Jabber, later renamed the Extensible Messaging and Presence Protocol (XMPP), is an open standard for instant messaging. XMPP was developed in the late 1990s and released for public use in 1999. Since then it has become the most popular instant messaging framework around, with everyone from small companies and universities deploying private Jabber servers to adoption by Google as the driving protocol for their enormous Google Talk system.
XMPP is favored by organizations large and small because the standard is decentralized, open, well established, can be isolated from the greater internet for secure intranet use, and is highly flexible and adaptable to the needs of individual organizations.
