Android: Background history • In July 2005, Google acquired Android, Inc., a small company that developed software for mobile phones • In the following months, the former “Android, Inc.” team started working on a Linux-based OS for mobile devices • By the end of 2006, media and press was filled with news about Google entering the mobile market. • In November 2007, the Open Handset Alliance was announced. • OHA’s first project: Android.

14. Open Handset Alliance:Mission statement • Building a better phone for consumers Today, there are 1.5 billion television sets in use around the world. 1 billion people are on the Internet. But nearly 3 billion people have a mobile phone, making it one of the world's most successful consumer products. Building a better mobile phone would enrich the lives of countless people across the globe. The Open Handset Alliance™ is a group of mobile and technology leaders who share this vision for changing the mobile experience for consumers. • Innovating in the open Each member of the Open Handset Alliance is strongly committed to greater openness in the mobile ecosystem. Increased openness will enable everyone in our industry to innovate more rapidly and respond better to consumers' demands. Our first joint project as a new Alliance is Android™. Android was built from the ground up with the explicit goal to be the first open, complete, and free platform created specifically for mobile devices.
