  • Jabber's version 1.0 was released in May 2000. In the same year, Jabber protocols like XML streaming, messaging, presence etc, were established. In October 2000, jabbered 1.2 was released and the server dialback protocol was introduced to stop address spoofing.
  • In August 2001, the Jabber Software Foundation was established to coordinate the open source projects and commercial entities dependent on the Jabber technologies.
  • In October 2002, Internet Engineering Steering Group (IESG) approved the formation of the XMPP Working Group. In November, the first meeting of this group was held at IETF 55.
  • In 2004, the IETF published the core XMPP specifications: RFC 3920 and RFC 3921. It resulted in widespread adoption of XMPP.
  • In August 2005, Google Talk IM and Voice over Internet Protocol (VoIP) service were launched over XMPP. Later, reputed software companies like Apple, Cisco, IBM etc, started using XMPP in their products. For example, in 2010, Facebook introduced XMPP for its chat.
