According to the report of American market research organization Gartner, Google's Android has surpassed RIM's BlackBerry operating system and other similar products and become the second largest mobile operating system after Nokia Symbian. By 2014, Android and Symbian together will account for 60% of all mobile phone operating systems sold, and by then, Android is expected to replace Symbian as the best-selling mobile operating system. Although Symbian smartphone software once propelled Nokia to become the leader in the previous generation of mobile phone markets, with the increasing prevalence of smartphones and the growing capacity of the market, mainly due to the influence of Apple's iPhone, iOS, and Google's Android mobile operating system, its market share has been declining sharply. Due to its still relatively large production volume of phones, Nokia still maintains the top position in market share, but Gartner predicts that by 2014, its market share will drop to 30.2%. Meanwhile, with the continuous increase of Android-based phones in 2009 and 2010, based on current sales volumes and projected sales volumes for the second half of this year, Android's market share will rise from 13.8% to 17.7%. After RIM launched the iPhone killer - the BlackBerry Torch last month, its market share continues to decline, but the BlackBerry operating system still accounts for 17.5% of all mobile phones sold in the market, although it has dropped by 2.4 percentage points compared to the same period last year. Phones with Apple's iOS operating system are also growing continuously. In 2010, the iOS operating system accounted for a market share of 15.4%, an increase of one percentage point compared to the same period last year. However, according to Gartner's forecast, by 2014, due to the continued growth momentum of Android, Apple's market share will drop to 14.9%.
