The Ubuntu story
ubuntu |oǒ'boǒntoō|

Ubuntu is an ancient African word meaning 'humanity to others'. It also means 'I am what I am because of who we all are'. The Ubuntu operating system brings the spirit of Ubuntu to the world of computers.
Where did it all begin?

Linux was already established as an enterprise server platform in 2004, but free software was not a part of everyday life for most computer users. That's why Mark Shuttleworth gathered a small team of developers from one of the most established Linux projects – Debian – and set out to create an easy-to-use Linux desktop: Ubuntu.

The vision for Ubuntu is part social and part economic: free software, available to everybody on the same terms, and funded through a portfolio of services provided by Canonical.
Ubuntu releases

The Ubuntu team broke new ground in committing to a programme of scheduled releases on a predictable six-month basis. It was decided that every fourth release, issued on a two-year basis, would receive long-term support (LTS). LTS releases are typically used for large-scale deployments.

Ubuntu is different from the commercial Linux offerings that preceded it because it doesn't divide its efforts between a high-quality commercial version and a free 'community' version. The commercial and community teams collaborate to produce a single, high-quality release, which receives ongoing maintenance for a defined period. Both the release and ongoing updates are freely available to all users.
