From Wikipedia: World Wide Web Consortium:

The World Wide Web Consortium (W3C) is the main international standards organization for the World Wide Web (abbreviated WWW or W3).

Founded and headed by Sir Tim Berners-Lee, the consortium is made up of member organizations which maintain full-time staff for the purpose of working together in the development of standards for the World Wide Web.

W3C also engages in education and outreach, develops software and serves as an open forum for discussion about the Web.

The World Wide Web Consortium (W3C) was founded by Tim Berners-Lee after he left the World Wide Web Consortium (W3C) in October, 1994. It was founded at the Massachusetts Institute of Technology, Laboratory for Computer Science (MIT/LCS) with support from the European Commission and the Defense Advanced Research Projects Agency (DARPA), which had pioneered the Internet.

The Consortium is jointly administered by the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) in the USA, the European Research Consortium for Informatics and Mathematics (ERCIM) (in Sophia Antipolis, France), and Keio University (in Japan).

From Wikipedia: Internet Research Task Force:

The Internet Research Task Force (IRTF) is a sister group to the Internet Engineering Task Force (IETF). Its stated mission is “To promote research of importance to the evolution of the future Internet by creating focused, long-term and small Research Groups working on topics related to Internet protocols, applications, architecture and technology”.

The IRTF is managed by the Internet Research Steering Group (IRSG) which corresponds to the similar organization called Internet Engineering Steering Group (IESG) on the IETF side.

From Wikipedia: Internet Society:

The Internet Society or ISOC is an international, nonprofit organization founded during 1992 to provide direction in Internet related standards, education, and policy. It states that its mission is "to assure the open development, evolution and use of the Internet for the benefit of all people throughout the world".

Under the standards category, ISOC supports and promotes the work of the standards settings bodies for which it is the organizational home: the Internet Engineering Task Force (IETF), the Internet Architecture Board (IAB), the Internet Engineering Steering Group (IESG), and the Internet Research Task Force (IRTF).

From Wikipedia: Internet Engineering Task Force:

The Internet Engineering Task Force (IETF) develops and promotes Internet standards, cooperating closely with the W3C and ISO/IEC standard bodies and dealing in particular with standards of the TCP/IP and Internet protocol suite. It is an open standards organization, with no formal membership or membership requirements.
