Companies such as Google, Microsoft and Yahoo have been lobbying U.S. politicians to introduce laws that would make Net neutrality mandatory. These moves have been opposed by broadband providers and some hardware manufacturers.
Berners-Lee characterized the issue as a U.S.-only problem at present. "In Europe, Net neutrality is the rule," he said.

"The Web has brought so many possibilities that it's hard to believe it's such a short time since Sir Tim and those pioneers created it," said McConnell.
