the amount of app content available to mobile phone subscribers.
