2007: Spreading awarenessThe Linux Foundation, a non-profit organization to foster the growth of the operating system, is founded. It offers training for Linux newbies and networking opportunities for developers.

2010: Major WinAndroid, the Linux-based operating system for smartphones, outships all other mobile OSes.
