"Canonical, Ubuntu's parent company, has been working
towards moving Ubuntu into enterprise servers for some time now. We
tend to think of Ubuntu as the community favorite Linux and on
desktops. Ubuntu started coming into its own as a server operating
system in mid-2006 with Ubuntu 6.06LTS-the first Long Term
Supported version. When Wikipedia chose Ubuntu to run its servers,
Ubuntu officially arrived as a world-case server operating
system."
