News Corporation Chairman Rupert Murdoch has launched a stinging attack on Google and other online entities for stealing content.

At a conference of World Media Executives at Beijing's Great Hall of the People, Rupert Murdoch has taken aim at search engines like Google as internet parasites.

According to the News Corporation Chairman, the so-called "aggregators" on the internet steal content from traditional media organisations and, he says, the time has come for them to pay for it.

"If we do not take advantage of the current movement toward paid-for content, it will be the content creators - the people in this hall - who will pay the ultimate price and the content kleptomaniacs will triumph," he said.

Human rights groups have criticised China for hosting the media summit given the level of press censorship here.
