[http://www.openoffice.org/ OpenOffice.org ] (also referred as OO.o or OOo) is an office application suite available on several different operating systems.

[http://www.openoffice.org/ OpenOffice.org ] was initially created by a company called StarDivision in Germany under the name “StarOffice”. The source code of this application was later acquired by Sun Microsystems in August of 1999. To reduce the overwhelming share of market for Microsoft Office, the code of StarOffice was released to public in July of 2000. By doing this Sun Microsystems offered a free and open alternative to Microsoft office.

The Open version of StarOffice is unofficially called OpenOffice. But, since the trade mark of OpanOffice was already taken, they changed the name to [http://www.openoffice.org/ OpenOffice.org].
