Baidu Yi
Baidu Yi (, 易 Yì meaning "exchange" or "easy"), also known as "Baidu Yun", was an operating system for mobile devices until Baidu suspended it.  It is based on Google's Android but is a fork by Baidu, the dominant search engine operator in China.  It was announced on 2 September 2011 at the 2011 Baidu Technology Innovation Conference in Beijing.

Background 
On “2011 Baidu Technology Innovation Conference”, Baidu launched its first mobile terminal software platform, Baidu Yi.  It has integrated Baidu's intelligent search, cloud service, and various Baidu apps. Through collaboration with terminal manufactures, operators, mobile Internet service providers, and other upstream and downstream industry chains, it provides the users with convenient, abundant, and personalized mobile Internet experience. Baidu-Yi was developed especially for domestic Chinese smartphones, built on top of Android but replacing much of the original Google software with the network's own alternatives. There is Ting Music, Baidu Maps instead of Google Maps, The Baidu Yue e-reader, and Google Search has been stripped out and replaced with Baidu Search. In March 2015, Baidu officially stated that Baidu Yun is suspended.
