OpenOffice.org (OOo), commonly known as OpenOffice, was an open-source office suite. It was an open-sourced version of the earlier StarOffice, which Sun Microsystems acquired in 1999 for internal use. Sun open-sourced the software in July 2000 as a competitor to Microsoft Office, releasing version 1.0 on 1 May 2002. In 2011 Oracle Corporation, the then-owner of Sun, announced that it would no longer offer a commercial version of the suite and soon after donated the project to the Apache Foundation. Apache renamed the software Apache OpenOffice. Other active successor projects include LibreOffice and NeoOffice.
