In the past few years more and more commercial entities have become part of the Internet, primarily to take advantage of the large number of Internet users and the inexpensive comunications it provides. This idea of sharing is responsible for the Internet's initial growth. If I want to submit a job to a supercomputer in Illinois or California, and I'm in Louisiana, I can send the instructions to an operator or directly to the computer without having to be present. The results can be delivered directly to me. Discussion of services via the Internet.
Nobody owns the Internet.
No single person, body or agency is in charge of it. The members as a group are the only authority. Anyone can join the IETF, attend meetings and work on technical developments. The Internet is currently funded by its members. Much federal research money has gone into its development but that has been almost entirely withdrawn.
