In October 2008 Nokia announced the Nokia 5800 XpressMusic, the first device to ship with the new touch-centric S60 5th Edition, also known as Symbian^1, the first iteration of the platform since the creation of the Symbian Foundation. In November 2008 Nokia announced it would end mobile phone sales in Japan because of low market share. Nokia's global mobile phone market share peaked in 2008 at 38.6 percent. The same year, Nokia announced the acquisition of Trolltech and its Qt software development. Qt was a central part of Nokia's strategy until 2011, and it was eventually sold in 2012.
