In addition to building a great OS that many people use, the Ubuntu project has developed an OS that those building other operating systems use as a basis to build from. This has come in the form of both internal partner projects and external derivative distributions. Together, these span languages, continents, and markets. Also, Ubuntu is tightly linked to Canonical Ltd.'s other projects, Launchpad and Bazaar. While Bazaar provides a compelling version control system, Launchpad provides a one-stop show for bugs, translations, and much more.
