WHO CONTROLS THE INTERNET ?

The Internet, a loosely-organized international collaboration of autonomous, interconnected network, support host-to-host communication through voluntary adherence to open protocols and procedures defined by internet standards.

Although the above definition is fundamentally correct, it conveys that no one is at the helm of the internet.
But in real  sense, some protocol is, and the parameters required for their usage, are essential in order to work on the Internet. A number of bodies are responsible for maintaining those protocol standard and parameters and these bodies steer the Internet in a significant sense. a brief description of these bodies is as follows.

1. INTERNATIONAL COUNCIL FOR ASSIGNED NAMES AND NUMBERS ( ICANN )

To reach another person on the internet, you have to type an address into your computer - a name or a number. that address has to be unique so computers know where to  find each other.
ICANN coordinate these unique identifiers across the world. Without this coordination, we wouldn't have one global internet.

2. INTERNET ENGINEERING TASK FORCE

The Internet Engineering Task Force ( IETF ) is a larger open International community of network designers, operator, vendors and researches concerned with the evolution of internet architecture and the smooth operation of the Internet. It is open to any interested individual. The actual technical work of the IETF is done in its working groups, which are organized by topic in several areas ( e.g.  Routing, transport, security etc. ). The IEFT working groups are grouped into area, and managed by Area Director, or Ads. The Ads are member of the Internet Engineering Steering Groups ( IESG ). Providing architectural oversight is the Internet Architecture   Board, ( IAB ). The IAB also adjudicates appeals when someone complains that the IESG has failed. The IAB and IESG are chartered by the Internet Society ( ISOC ) for these purposes. The Internet Assigned Numbers Authority ( IANA ) is the central coordinator for the assignment of unique parameter values for internet protocols. The IANA is chartered by the Internet Society (ISOC)

to act as the clearinghouse to assign and coordinate the use of numerous Internet protocol parameters.

The World Wide Web Consortium ( W3C ), is an international community that developed standards to ensure the long-term growth of the web. Founded and headed by Sir Tim Berners-Lee, the consortium is made up of member organization which maintain full-time staff for the purpose of working togeather in 

the development of standards for the World Wide Web. It is also

engaged in education and outreach, develops software and serves

as an open forum for discussion about the web
